Function of the nucleus?

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

What does the mitochondria do?

Mitochondria produce ATP through cellular respiration, acting as the cell's energy powerhouse.

True or false: Ribosomes synthesize proteins.

True, because ribosomes read mRNA sequences to assemble amino acids into proteins.

Difference between rough and smooth ER?

Rough ER has ribosomes and synthesizes proteins, while smooth ER is involved in lipid synthesis and detoxification.

Fill in the blank: The __________ is responsible for packaging proteins.

Golgi apparatus.

What is the role of lysosomes?

Lysosomes digest macromolecules and recycle cellular components using digestive enzymes.

Question: What do chloroplasts do?

Chloroplasts conduct photosynthesis, converting sunlight into chemical energy stored as glucose.

Function of the cell membrane?

The cell membrane regulates the movement of substances in and out of the cell.

True or false: Vacuoles store nutrients and waste.

True, because vacuoles maintain cell turgor and store necessary substances.

What are the functions of the cytoskeleton?

The cytoskeleton provides structural support, aids in cell division, and enables cell movement.

Which organelle is known as the 'powerhouse'?

Mitochondria.

Question: What is the primary function of the plasma membrane?

It acts as a barrier and controls substance exchange through selective permeability.

Difference between prokaryotic and eukaryotic cells?
