What is the main difference between exocytosis and endocytosis?

• Exocytosis moves substances out of the cell, while endocytosis brings substances into the cell.

• Exocytosis moves substances into the cell, while endocytosis moves them out.

• Exocytosis and endocytosis are both passive transport processes.

• Exocytosis and endocytosis only occur in plants.

Diffusion and osmosis are both types of passive transport.

• True

• False

Endocytosis requires energy because the cell is actively bringing substances inside.

• True

• False

Osmosis is the diffusion of any substance across a cell membrane.

• True

• False

Exocytosis is how cells remove waste or secrete important substances.

• True

• False

A membrane that allows everything to pass through is called selectively permeable.

• True

• False
