Cell Organells Cytoplasm Mitochondria Nucleus Centrioles Smooth ER Rough ER Nuclear Envelope Chromatin Golgi Bodies Ribosomes Cell Membrane • Cytoplasm: Region between nucleus and the cell membrane. A clear, thick liquid • Mitochondria: Power house of the cell. Where cellular respiration takes place • Nucleus: Brain of the cell. Controls all cells activities. Surrounded by nuclear envelope • Nucleolus: produces and packages components of a ribosome • Chromatin: DNA and protein. Hard drive of the cell • Ribosomes: Produces proteins for inside the cell • Centrioles: helps organize microtubules in cell division • Endoplasmic Reticulum (ER) Rough – with ribosomes, smooth – without ribosomes. Transfers proteins to vesicles • Cell Membrane – the gate of the cell. Allows what gets in and out of the cell. • Golgi Bodies – Modifies ER products. Produces lysosomes. Carries substances outside of the cell. • Lysosomes – digestive enzymes to break down old organelles Plant Cells • Cell Wall – structure and protection • Chloroplast – Site for photosynthesis (make food) • Large Water Vacuole – for structure and storage
