    Flashcards

    Cell Wall

    A rigid structure surrounding the plant cell, composed mainly of cellulose, providing support and protection.

    Cell Membrane

    A thin, flexible layer that controls what enters and exits the cell, made of phospholipids and proteins.

    Chloroplast

    Green organelle in plant cells where photosynthesis takes place, containing chlorophyll, thylakoids, and a double membrane.

    Cytoplasm

    The gel-like substance inside the cell where many metabolic processes, like protein synthesis and energy production, occur.
