Presentation Transcript

  1. WARM UP: CELL REVIEW • 1) Which type of cell does NOT have a membrane bound nucleus? • 2) Which organelle makes energy for the cell? • 3) Which organelle is the control center? • 4) This cell part protects the cell and decides what can enter and what can leave. • 5) This organelle cleans up all damaged cell parts. • EC. This organelle helps the cell reproduce and divide.

  2. Notes # 5: Cells and organelles

  3. Cell • Makes up organisms. • Smallest unit of life. • 2 types • prokaryotic: • no membrane bound organelles • eukaryotic: • have membrane bound organelles

  4. Organelle • “little organs” of the cell • Units inside the cell with a specific job

  5. (Protein: • differentiates one cell from another) • Nucleus: • control center of the cell • Contains DNA / info • Plasma membrane • decides what enters / leaves the cell • Ribosome: • make proteins • Rough endoplasmic reticulum: • houses ribosomes • makes proteins used inside &outside cell • makes lipids

  6. Smooth Endoplasmic Reticulum • detoxifies cell • makes lipids • Golgi body / apparatus: • packages and delivers proteins in and out of cell • Vacuole • storage of extra water and nutrients • Lysosome • breaks down old cell parts • Mitochondria: • Makes energy (ATP) for the cell

  7. Cytoplasm: • Fluid in cell containing water, nutrients used for metabolism • Centriole: • needed for cell division / reproduction • *Chloroplast: • makes food for plants • photosynthesis occurs here • *Cell wall: • rigid structure outside plasma membrane • support and protection for plant cells
