What is the role of chloroplasts in plant cells?

Back

They conduct photosynthesis to convert light energy into chemical energy.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells; meiosis results in four genetically diverse gametes.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass while blocking others.

Front

What is the significance of 'crossing over' in genetics?

Back

It increases genetic diversity by exchanging genetic material between homologous chromosomes.
