Branches of Biology

Botany: study of plants and their interactions with the environment
Zoology: study of animals and their interactions with the environment
Microbiology: study of microorganisms such as bacteria, viruses, and fungi
Ecology: study of the relationships between organisms and their environment
Genetics: study of heredity and variation in organisms
Biochemistry: study of the chemical processes that occur within living organisms
Molecular Biology: study of the structure and function of biological molecules such as DNA, RNA, and proteins
Cell Biology: study of the structure, function, and behavior of cells
Evolutionary Biology: study of the processes that have shaped the diversity of life on Earth

Cell Theory: all living organisms are composed of one or more cells, cells are the basic units of life, and all cells arise from pre-existing cells
Homeostasis: the ability of an organism or system to maintain a stable internal environment despite changes in the external environment
Heredity: the passing of traits from one generation to the next
Evolution: the process of change in the characteristics of a population over time
Photosynthesis: the process by which plants and some other organisms convert light energy into chemical energy
Respiration: the process by which cells generate energy from the food they consume

Carbohydrates: energy-rich molecules used by cells for energy and structural purposes
Proteins: molecules that perform a wide range of functions in cells, including catalyzing reactions and replicating DNA
Lipids: molecules that serve as energy storage and provide structural components of cells
Nucleic Acids: molecules that contain the genetic instructions for an organism (DNA and RNA)

Metabolism: the chemical reactions that occur within cells to maintain life
Growth and Development: the processes by which an organism grows and develops from a single cell to a mature adult
Response to Stimuli: the ability of an organism to respond to changes in its environment
Reproduction: the process by which an organism produces offspring
