Cell Structures and Functions (CP)

Front

What is a prokaryotic cell?

Back

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

Front

What organelle is present in plant cells but absent in animal cells?

Back

Chloroplasts are present in plant cells and are responsible for photosynthesis.

Front

What is the function of lysosomes?

Back

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

Front

What is a vacuole and its function in plant cells?

Back

A vacuole is a large storage organelle in plant cells that holds water, nutrients, and waste products.

Front

What is the role of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining homeostasis.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, converting food into energy (ATP) through cellular respiration.

Front

What is the difference between plant and animal cells?

Back

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

Front

What is the function of the nucleus?

Back

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

Front

What is the role of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is involved in protein and lipid synthesis; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).

Front

What are ribosomes and their function?

Back

Ribosomes are the sites of protein synthesis in the cell, translating messenger RNA into proteins.
