The plant BODY is generally divided into roots, stem, and leaves. The roots are in the soil, which is the major source of nutrients in plants. Water and other nutrients enter the plant through the roots.  The leaves are the food production centres. Using the sunlight and Carbon dioxide they synthesize food through photosynthesis in the chloroplasts.

Now, food from the leaves has to reach the other parts and the water, along with other nutrients has to reach leaves and other parts. All of this takes place through the vascular tissues of the plants. This is basically the transportation in plants.

You have already learned in earlier classes about the specialized cells and tissues in plants, which are the xylem and phloem. Together, they constitute the vascular STRUCTURE in plants.

When talking about transportation in plants we must discuss Xylem and Phloem. Xylem and Phloem tissues are present throughout the plant. They begin at the root and then move up to the stem, branches, and leaves.

The xylem tissue transports water and minerals from the roots to the leaves whereas the phloem tissue transports food from the leaves to the other parts of the plant. Xylem tissue has tracheids and vessel elements. Phloem tissue has companion cells and sieve tubes.

When transpiration in plants occurs, water gets evaporated from the leaves. This results in more water being pulled from the root. This phenomenon explains how water moves up in the plants, against gravity, without the use of any pump! The flow of water in the xylem tissues is unidirectional. It moves up the stem from the roots. It occupies the centre of the vascular bundle.

The phloem, on the other hand, is responsible for the translocation of the nutrients LIKE carbohydrates and amino acids from the leaves to other areas of the plants. Here, the flow is BIDIRECTIONAL. It moves up and down the stem. Phloem occupies the edge of the vascular bundle, as seen in the following figure. Food movement in the phloem occurs due to the pressure flow mechanism. The differences in the osmotic pressure help in the movement of food from the AREA of high concentration to areas of low concentration.

Factors Affecting Aquatic ECOSYSTEMS

Variability and change are natural processes in aquatic ecosystems, and ecosystem communities and individual organisms have in many cases adapted to different environmental conditions.

HUMAN effects on aquatic ecosystems can result from pollution, changes to the landscape or hydrological systems, and larger-scale impacts such as global climate change. The complexity of aquatic ecosystems and the linkages within them can make the EFFECT of disturbances on them difficult to predict. These linkages mean that damage to one component of the ecosystem can lead to impacts on other ecosystem components. INCREASING our UNDERSTANDING of aquatic ecosystems can lead to better practices that minimize impacts on aquatic environments.

Select natural and human influences on aquatic ecosystems are described in the following sections:

Natural factors

Human influences

Anthocyanins are natural plant pigments that have beneficial effects for the plant as well as for humans and animals. Dietary sources of anthocyanins are generally easy to identify due to their RED, blue, or purple color. Examples include berries and red-skinned grapes, apples, and pears and various vegetables such as radishes and red/purple cabbage. Anthocyanins may also be ingested through their use as a food additive and as dietary supplements, procured as anthocyanin-rich fruit extracts, powders, and purified compounds. The bioavailability of anthocyanins is considered to be limited; however, recent advances in targeted and nontargeted instrumentation have enhanced our detection capability, indicating that anthocyanin metabolism can be extensive, is complex, and that the full portfolio of anthocyanin metabolites are probably yet to be measured or characterized. Nonetheless, it is clear that anthocyanin intake is associated with various health benefits as demonstrated in a number of study designs ranging from HUMAN epidemiology and clinical trial intervention to screening and mechanistic studies in animals and cell culture models. Anthocyanin molecular targets include transporters and receptors, second messenger signaling molecules and kinase enzymes, transcription factors, promoters, and growth factors, and a host of oxidant defense enzymes. Despite the potential broad-spanning biological activities of anthocyanins, safety and toxicological concerns are relatively low. To date, there are no reports indicating adverse health effects with consumption of anthocyanins (in general) at usual dietary intake levels. The collective toxicological literature suggests that adverse effects occur only at extremely HIGH levels, although a complete toxicological assessment of anthocyanins is lacking (EFSA, 2013). Overall, anthocyaniningestion through food is unlikely to present a safety concern and may, in fact, impart health benefits. Currently, there is no recommended intake level of anthocyaninsto consume for optimal health or to avoid adverse effects (UL). Future anthocyaninsresearch and CONTINUED consumer interest in anthocyanin-containing foods and products with health benefits will undoubtedly present opportunities for pursuing dietary guidance recommendations

very interesting question !

you know, an atom contains MAINLY three subatomic particles ; electron, proton and neutron.

we also know, mass of electron is comparably negligible than mass of proton and that of neutron.

electron revolves around the nucleus in the ORBIT while proton and neutron are LOCATED at the CENTRE of the atom, this centre is known as nucleus.

its means, mass of an atom = mass of protons + mass of neutrons

hence, mass of an atom is concentrated in the centre i.e., nucleus.

so we can say, all mass of an atom is concentrated in the nucleus

Rail track runs parallel with SMALL and it is laid in such a way that there is small gap left in between them.

These small gaps are very IMPORTANT SINCE they provide required room for expansion of the rail TRACKS during summer and other climatic conditions.

Expansion also occurs due to the heat created from the constant friction between the WHEELS and the rail tracks.

This is because there is already more PRESSURE outside the PLANE and if there is no pressure INSIDE then plane will CRASH due to more pressure

The REGION in a sound wave, with higher pressure and density is called.. compression.. and that with low pressure and density is called..RAREFACTION..

Sound WAXES travel in LONGITUDINAL WAVES. Hence they have two different regions of pressure.

Because CONSUMERS MEANS producers and in the ecosystem PLANTS are DIRECTLY or indirectly
related to all animals.

Mosquitos WITHIN genus aedes are MAIN cause.

Viral transmission as well as the carrier incriminated THROUGHOUT most endemic areas is the yellow-fever mosquito, as well as Aedes aegypti.

In GENERAL the Asian tiger mosquito, as well as albopictus, is another prominent carrier of the virus. ANOPHELES mosquito carries parasites of malaria.

The basic HIERARCHY of cellular organisation is: Cells - Tissue - Organ - Organ SYSTEM.

So ORGANS are made up of two or more tissues. Skin is the largest organ in our body.

An organ system is a group of organs that work together to PERFORM one or more FUNCTIONS.

Each does a particular job in the body, and is made up of certain tissues.

There is no VACCINE to prevent HUMAN infection by this virus. Personal PROTECTION and the environmental management of mosquitoes are important in preventing illness. Prevent access of mosquitoes to an infected person with a fever. Protect yourself from MOSQUITO BITES at all times in dengue areas. The most imortant is prevent still water in your area as the mosquitoes breed in it

Shell number one can only hold 2 electrons, shell two can hold 8, and for the first EIGHTEEN elements shell THREE can hold a maximum of EIGHT electrons. ... So... for the element ofMAGNESIUM, you already know that the atomic number tells you THENUMBER of electrons. That means there are 12 electrons in a magnesiumatom.

Changes occur everywhere, every moment around us. Everything in the world is subject to change. Chemical changes: That change the chemical composition of the MATERIAL.Physical change: That are temporary and do not change the chemical composition of the material. They change only the STATE, colour, and texture.Reversible chages: They can be REVERSED.Irreversible changes: They cannot be reversed.
