    Study Notes

    Cellular Organelles and Structures

    • The mitochondria is known as the 'power center of the cell' due to its role in generating energy for the cell through cellular respiration.

    Photosynthesis

    • Photosynthesis takes place in the chloroplasts of plant cells, converting light energy into chemical energy.

    Cellular Organelles and Structures (continued)

    • The Golgi apparatus is responsible for packaging, processing, and shipping out cellular products, including proteins and lipids.

    Cell Division

    • The centrioles are involved in the process of cell division, playing a crucial role in the formation of the spindle fibers.

    Cell Membrane

    • The main function of the cell membrane is to regulate what enters and leaves the cell, maintaining cellular homeostasis.

    Cell Types

    • Eukaryotic cells have a membrane-covered nucleus, distinguishing them from prokaryotic cells.

    Cytoplasm

    • The cytoplasm is the jelly-like substance within the cell membrane, responsible for various cellular activities, including metabolism, protein synthesis, and cell signaling.

    Cell Theory

    • According to the Cell Theory, all cells arise from pre-existing cells, emphasizing that cells are the basic units of life.
