Front

What organelle converts chemical energy from food into usable energy for the cell?

Back

Mitochondrion

Front

What is the process called when water diffuses through a selectively permeable membrane?

Back

Osmosis

Front

What is the primary cause of genetic variation during meiosis?

Back

'Crossing over' of chromosomes

Front

What process is used to replace damaged body cells?

Back

Mitosis

Front

In photosynthesis, what do plants use to produce oxygen and sugar?

Back

Water, sunlight, and CO2

Front

What is the function of the cell membrane?

Back

It regulates what enters and leaves the cell.

Front

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.
