Front

What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles. Examples include bacteria and archaea.

Front

What are the main components found inside a prokaryote?

Back

Cytoplasm, genetic material (DNA), and ribosomes.

Front

What is the function of the vacuole in a cell?

Back

The vacuole stores nutrients, waste products, and helps maintain turgor pressure in plant cells.

Front

What process occurs in chloroplasts?

Back

Photosynthesis, the process by which plants convert light energy into chemical energy.

Front

What is the role of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What distinguishes plant cells from animal cells?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells do not.

Front

What is the cell membrane?

Back

The cell membrane is a protective barrier that surrounds the cell, controlling the movement of substances in and out.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site of many cellular processes.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis in the cell.
