What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is the role of the cell membrane in both plant and animal cells?

Back

The cell membrane acts as a gatekeeper, controlling the movement of substances in and out of the cell.

Front

What is a vacuole and what is its primary function?

Back

A vacuole is a storage organelle that can hold food, water, or waste for the cell.

Front

What is the nucleus and what is its significance in a cell?

Back

The nucleus is the organelle that directs all cell activities and contains the cell's DNA.

Front

What is the function of lysosomes in a cell?

Back

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

Front

What are ribosomes and what is their role in the cell?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

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 the transport of materials within the cell.

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.
