Study Notes
What is Biology?
Biology is the scientific study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.
Branches of Biology
- Botany: study of plants
- Zoology: study of animals
- Microbiology: study of microorganisms
- Ecology: study of interactions between organisms and their environment
- Genetics: study of heredity and variation
- Biochemistry: study of chemical processes within living organisms
Levels of Organization
- Molecules: basic building blocks of life (e.g. carbohydrates, proteins, nucleic acids)
- Organelles: specialized structures within cells (e.g. mitochondria, chloroplasts)
- Cells: basic structural and functional units of life
- Tissues: groups of similar cells performing specific functions
- Organs: structures composed of multiple tissues
- Organ Systems: groups of organs working together to perform specific functions
- Organisms: individual living beings
- Populations: groups of organisms of the same species
- Communities: groups of different species interacting with each other
- Ecosystems: interactions between living and non-living components of an environment
- Biosphere: all living components of the Earth
Biological Molecules
- Carbohydrates: energy source for cells (e.g. glucose, starch)
- Proteins: building blocks of tissues (e.g. enzymes, collagen)
- Lipids: energy storage and structural components (e.g. fats, cholesterol)
- Nucleic Acids: genetic material (e.g. DNA, RNA)
Cellular Processes
- Photosynthesis: conversion of light energy into chemical energy
- Cellular Respiration: conversion of chemical energy into ATP
- Mitosis: cell division resulting in two identical daughter cells
- Meiosis: cell division resulting in four non-identical daughter cells
