Cell Structure and Function

Front

What are prokaryotes?

Back

Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Front

What is the function of the cell membrane?

Back

The cell membrane is a semi-permeable layer that surrounds the cell, controlling the movement of substances in and out.

Front

What is a vacuole?

Back

A vacuole is a membrane-bound organelle in cells that is used for storage of substances such as food, water, and waste.

Front

What structures are found in both eukaryotic and prokaryotic cells?

Back

Ribosomes are the structures that are always found in both eukaryotic and prokaryotic cells.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the difference between a cell wall and a cell membrane?

Back

The cell wall is a rigid outer layer found in plant cells and some prokaryotes, providing structure and protection, while the cell membrane is a flexible layer that controls entry and exit of substances.

Front

What is cytoplasm?

Back

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

Front

What is the function of mitochondria?

Back

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

Front

What is chloroplast?

Back

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