    Study Notes

    Cell Types and Structures

    • Prokaryotic cells have a single membrane where all cellular reactions occur within the cytoplasm.
    • Eukaryotic cells possess a nuclear membrane that surrounds the nucleus, differentiating them from prokaryotic cells.
    • Prokaryotic cells are considered the earliest type of cells on Earth.
    • A defining characteristic of prokaryotic cells is the lack of a nuclear membrane and organelles.
    • Eukaryotic cells feature well-defined chromosomes located in the nucleus.

    Differences Between Animal and Plant Cells

    • A key feature unique to plant cells is the presence of a cell wall, which provides structure and support.
    • Plant cells typically have a more regular shape due to their rigid cell walls, whereas animal cells are more irregularly shaped due to the absence of cell walls.
    • Animal cells have no cell wall, allowing for a varied and more flexible cellular structure.

    Organelles and Functions

    • Mitochondria are the organelles responsible for energy exchange within many cell types, facilitating cellular respiration and ATP production.
    • Lysosomes serve as digestion organelles, breaking down waste materials and cellular debris in a variety of cells.

    Size and Complexity of Cells

    • Generally, animal cells are larger than plant cells, but this can vary based on cell type.
    • Prokaryotic cells are often simpler in organization compared to the more complex structure of eukaryotic cells, which include multiple organelles.

    Common Misconceptions

    • Not all prokaryotic cells are photosynthetic; this feature is exclusive to certain types of prokaryotes, such as cyanobacteria.
    • Eukaryotic cells do contain organelles such as mitochondria and the Golgi apparatus, which are vital for various cellular functions.
