    Study Notes

    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, RNA, and proteins

    Biological Molecules

    • Carbohydrates: provide energy and structure for cells
      • Examples: sugars, starches, cellulose
    • Proteins: perform a wide range of functions in cells
      • Examples: enzymes, hormones, structural proteins
    • Lipids: provide energy and structure for cells
      • Examples: fats, oils, cholesterol
    • Nucleic Acids: store and transmit genetic information
      • Examples: DNA, RNA

    Cell Structure and Function

    • Cell Membrane: regulates what enters and leaves the cell
    • Cytoplasm: jelly-like substance inside the cell membrane
    • Nucleus: contains 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

    Cellular Processes

    • Photosynthesis: process by which plants 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 identical daughter cells
    • Meiosis: process of cell division that results in four non-identical daughter cells

    Evolution and Genetics

    • Natural Selection: process by which individuals with favorable traits are more likely to survive and reproduce
    • Genetic Variation: differences in the genetic code between individuals
    • Genotype: the genetic code of an individual
    • Phenotype: the physical and behavioral characteristics of an individual
    • Mendelian Inheritance: the study of how traits are passed down from generation to generation
