Front

What is the diffusion of water through the cell membrane called?

Back

Osmosis

Front

Which organelle directs all cell activities through the DNA located there?

Back

Nucleus

Front

How do particles move as a result of diffusion?

Back

They move from an area of high concentration to an area of low concentration.

Front

Which of the following does not expend energy: exocytosis, endocytosis, diffusion, or active transport?

Back

Diffusion

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts convert sunlight into energy through photosynthesis.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

What is the cell membrane's primary function?

Back

The cell membrane controls what enters and exits the cell.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecule.
