Analyse the common points between the transport that takes place inside organisms (humans and plants) and transport systems around us.
Answers
Answer:
Explanation:
Both transport systems use water as the basis for transport since it is a good solvent, has a high specific heat capacity, is not too viscous and is unreactive
Answer:
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
