Chromosomes

Tiny, thread-like structures inside most cells of every organism.

Chromosome function

Chromosomes carry information about the organism in units called genes.

Gene inheritance

When living things reproduce, they pass their genes along to their children.

Growth in organisms

An organism grows because each new cell produced by the division of an old cell grows to its maximum size. Cells continue to divide to make sufficient cells for the adult organism.
