What is a major difference between facilitated diffusion and active transport?
question 30 options:

active transport moves substances against the concentration gradient.

active transport uses proteins in the process.

facilitated diffusion moves molecules through the plasma membrane.

facilitated diffusion requires large amounts of energy.

The correct option is A) Active transport moves substances against the concentration gradient.

Explanation:

Facilitated diffusion can be described as the type of diffusion which occurs with the help of other molecules. For example, when integral proteins help in the transport of a molecule through the cell membrane. Facilitated diffusion is a type of passive transport as it allows molecules to move from an area of higher concentration to an area of lower concentration along a concentration gradient.

Active transport is the movement of molecules against the concentration gradient from an area of lower concentration to the area of higher concentration and hence, require energy.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
