    Study Notes

    Functions and Structures of the Cell

    • The cell is the basic unit of life, varying in size, shape, and function.
    • The cell membrane, made of phospholipids, surrounds and shapes the cell, acting as a boundary.
    • The cell membrane is semipermeable, allowing some substances to pass through while preventing others.
    • The cell membrane contains proteins such as channels, transporters, receptors, and markers.
    • The cytoplasm is a gel-like fluid inside the cell containing organelles, proteins, lipids, carbs, and electrolytes.
    • Organelles are structures in the cell that perform specific functions, such as the nucleus, endoplasmic reticulum, lysosomes, centrioles, cilia, flagella, and mitochondria.
    • The nucleus is the command center of the cell, containing chromosomes made of DNA and proteins.
    • Endoplasmic reticulum serves as a transportation system for materials in the cell, with smooth and rough types.
    • Lysosomes contain digestive enzymes and clean up the cell by breaking down waste.
    • Centrioles organize chromosomes during cell division.
    • Cilia sweep across the cell membrane, moving mucus and trapped particles out of the respiratory tract.
    • Mitochondria are the site of cellular respiration, converting glucose and oxygen into ATP energy and carbon dioxide.
