Question

question 7
the movement of molecules from an area of high concentration to an area of lower concentration is called
a endocytosis
b facilitated diffusion
c osmosis
d diffusion
e active transport

Explanation:

• Endocytosis: It is the process of a cell taking in large particles or substances by engulfing them, not the movement of molecules from high to low concentration.
• Facilitated diffusion: Requires transport proteins but still moves molecules down a concentration gradient. However, the general term for movement from high to low concentration (without specifying need for proteins) is more relevant here.
• Osmosis: Specifically refers to the movement of water molecules across a semi - permeable membrane.
• Diffusion: The general process of molecules (can be any type of molecule, not just water) moving from an area of high concentration to an area of low concentration.
• Active transport: Moves molecules against a concentration gradient (from low to high) and requires energy.

Answer:

D. diffusion
