Question

Why is transport of materials neccessary in a plant or an qnimal.explain

Answer 1

In both animals and plants the transportation of materials are required for the movement of nutrients, waste products, circulation of water, etc.

Explanation:

• Plants perform several processes for making food and for the circulation of water and minerals, namely photosynthesis and transpiration.
• In the process of photosynthesis food is prepared by the green leaves of the plants, those food needs to be transported to other parts of the plants for their proper nutrition.
• Similarly, the transportation of water and minerals are required to compensate for the process of transpiration, and in the same way transportation also helps in the removal of excretory products and gases.
• Without the process of transport of these crucial minerals, and food plants will eventually die.
• Plants have specialized tissue for the transportation purpose and they are xylem and phloem.
• In animals too, transportation is important for the movement of the food, excretory wastes, hormones, etc.
• In animals, transportation takes place with the collective effect of circulatory and excretory systems.
• For the transportation purpose in animals specialized tissues called arteries, veins and capillaries are used.
