Life Science Final Review

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow carbon dioxide to enter the plant for photosynthesis and oxygen to exit.

Front

What causes genetic disorders?

Back

Genetic disorders are caused by DNA mutations or changes in chromosomes.

Front

What does the notation 'Aa' signify in genetics?

Back

The notation 'Aa' indicates a carrier of a recessive allele, meaning the individual has one dominant and one recessive allele.

Front

What is one of the main principles of cell theory?

Back

All cells are produced from other cells.

Front

What follows mitosis in the cell cycle?

Back

Cytokinesis follows mitosis and is the process where the cytoplasm divides, resulting in two daughter cells.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.

Front

Explain the difference between dominant and recessive alleles.

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is the significance of DNA mutations?

Back

DNA mutations can lead to genetic disorders, affect protein synthesis, and contribute to evolution.

Front

What is interphase in the cell cycle?

Back

Interphase is the stage of the cell cycle where the cell prepares for division, including DNA replication and growth.
