Cellular Parts S7L2b Relate cell structure (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions. Plant Cells Only in Plant Cells • Cell wall-rigid membrane around plant cell; made of cellulose and provides shape and support • Plastids (chloroplasts, leukoplasts, chromoplasts) -used in photosynthesis and product storage; have double membrane and provide color and cellular energy Basic Cell Structure • Cell membrane • The thin flexible boundary surrounding the cell • Cytoplasm – The watery, jelly-like part of the cell that contains salts, minerals and the cell organelles • Genetic material – the area of the cell where the DNA is stored – It regulates all the cellular activities Organelles • Little organs • Small, specialized cellular subunits • Helps a cell to move molecules, create and store energy, store information and perform many other functions • Different kinds of cells have different organelles Animal Cells Animal Cells Only • Cilia- short, hair-like extensions on the surface of some cells used for movement and food gathering • Flagella- long, whiplike extension on the surface of some cells used for movement Basic Cell Organelles for Plants & Animals • Vacuoles – Spherical storage sac for food and water • Cell membrane – membrane surrounding the cell that allows some molecules to pass through • Golgi bodies- flattened membrane sacs for synthesis, packaging and distribution • Mitochondria- rod-shaped double membranous structures where cellular respiration takes place • Endoplasmic Reticulum- folded membranes having areas with and without ribosomes used for transport of RNA and proteins • Nucleus- control center of the cell; location of hereditary information; surrounded by nuclear envelope • Ribosomes- Structures that make proteins; found on ER in the cytoplasm • Lysosomes- Spherical sac containing enzymes for digestive functions
