Active transport require the cell to expand energy whilst Passive transport require no energy from the cell in active transport.
Passive Transport moves molecules across membrane without the use of energy by the cell.
-Simple diffusion
-Facilitated diffusion
-Osmosis
Active Transport uses energy (ATP) to move molecules across membrane.
-Protein pumps
-Exocytosis
-Endocytosis (Phagocytosis & Pinocytosis)
Answer:
3- As cells get larger, the volume increases more than the surface area
Explanation:
As a cell develops, it grows larger and extends the cell membrane. Sadly, the volume rises greater than that of the surface area, and therefore the relative surface area usable to transfer resources to a unit cell volume declines gradually.
