Question

What is (are) the main difference(s) between passive transport and active transport? Group of answer choices Passive transport does not require any cellular proteins; active transport requires cellular proteins. Active transport works against gravity (for example, upwards from the roots of a tree); passive transport works with gravity (downward). Passive transport occurs primarily in single-cell organisms; active transport occurs primarily in multi-cellular organisms. Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.

Answer 1

Answer:

Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.

Explanation:

Active Transport works against the concentration gradient and therefore needs energy to make it happen

Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy
