In the leaf, excess glucose is rapidly converted to starch, so we test leaves for starch to show that photosynthesis has happened, rather than testing for glucose.

We often indicate that light and chlorophyll are required for the process by adding them to the equation near the arrow.

You could demonstrate the effect of iodine solution on starch by adding a few drops of solution to a starch powder or starch suspension in a boiling tube. You can then discuss the fact that this colour change might be hard to see in a dark green leaf until the chlorophyll is removed.

Depending on student’s prior knowledge, you could discuss the structure of plant cells and explain that the starch is within the cells, the cells are surrounded by cell membranes and tough cellulose cell walls and that some leaves also have a protective waxy cuticle. The hot water treatment softens up the protective structures, and disrupts the cell membranes to let the chlorophyll out and the iodine solution in.

Ans :- The major difference Between Cerebellum and Cerebrum is their size. The cerebrum is the largest part of the brain and it nearly contributes 80% of the total weight of the human brain. The cerebellum makes up the remaining part of the brain. Voluntary movement, intelligence and memory are controlled by the cerebrum.

Themain differencebetween apoplast and symplast is that1- apoplast is a fully permeable route in which the water movement occurs by passive diffusion whereas symplast is a selectively permeable route in which the water movement occurs by osmosis.2- apoplast is composed of nonliving parts of a plant and symplast is composed of living parts of a plants.

The different enzymes involved in glycolysis act as kinases, mutases, and dehydrogenases, cleaving enzymes, isomerases or enolases.

TheCalvin cyclehas four mainsteps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generatingprocessis provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.

The C4 pathway initiates with a molecule called phosphoenolpyruvate (PEP) which is a 3-carbon molecule. This is the primary CO2 acceptor and the carboxylation takes place with the help of an enzyme called PEP carboxylase . They yield a 4-C molecule called oxaloacetic acid (OAA). Eventually, it is converted into another 4-carbon compound known as malic acid. Later they are transferred from mesophyll cells to bundle sheath cells. Here OAA is broken down to yield carbon dioxide and a 3-C molecule. The CO2 thus formed is utilized in Calvin cycle whereas 3-C molecule is transferred back to mesophyll cells for regeneration of PEP.Corn,sugarcane and some shrubs are example of plants that follows C4 pathway

A current is passed through the tungsten filament and heats it up.

As it is heated up the increased energy enables electrons to be released from the filament throughthermionic emission.

The electrons are attracted towards the positively charged anode and hit the tungsten target with a maximum energy determined by the tube potential (voltage).

As the electrons bombard the target they interact via Bremsstrahlung and characteristic interactions which result in the conversion of energy into heat (99%) and x-ray photons (1%).

The x-ray photons are released in a beam with a range of energies (x-ray spectrum) out of the window of the tube and form the basis for x-ray image formation

Lymph is the fluid that circulates throughout the lymphatic system. It is formed when the interstitial fluid is collected through lymph capillaries.

The cells present in the eye are cones and rods.

Phloemis composed of severalcell typesincluding sclerenchyma, parenchyma, sieve elements and companioncells. The so called “sieve element” may be more specifically referred to as a sieve tube member (angiosperms) or sievecell(gymnosperms and ferns).

different steps of water cycle include evaporation, transpiration ,condensation and participation and surface runoff .. evaporation the water present on the surface of Ocean evaporate by the sun heat..... this water vapour condenses to from tiny water droplets which float to air to form cloud or fog.

Lymph contains white blood cells. In particular, the lymph that leaves a lymph node is richer in lymphocytes. Likewise, the lymph formed in the human digestive system called chyle is rich in triglycerides (fat), and looks milky white because of its lipid content.

The composition of lymph varies a great deal, depending on where in your body it originated. In the lymphatic vessels of your arms and legs, lymph is clear and transparent, and its chemical composition is similar to blood plasma (the liquid portion of blood).

Lymph mainly consists of the following components: Proteins – Albumin, globulin, and fibrinogen.

Spleen is the centre for the formation of lymph.

Lymphatic vessels carry lymph not blood so B and D are incorrect. Both veins and lymphatic vessels are thin walled, carrying blood or lymph at low pressure so their is little elastic tissue needed to respond to changes in pressure as is seen in arteries.

Part of the way blood and lymph move through their respective vessels is by skeletal muscles squeezing the vessels and pushing the fluid through the vessels. The valves prevent the fluid from moving backwards just as squeezing a tube of toothpaste pushes the toothpaste out the open end, not the closed (= valved) end.

The process by which living beings are produced is called REPRODUCTION.

Reproduction is one of the most important characteristics of living being. Yes, it's true as reproduction helps in producing new species and new races. It helps to produce new off-springs. It helps to carry out life processes. So, reproduction is one of the most important characteristics of living beings.---------------------------

The tapetum is a specialised layer of nutritive cells found within theanther, of flowering plants, where it is located between the sporangenous tissue and theantherwall. Tapetum is important for the nutrition and development of pollen grains, as well as a source of precursors for the pollen coat.

