Question

the cell membrane is a flexible outer layer that protects the cell. controls what goes in and out through selective permeability, and helps the cell communicate with other cells. selective permeability means the cell membrane chooses what can enter or leave, keeping the cell healthy. the cell membrane moves molecules using different types of transport: passive transport: molecules move naturally from areas of high concentration to low concentration without using energy. osmosis: a type of passive transport where water moves across the membrane to balance water levels. active transport: molecules are moved against their concentration gradient using energy (atp). which type of transport does not require energy? choose the correct answer. passive transport active transport exocytosis

Explanation:

Passive transport moves molecules from high to low concentration without using energy. Active transport requires energy (ATP) to move molecules against their concentration gradient. Exocytosis is a form of active - transport for releasing substances out of the cell. Osmosis is a type of passive transport where water moves across a membrane. Since passive transport does not use energy, it is the answer.

Answer:

Passive transport
