Which statement concerning osmosis and active transport is correct? * 4 points
A. Active transport requires cell energy while osmosis does not
B. Both endocytosis and active transport require cell energy
C. Diffusion of gases and other small molecules requires no energy.
D. Neither facilitated diffusion nor osmosis require energy

This is a required question

A. Active transport requires cell energy while osmosis does not

Explanation:

Active and passive transport are important for living organism as they regulates the entry and exit of molecules and ions in a cell.

Active transport require cell energy in the form of ATP to maintain the right concentrations of ions and molecules in living cells while osmosis  is a type of passive transport and doe snot require cell energy this is so because ion concentrations in osmosis remain same both the side of the membrane and do not require cell energy to pump the molecules.

Hence, the correct answer is "Active transport requires cell energy while osmosis does not".

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic
