Back

Cell biology, genetics, evolution, ecology, and organismal biology.

Front

Define 'cell biology'.

Back

The study of the structure, function, and behavior of cells.

Front

What is the significance of genetics in biology?

Back

Genetics explains how traits are inherited and how genetic variation contributes to evolution.

Explain the concept of evolution in biological terms.

Back

Evolution is the process through which species change over time through natural selection and genetic variation.

Front

What is ecology?

Back

Ecology is the study of interactions between organisms and their environment.

Front

What is the role of photosynthesis in plants?

Back

Photosynthesis allows plants to convert light energy into chemical energy, producing glucose and oxygen.

Front

Describe the structure of a typical plant cell.

Back

A typical plant cell has a cell wall, chloroplasts, a large central vacuole, and various organelles like mitochondria and the nucleus.

Front

What is the function of mitochondria in cells?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

Front

Define 'homeostasis'.

Back
