Study Notes
Definition and Scope
- Biology is the scientific study of life and living organisms
- Examines structure, function, growth, evolution, distribution, and taxonomy of all living things
- Encompasses various disciplines, including botany, zoology, microbiology, ecology, and biochemistry
Branches of Biology
- Botany: study of plants
- Zoology: study of animals
- Microbiology: study of microorganisms
- Ecology: study of interactions between organisms and their environment
- Biochemistry: study of chemical processes within living organisms
- Molecular Biology: study of biological molecules and their interactions
- Genetics: study of heredity and variation
- Evolutionary Biology: study of evolution and its mechanisms
Biological Molecules
- Carbohydrates: provide energy and structure
- Proteins: perform various functions, including enzymes, hormones, and structural roles
- Lipids: provide energy, structure, and serve as hormones
- Nucleic Acids (DNA and RNA): contain genetic information
- ATP (Adenosine Triphosphate): energy currency of the cell
Cell Biology
- Cell: basic unit of life, consisting of plasma membrane, cytoplasm, and genetic material
- Cellular processes:
- Metabolism: energy conversion and chemical reactions
- Photosynthesis: conversion of light energy into chemical energy
- Cell division: replication and reproduction
- Cell signaling: communication and response to stimuli
Genetics and Evolution
- Mendelian Genetics: study of inheritance patterns
- Genotype: genetic makeup of an individual
- Phenotype: physical and behavioral traits expressed by an individual
- Evolution: change in species over time through natural selection and genetic drift
- Speciation: formation of new species
Ecology and Environment
- Ecosystem: community of living and non-living components interacting in an environment
- Biodiversity: variety of species, genes, and ecosystems
- Conservation Biology: preservation and protection of species, ecosystems, and biodiversity
- Environmental Impact: human effects on ecosystems and the biosphere
