Answer»

Answer:

Undersecretion of insulin causes diabetes MELLITUS type I while myxedema is CAUSED by thyroxine DEFICIENCY in adults. Hyposecretion of parathyroid hormone causes increased excitability of muscles and their sustained contraction referred to as parathyroid TETANY. Luteinizing hormone deficiency causes failure of ovulation as LH surge during midcycle stimulates rupture of Graffian follicle. 

So, the correct answer is option 'Luteinizing hormone- Failure of ovulation'.

Answer»

Aim

To prepare stained temporary mounts of

Aim

To prepare stained temporary mounts of

onion peel and

human cheek cells and to record observations and draw their labelled diagrams.

Theory

Plant cell to be studied in lab: Onion peel

The cells are very clearly visible as compartments with prominent nucleus in it.

The cell walls are very distinctly seen under the microscope.

The big vacuoles are also seen in each cell.

The cells can be stained very easily using safranin solution.

Animal cell to be studied in lab: Cheek cell

The cells are FLAT and irregular in shape, with no cell wall.

The nucleus can be seen very prominently in the center of the cell.

The nucleus of the cell is stained easily with the methylene blue stain.

The cell membrane and the cytoplasm can also be studied through these cells.

Functions of the Organelles:

Nucleus: Contains nucleic acid, DNA (genetic material) , which controls cell activities

Cytoplasm: Most chemical reactions take place here; controlled by enzymes

Cell membrane: Controls substances that move in and out of cell. It is partially permeable.

Cell wall :It is made up of cellulose, strengthens and protects the cell and gives definite shape to the cell.

Chloroplasts: Contain chlorophyll, which absorbs light energy and is a site for photosynthesis.

Mitochondrion: Site of respiration. It is known as the powerhouse of the cell.

Vacuole: Large, and filled with cell sap to help keep the cell TURGID. Acts as a store of water, sugars, in some cases, of waste products that the cell needs to excrete.

A. To prepare stained temporary mount of onion peel.

Materials Required

Onion, slides, coverslips, watch glass, petridish, forceps, needles, dropper, glycerine, blotting paper, blade/knife, safranin solution and a microscope.

Procedure

Take a medium sized onion, cut its outer surface with knife.

Use forceps to remove the peel of onion.

With the help of needle separate the small portion of epidermis (peel)

Keep dilute safranin solution in a watch glass.

Put this small peel in this watch glass with brush and allow it to stain for 3-5 minutes.

Transfer the stained peel to another watch glass that contains distilled water in it, to remove extra stain.

Take a clean dry slide and place two drops of water/glycerine on the centre of the slide.

Transfer the stained peel with needle and brush on the middle of the slide, if the peel curls straighten it and flatten it with brush and needle, do this gently.

With the help of blade cut the peel into a square shape.

Take a dry and clean coverslip and gently place it on the slide with the help of needle such that no air bubbles enter in it.

Gently press the coverslip with needle for even spreading of glycerine.

Remove the extra stain and water with the help of blotting paper.

Slide of Onion Peel and Cheek Cells 1

Clean the sides of the coverslip with dry blotting paper and place it under the lens of the microscope and record your observations.

Observations

The cells under observation are the plant cells. It consists of cell wall and large vacuoles. The nucleus is very prominent and is clearly visible.

8. पुनरुद्भवन पर एक निबन्ध लिखिये।Write an essay on Regeneration.​

Answer»

Answer:

Regeneration is an excellent ability of the adult tissue to repair any damage done to the body by autotomy i.e., voluntary separation of a part of the body, and accidental injury in nature or imposed by man under experimental conditions. This may involve replacement of dead or damaged CELLS, HEALING of a wound, replacement of lost part or the regeneration of the whole organism from a piece of body. It REFLECTS the reawakening of the developmental processes of morphogenesis and differentiation in the adult, when such processes normally cease in post-embryonic life of the organism.

This ability is almost present throughout the animal kingdom. Hence “the ability of an animal or organism to repair a wound, which PARTIALLY destroys tissues of the animal’s body or the damage involving the loss of an organ or larger part of the body which may be renewed, is thus called the process of regeneration.” Trembley first discovered it in Hydra in 1740. Of all the animals, coelenterates possess the GREATEST ability of regeneration, being highest in the polyploidy

It is common in planarians, nemertean and annelids, but poor in mollusks, nematodes, arthropods and echinoderms. Among vertebrates, it is remarkable in urodeles, but limited in anurans, fishes and lizards and very poor in birds and mammals.

In a healthy normal adult animal, many kinds of cells need replacement after a species -specific span of time. For example, there are approximately 25 × 1012 red blood cells in the active circulation of the human adult at any time.

About one percent of these cells are replaced daily; all the red blood cells are replaced every four months. Such replacement processes are also common in skin cells, cells in the lining of the uterus, and cells in the lining of the gastro-intestinal tract, and thus on the cellular level, it is a state of dynamic equilibrium.
