    What is passive transport?

    Does not require energy to move substances.

    What is active transport?

    Moves substances against their concentration gradient using energy.

    What is osmosis?

    Water moves from high to low solute concentration.

    How does facilitated diffusion differ from simple diffusion?

    Facilitated diffusion requires channel proteins for transport.

    What happens in a hypertonic solution?

    Water moves out of the cell, causing it to shrink.

    What is a hypotonic solution?

    Has a lower solute concentration compared to another solution.

    What is isotonic?

    Two solutions have equal solute concentrations, resulting in no net water movement.

    What is turgor pressure?

    Pressure from water pushing against the cell wall in plant cells.

    What is plasmolysis?

    The process where plant cells lose water and shrink away from the cell wall.

    What is endocytosis?

    Process of taking large substances into the cell using vesicles.

    What is exocytosis?

    Process of expelling materials from the cell using vesicles.

    Why do cells need to be small?

    To maximize surface area for efficient transport of materials.

    What is the significance of surface area to volume ratio?

    Higher ratio allows for faster diffusion and efficient nutrient transport.

    What happens during mitosis?

    Cells divide to maintain small size and support cellular functions.

    What is the role of ATP in active transport?

    Provides energy to move substances against their concentration gradient.
