Study Notes
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 and viruses
- 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 the evolution of living organisms
Cell Biology
- Cell: basic structural and functional unit of life
- Cell membrane: semipermeable membrane surrounding the cell
- Cytoplasm: jelly-like substance inside the cell membrane
- Nucleus: control center of the cell where DNA is stored
- Mitochondria: site of cellular respiration
- Ribosomes: site of protein synthesis
Genetics
- DNA (Deoxyribonucleic acid): molecule containing genetic information
- Genes: units of heredity that determine traits
- Chromosomes: thread-like structures made up of DNA and proteins
- Genotype: genetic makeup of an individual
- Phenotype: physical and behavioral traits of an individual
- Dominant and recessive alleles: different forms of a gene that determine traits
Evolution
- Charles Darwin: proposed the theory of evolution through natural selection
- Natural selection: process by which organisms that are better adapted to their environment are more likely to survive and reproduce
- Speciation: process by which a new species emerges
- Fossil record: chronological record of the history of life on Earth
- Homologous structures: structures that are similar in different species due to common ancestry
