Question 1

What is the primary function of the mitochondria in a eukaryotic cell?

Accepted Answer

The mitochondria produce ATP (adenosine triphosphate) through cellular respiration, serving as the cell's main energy source.

Question 2

Which organelle is responsible for protein synthesis in both prokaryotic and eukaryotic cells?

Accepted Answer

Ribosomes are responsible for protein synthesis in all cell types, reading mRNA sequences to assemble amino acids into proteins.

Question 3

What key structural feature distinguishes prokaryotic cells from eukaryotic cells?

Accepted Answer

Prokaryotic cells lack a membrane-bound nucleus; their genetic material floats freely in the cytoplasm, whereas eukaryotic cells have a true nucleus.

Question 4

During which phase of mitosis do chromosomes align along the cell's equatorial plate?

Accepted Answer

Chromosomes align along the metaphase plate during metaphase, ensuring equal distribution when the cell divides.

Question 5

What process allows water to move across a semipermeable membrane from an area of low solute concentration to high solute concentration?

Accepted Answer

Osmosis is the passive movement of water across a semipermeable membrane from a region of low solute concentration to high solute concentration.
