    Study Notes

    Cell Membrane

    • The cell membrane (also known as the plasma membrane) regulates what enters and exits the cell, controlling the movement of materials through selective permeability.
    • It acts as a barrier, protecting the cell from its external environment.

    Organelle for Energy Production

    • The mitochondria is the organelle responsible for generating energy for the cell through a process called cellular respiration.

    Nucleus

    • The nucleus is the control center of the cell, containing most of the cell's genetic material (DNA) and responsible for controlling cell growth, division, and function.

    Cell Wall (Plant Cells)

    • The cell wall is a rigid, outer layer of plant cells, providing structural support, protection, and maintaining the cell's shape.
    • It is composed of cellulose, hemicellulose, and pectin, allowing for flexibility and strength.
    • The cell wall also helps to regulate the movement of materials in and out of the cell.

    Cytoplasm

    • The cytoplasm is the jelly-like substance within the cell membrane, where many cellular activities occur, including metabolic reactions, protein synthesis, and cell signaling.
    • It provides a medium for the movement of organelles and molecules, and helps to maintain the cell's shape.

    Vacuole (Plant Cells)

    • The vacuole is a membrane-bound organelle found in plant cells, responsible for storing water, salts, and other substances.
    • It helps to maintain the cell's osmotic balance, and also plays a role in the decomposition and recycling of cellular waste products.
