Active Transport, Endocytosis and Exocytosis

What is active transport?

1. A process that only occurs in plant cells.
2. A process that requires energy to move molecules across a cell membrane.
3. A process that involves the breakdown of molecules.
4. A process that does not require energy to move molecules across a cell membrane.

What is endocytosis?

1. A process that involves the direct movement of molecules across the cell membrane.
2. A process by which cells release substances out of the cell.
3. A process by which cells take in substances by engulfing them in a vesicle.
4. A process that occurs only in animal cells.

What is exocytosis?

1. A process by which cells take in substances by engulfing them in a vesicle.
2. A process that occurs only in plant cells.
3. A process by which cells release substances out of the cell.
4. A process that involves the direct movement of molecules across the cell membrane.
