Biology is the scientific study of life and living organisms, including their structure, function, growth, origin, evolution, and distribution.

What are the basic units of life?

The basic units of life are cells. All living organisms are made up of one or more cells, which carry out vital life processes.

What is the difference between a plant cell and an animal cell?

Plant cells have a cell wall and chloroplasts (for photosynthesis), which animal cells do not. Both have a nucleus, cell membrane, and other organelles.

Why is DNA important in biology?

DNA (deoxyribonucleic acid) contains the genetic instructions for the development, functioning, and reproduction of all living organisms.
