Question

1. directions

choose the correct answer for each row.
for each example, click to choose whether that example is considered active transport or passive transport.

	active transport	passive transport
diffusion	○	○
osmosis	○	○
exocytosis	○	○

Explanation:

Active transport requires energy to move substances against a concentration gradient. Passive transport does not require energy and moves substances along a concentration gradient. Endocytosis and exocytosis are active transport processes as they involve the cell using energy to take in or release substances. Diffusion and osmosis are passive transport processes. Diffusion is the movement of solutes from high - to low - concentration areas, and osmosis is the diffusion of water across a semi - permeable membrane.

Answer:

Endocytosis: Active Transport
Diffusion: Passive Transport
Osmosis: Passive Transport
Exocytosis: Active Transport
