Cell Practice Test

Front

What is a prokaryote cell?

Back

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

Front

What is a nucleus?

Back

The nucleus is a membrane-bound organelle that contains the cell's genetic material (DNA) and controls the cell's activities. It is not found in prokaryote cells.

Front

What structures are found in animal cells?

Back

Animal cells contain structures such as mitochondria, Golgi bodies, and lysosomes, but do not have cell walls.

Front

What is cell theory?

Back

Cell theory states that all living things are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy through cellular respiration.

Front

What is the role of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is a plant cell?

Back

A plant cell is a type of eukaryotic cell that has a cell wall, chloroplasts for photosynthesis, and a large central vacuole.

Front

What is the function of lysosomes?

Back

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

Front

What is compartmentalization in cells?

Back

Compartmentalization allows different chemical reactions to occur simultaneously in different parts of the cell without interfering with each other.

Front

What is a cell wall?

Back

A cell wall is a rigid outer layer found in plant cells, fungi, and some bacteria, providing structure and protection.
