Question

A. Transportation is a vital process in plants. Trees transport all the nutrients and water it needs for survival from its roots to the tips of the leaves.In the case of transportation in plants, the biggest constraint is water as it ends up being a limiting factor in growth. To overcome this problem, trees and other plants have the perfect system for the absorption and translocation of water.Plants contain a vast network of conduits which consist of xylem and phloem. This is more like the circulatory system that transports blood throughout the human body. Similar to the circulatory system in humans, the xylem and phloem tissues extend throughout the plant. These conducting tissues originate from the roots and move up through the trunks of trees. Later they branch off into the branches and then branching even further into every leaf, like spider webs.

Q 1) They are pipe-like, consisting of a group of specialised cells. They transport substances and form a two-way traffic in plants. Which of the following terms qualify for the features mentioned above?
a) Xylem tissue (b) Vascular tissue (c) Root hairs (d) Phloem tissue
Q2) The absorption of nutrients and exchange of respiratory gases between blood and tissues takes place in:
(a) veins (b) arteries (c) heart (d) capillaries
Q3) Which of the following is the main circulatory fluid in our body ?
a) Plasma (b) Lymph (c) Blood (d) None of these
Q4) Which one of the following contains haemoglobin?
a) RBC (b) WBC (c) Platelets (d) None of these
Q5) Blood platelets help in
(a) formation of urine (b) excretion of urine (c) sweating (d) blood clotting​
