Cells Section 1 – Cell Structure A. Common cell structures – outer covering called cell membrane and internal gelatin like cytoplasm. A. B. Comparing cells – size and shape relate to function Two cell types A. Prokaryotic cells lack membrane – bound internal structures A. B. Only found in one-celled organisms such as bacteria Eukaryotic cells contain membrane – bound internal structures. Cell organization B. Cell organization A. Composes of cellulose, a cell wall grows, gives shape to, and protects the cells of plants, algae, fungi, and most bacteria. B. Cell membrane – protective layer around the cells A. For cells with cell walls, the cell membrane is inside the cell wall. B. A cell membrane allows food and oxygen into the cell and waste products out of the cell Cytoplasm – gelatin like substance inside cell membrane Cytoskeleton – scaffolding – like structure in cytoplasm which helps cell keep its shape In the cytoplasm, eukaryotic cells have organelles which help cell life processes. Nucleus – contains instructions for everything cell does; includes DNA
