Unit 3 Review - Cells

Front

What organelle is known as the powerhouse of the cell?

Back

Mitochondria - It is responsible for producing ATP through cellular respiration.

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to another solution, causing cells to swell as water enters.

Front

Define osmosis.

Back

The movement of water molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane.

Front

What is the main purpose of mitosis in multicellular organisms?

Back

To grow, replace dead cells, and repair tissues.

Front

What is exocytosis?

Back

A process where cells expel materials in vesicles that fuse with the cell membrane.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing cells to shrink as water leaves.

Front

What is facilitated diffusion?

Back

A process of passive transport that uses transport proteins to move molecules across the cell membrane.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy (ATP).

Front

What is the role of chloroplasts?

Back

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