Biology Overview

Branches of Biology

• Botany: study of plants and plant-like organisms
• Zoology: study of animals and animal-like organisms
• Microbiology: study of microorganisms such as bacteria, viruses, and fungi
• Ecology: study of interactions between organisms and their environment
• Genetics: study of heredity, genes, and genetic variation
• Biochemistry: study of chemical processes and substances that occur within living organisms
• Molecular Biology: study of biological molecules, their structure, and functions

Cell Biology

• Cell Structure: cell membrane, cytoplasm, nucleus, mitochondria, ribosomes, lysosomes
• Cellular Processes: metabolism, photosynthesis, respiration, cell signaling, cell division

Evolution

• Theory of Evolution: all species share a common ancestor and evolve over time through natural selection
• Mechanisms of Evolution: mutation, genetic drift, gene flow, natural selection
• Evidence for Evolution: fossil record, comparative anatomy, molecular biology

Biological Molecules

• Carbohydrates: sugars, starches, cellulose
• Proteins: polypeptide chains, enzymes, hormones
• Lipids: fats, oils, steroids
• Nucleic Acids: DNA, RNA, genes

Biological Systems

• Nervous System: brain, spinal cord, nerves, senses
• Circulatory System: heart, blood vessels, blood
• Immune System: defense against pathogens, immune cells, immune responses
• Respiratory System: breathing, lungs, airways
• Digestive System: mouth, esophagus, stomach, intestines
