Cell Structure

Front

What is a cell?

Back

A cell is the basic structural, functional, and biological unit of all living organisms. It is often referred to as the building block of life.

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 for many cellular 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, generating 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 larger vacuoles, while animal cells do not have these structures.

Front

What is the function of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and it also helps in transporting materials within the cell.