Thetapetumis a specialised layer of nutritive cells found within the anther, of flowering plants, where it is located between the sporangenous tissue and the anther wall. Tapetum is important for the nutrition and development of pollen grains, as well as a source of precursors for the pollen coat.[1]The cells are usually bigger and normally have more than one nucleus per cell. As the sporogenous cells undergo mitosis, the nuclei of tapetal cells also divide. Sometimes, this mitosis is not normal due to which many cells of mature tapetum becomemultinucleate. Sometimes polyploidy and polyteny can also be seen. The unusually large nuclear constitution of the tapetum helps it in providing nutrients and regulatory molecules to the forming pollen grains.

These are three feature(i) There is a positively charged centre in an atom called the nucleus. Nearly, all the mass of an atom resides in the nucleus.(ii)The electrons revolve around the nucleus in well defined orbits.(iii)The size of the nucleus is very small as compared to the size of the atom.

Through the pores present in the walls of capillaries, some amount of plasma, proteins and blood cells escape into intercellular spaces in the tissues to form the tissue fluid or lymph. From intercellular spaces, it enters into lymphatic capillaries, which join to form lymph vessels, which open into larger veins. Lymph carries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into blood.

The cardiac cycle is the performance of the human heart from the ending of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, followed by a period of robust contraction and pumping of blood, dubbed systole.

The mainpurpose of the heartis to pump blood through the body; it does so in a repeating sequence called thecardiac cycle. Thecardiac cycleis the coordination of the filling and emptying of theheartof blood by electrical signals that cause theheartmuscles to contract and relax.

Thecardiac cyclecomprises a complete relaxation and contraction of both the atria and ventricles, and lasts approximately 0.8 seconds. Beginning with all chambers in diastole, blood flows passively from the veins into the atria and past the atrioventricular valves into the ventricles.

the complete sequence of events in the heart from the beginning of one beat to the beginning of the following beat a complete heartbeat including systole and diastole are called cardiac cycle.

Thecardiac cyclerefers to all of the events that occur from the beginning of one heartbeat to the beginning of the next and can be divided intotwoparts: a period of relaxation known as diastole and a period of contraction known as systole

Thecardiac cycleis the performance of thehuman heartfrom the ending of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, calleddiastole, following a period of robust contraction and pumping of blood, dubbedsystole. After emptying, the heart immediately relaxes and expands to receive another influx of bloodreturning fromthe lungs and other systems of the body, before again contracting topump blood tothe lungs and those systems. A normally performing heart must be fully expanded before it can efficiently pump again. Assuming a healthy heart and a typical rate of 70 to 75 beats per minute, each cardiac cycle, or heartbeat, takes about 0.8 seconds to complete the cycle.There are twoartialand twoventrical chambers of the heart; they are paired as theleft heartand theright heart—that is, the left atrium with the left ventricle, the right atrium with the right ventricle—and they work in concert to repeat the cardiac cycle continuously, (see cycle diagram at right margin). At the start of the cycle, duringventricular diastole-early, the heart relaxes and expands while receiving blood into both ventricles through both atria; then, near the end ofventricular diastole late, the two atria begin to contract artial sythole, and each atrium pumps blood into the ventricle 'below' it.Duringventricular sytholethe ventricles are contracting and vigorously pulsing (or ejecting) two separated blood supplies from the heart—one to the lungs and one to all other body organs and systems—while the two atria are relaxed (artial diastole). This precise coordination ensures that blood is efficiently collected and circulated throughout the body.

Three features of cardiac musclesare: (i)Cardiac musclesare involuntarymusclesthat contract rapidly, but do not get fatigued. (ii) Thecellsofcardiac musclesare cylindrical, branched, and uninucleate. (iii) They control the contraction and relaxation of the heart.

option D is the answer.it is related to kidney disorder.

Cardiac cycle helps in the circulation of blood. It includes systole (contraction of cardiac muscles) and diastole (relaxation of cardiac muscles). The cardiac cycle is a normal activity of thehuman heartand is regulated automatically by the nodal tissues- sinoatrial node (SA node) and atrioventricular node(AV node). The variation in the cardiac cycle results in increase or decrease of the cardiac output.

The occurrence of a cardiac cycle is illustrated by a heartbeat rate which is beats per minute. Our heart beats 72 times per minute and is stated as 72 cardiac cycles per minute.

Phyllotaxy refers to the pattern or arrangement of leaves on the stem or branch of a plant. It is of three types, alternate, opposite, and whorled phyllotaxy.

In alternate phyllotaxy, a single leaf arises from the node of a branch. This type of phyllotaxy is observed in the sunflower, mustard, and peepal. Plants with opposite phyllotaxy have two leaves arising from the node in opposite directions. It is found in guava andjamunplants. Plants with whorled phyllotaxy have three or more leaves arising from the node. It is found inAlstonia.

Ecosystem services are the many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems.There, ecosystem services are grouped into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and oxygen production; and cultural, such as spiritual and recreational benefits.

testosterone, estrogen, progesterone, oxytocin, and vasopressin.

Sex hormones are chemical substances produced by sex organs. For example, testosterone is the male sex hormone produced by the testis, and oestrogen is the female sex hormone produced by the ovary. These hormones affect the sexual features of an organism. Hence, they are known as sex hormones.Functions of sex hormones:Testosterone: This hormone brings about secondary sex characters in boys such as the growth of a beard, the voice becoming hoarse, development of reproductive organs, etc.Oestrogen: This hormone is responsible for the development of secondary sexual characters in females such as the enlargement of breasts, development of female reproductive organs, etc.
