What is a cell?

Back

A cell is the basic unit of life that makes up all living organisms. It is the smallest structural and functional unit of an organism.

Front

What are the two main types of cells?

Back

The two main types of cells are prokaryotic cells (without a nucleus, e.g., bacteria) and eukaryotic cells (with a nucleus, e.g., plant and animal cells).

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing protection and support.

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 are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and ribosomes.

Front

What is the role of the nucleus?

Back

The nucleus is the control center of the cell, containing genetic material (DNA) and regulating cell activities.

Front

What is the function of mitochondria?

Back

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

Front

What is the purpose of ribosomes?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into proteins.

Front

What is the difference between plant and animal cells?

Back

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

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, maintaining their shape.
