    Study Notes

    Cell Types

    • Prokaryotes are simple cells, exemplified by bacteria.
    • Eukaryote cells are larger and more complex, containing membrane-bound organelles.

    Cell Structure

    • Cytoplasm refers to the interior of the cell, excluding the nucleus.
    • The cytoskeleton provides structural support to the cell and assists in its movement.
    • All cells feature a cell membrane, a flexible barrier that encloses the cell.

    Transport Mechanisms

    • Diffusion involves the movement of particles from areas of higher concentration to lower concentration.
    • In comparing solutions, a hypertonic solution has a higher concentration of solutes, while a hypotonic solution has a lower concentration.
    • Endocytosis is the mechanism by which cells take in materials through the invagination of the cell membrane.
    • Phagocytosis is a type of endocytosis used by amoebas to ingest food and other materials.

    Cellular Functions

    • Cell specialization allows for the differentiation of cells to perform distinct tasks efficiently.
    • Facilitated diffusion utilizes protein channels to assist glucose in crossing the cell membrane.
    • Osmosis is the specific diffusion of water across a selectively permeable membrane.
    • Active transport is the energy-requiring process that moves materials across a membrane against their concentration gradient.
