Ans: The plant died due to excess coming out of water i.e. exosmosis.
19. What is the requirement of energy for developing pressure in roots?
Ans: All living cells require energy for their activity. So are the root cells, they also need the energy to develop pressure in the roots.
FAQs On Transport
How do cells transport?
Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis.
Does active transport require ATP?
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
Why is active transport needed?
Active transport is important because it allows the cell to move substances against the concentration gradient.
