Which one among the following statements about facilitated transport in plants is correct?
general-sciencebiology-plants
- AAll passive transports are types of facilitated transport.
- BFacilitated transport is an example of active transport.
- CWater moves across plasma membrane by active transport.
- DFacilitated transport requires assistance of carrier proteins.
Explanation
Facilitated transport is a passive process in which substances move down their concentration gradient with the assistance of carrier or channel proteins. It is not the case that all passive transport is facilitated (simple diffusion is not), it is not active transport, and water crosses the plasma membrane passively by osmosis. Hence the correct statement is that facilitated transport requires the assistance of carrier proteins.
