Cells, organelles and functions

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins for the cell.

Front

What type of cells lack membrane-bound internal organelles?

Back

Prokaryotic cells lack membrane-bound internal organelles.

Front

What is a vacuole and what is its function in plant cells?

Back

A vacuole is a sac within the cytoplasm that is full of fluid; it stores food, water, and other substances, and plants typically have one large vacuole.

Front

What is the role of the cell wall in plant cells?

Back

The cell wall provides structural support and protection; it is found in plant cells.

Front

Which organelle is responsible for photosynthesis?

Back

Chloroplasts are the organelles that use energy from sunlight to make sugar.

Front

What is the primary function of the nucleus in a cell?

Back

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

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 mitochondria in a cell?

Back

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

Front

What is the role of the endoplasmic reticulum (ER) in a cell?

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 function of the Golgi apparatus?

Back

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