Which one of the following statements about transport mechanism in plants is correct?
A
Diffusion of ions and small molecules across cellmembrane requires energy
B
Active transport of ions and small molecules across cell membrane against concentration gradient requires energy
C
Cells conserve energy and no energy is required for transport of ions and small molecules against concentration gradient
D
Cells do not transport ions across their membrane as these are charged molecules
Correct Answer: Active transport of ions and small molecules across cell membrane against concentration gradient requires energy
