Cell Organelles

Front

What is the function of the cell membrane?

Back

The cell membrane maintains homeostasis by controlling what enters and leaves the cell.

Front

What role does the central vacuole play in plant cells?

Back

The central vacuole stores water to maintain plant shape; if a plant needs water, it wilts.

Front

What is the primary function of mitochondria?

Back

Mitochondria create energy (ATP) from food and are the site of cellular respiration.

Front

How do lysosomes contribute to cellular function?

Back

Lysosomes use enzymes to digest bacteria, viruses, and old organelles, recycling old cell parts.

Front

What is the main function of the rough endoplasmic reticulum?

Back

The rough endoplasmic reticulum makes and transports proteins.

Front

What is homeostasis in the context of cell membranes?

Back

Homeostasis is the process by which a cell maintains a stable internal environment despite external changes.

Front

Describe the structure and function of mitochondria.

Back

Mitochondria have a double membrane structure and are responsible for producing ATP through cellular respiration.

Front

What is the significance of the central vacuole in plant cells?

Back

The central vacuole is crucial for maintaining turgor pressure, which helps keep the plant upright.

Front

What types of substances do lysosomes digest?

Back

Lysosomes digest bacteria, viruses, and old organelles using hydrolytic enzymes.

Front

Explain the difference between rough and smooth endoplasmic reticulum.

Back

Rough endoplasmic reticulum has ribosomes on its surface and is involved in protein synthesis, while smooth endoplasmic reticulum lacks ribosomes and is involved in lipid synthesis.
