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 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 interactions between organisms and their environment • Genetics: study of heredity, genes, and genetic variation • 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 and proteins • Cell Biology: study of the structure and function of cells, the basic units of life
Biological Molecules
• Carbohydrates: provide energy for the body (e.g. sugars, starches, fibers) • Proteins: perform a wide range of functions in the body (e.g. enzymes, hormones, structural proteins) • Lipids: provide energy and structure for the body (e.g. fats, oils, cholesterol) • Nucleic Acids: contain the genetic information necessary for life (e.g. DNA, RNA)
Cell Structure
• Plasma Membrane: separates the cell from its environment and regulates what enters and leaves the cell • Cytoplasm: jelly-like substance inside the cell where metabolic processes take place • Nucleus: contains the cell's genetic material (DNA) • Mitochondria: generate energy for the cell through cellular respiration • Endoplasmic Reticulum: involved in protein synthesis and transport • Ribosomes: site of protein synthesis
Biological Processes
• Photosynthesis: process by which plants and some other organisms convert light energy into chemical energy • Cellular Respiration: process by which cells generate energy from glucose • Mitosis: process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell • Meiosis: process of cell division that results in four daughter cells with half the number of chromosomes as the parent cell (occurs in gamete formation)
