TRANSPORT IN PLANT

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transpiration is the consequence of which feature of plants?
A
the presence of symplast and apoplast pathways
B
the requirement for a transport system in plants
C
the requirement for leaves to exchange gases
D
the thin waxy cuticle on the lower epidermis of leaves
Explanation: 

Detailed explanation-1: -The movement of plants is through apoplast and it is absorbed due to transpiration pull and it is created due to the stress created in xylem sap.

Detailed explanation-2: -Transpiration helps in the conduction of water and minerals to different parts of the plants. Due to the continuous elimination of water from the plant body, there is a balance of water maintained within the plant. It maintains osmosis and keeps the cells rigid.

Detailed explanation-3: -Plants need to take up water, minerals and carbon dioxide, and transport them to the leaves for photosynthesis . They then move the products of photosynthesis to where they’re needed in the plant.

Detailed explanation-4: -The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw. Cohesion (water sticking to each other) causes more water molecules to fill the gap in the xylem as the top-most water is pulled toward the stomata.
