    Study Notes

    Structure and Components

    • Plasma membrane: a thin, semi-permeable membrane that separates the cell from its environment
    • Cytoplasm: a jelly-like substance inside the cell where metabolic processes take place
    • Cytosol: a clear, watery liquid within the cytoplasm where many metabolic reactions occur
    • Organelles: specialized structures within the cell that perform specific functions
    • Nucleus: the control center of the cell where DNA is stored
    • Mitochondria: the powerhouses of the cell, responsible for generating energy through cellular respiration
    • Endoplasmic reticulum (ER): a network of membranous tubules and cisternae involved in protein synthesis and transport
    • Ribosomes: small organelles found throughout the cytoplasm, responsible for protein synthesis
    • Lysosomes: membrane-bound sacs containing digestive enzymes, involved in cellular digestion and recycling
    • Golgi apparatus: a complex of flattened sacs and tubules involved in protein modification and transport

    Functions

    • Metabolism: the process of converting energy and nutrients into the components of life
    • Protein synthesis: the process of creating proteins from amino acids
    • Cell signaling: the process of communicating with other cells and responding to environmental stimuli
    • Waste management: the process of breaking down and recycling cellular waste
    • Cell division: the process of creating new cells through mitosis or meiosis

    Specialized Cells

    • Nerve cells (neurons): specialized for transmitting information and controlling muscle and gland activity
    • Muscle cells: specialized for contraction and movement
    • Epithelial cells: specialized for protecting the body and regulating the exchange of substances
    • Connective tissue cells: specialized for supporting and connecting the body

    Cell Size and Shape

    • Cell size: varies greatly depending on the type of cell, with some cells being only a few micrometers in diameter
    • Cell shape: also varies depending on the type of cell, with some cells being spherical, cuboidal, or elongated
