Cell Organelles & Transport

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process of passive transport that allows substances to cross membranes with the assistance of special proteins, without the use of energy.

Front

Does facilitated diffusion require energy?

Back

No, facilitated diffusion does not require energy.

Front

What happens to a cell placed in an isotonic solution?

Back

The cell stays the same size because the concentration of solutes is equal inside and outside the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water through a selectively permeable membrane.

Front

What is the jelly-like substance located between the cell membrane and the nucleus?

Back

Cytoplasm.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain molecules to pass through while blocking others.

Front

What is the function of mitochondria?

Back

Mitochondria are the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.
