What is photosynthesis?

Photosynthesis is the process by which green plants use sunlight to synthesize foods with carbon dioxide and water.

What is cellular respiration?

Cellular respiration is the metabolic process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Define mitosis.

Mitosis is the process of cell division in which a single cell divides to produce two identical daughter cells.

What is the function of ribosomes?

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA.

What is a gene?

A gene is a segment of DNA that contains the instructions for building a specific protein.

Explain the role of DNA polymerase.

DNA polymerase is an enzyme that synthesizes new strands of DNA by adding nucleotides complementary to a template strand.

What is a ecosystem?

An ecosystem is a community of living organisms interacting with their physical environment.

Define homeostasis.

Homeostasis is the process by which biological systems maintain stability while adjusting to conditions that are optimal for survival.

What is natural selection?

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Describe the function of chlorophyll.

Chlorophyll is the green pigment in plants that captures sunlight for photosynthesis.
