  1. ANIMAL AND PLANT CELLS CELLS – The building blocks of all living things. Only visible with a microscope!

  2. PLANT and ANIMAL CELL • Pictures:

  3. CELL WALL • Rigid, tough, made of cellulose • Protects and supports the cell • PLANT • Picture:

  4. CELL MEMBRANE • Pictures: Plant Cell: Animal Cell: • Thin, covering, protects cells. • Protects the cell, performs active transport and passive transport, moves materials in and out of the cell. • PLANT AND ANIMAL

  5. CYTOPLASM • Jelly like substance that contains organelles • Pads and supports organelles inside the cell. • PLANT AND ANIMAL • Picture:

  6. NUCLEUS • Powerhouse of the Cell – “THE BIG KAHOONA” • Dense, ball shaped structure, contains DNA • Controls ALL of the cell’s activities • PLANT AND ANIMAL • Picture:

  7. NUCLEAR MEMBRANE • Thin covering over the nucleus • Covers and protects the nucleus • PLANT AND ANIMAL • Picture:

  8. NUCLEOLUS • Small dark area in the nucleus • Produces ribosome’s • PLANT AND ANIMAL • Picture:

  9. CHROMATIN • In the nucleus, made of DNA and protein, contains genes • Provides instructions for the cells activities, (growth, reproduction) • PLANT AND ANIMAL • Picture:

  10. ENDOPLASMIC RETICULUM – (ER) • Clear, tubular system of tunnels throughout the cell • Transports materials like proteins around the cell • PLANT AND ANIMAL • Smooth ER: • Rough ER: Difference: Contains Ribosomes (Dots on Rough ER)

  11. RIBOSOMES • Small specks made of RNA. Found in cytoplasm or on the rough endoplasmic reticulum • Makes proteins • PLANT AND ANIMAL • Picture:

  12. “MIGHTY MITOCHONDRIA” • Location in the cytoplasm, bean shaped • Supplies energy or ATP for the cell through cell respiration using glucose and oxygen • PLANT AND ANIMAL • Picture:

  13. VACUOLE • Large open storage area, smaller in animal cells • Storage tank for food, water, wastes or enzymes • PLANT AND ANIMAL • Picture: In Plant Cell: In Animal Cell:

  14. CHLOROPLAST • Green structures that contain chlorophyll • Captures sunlight and uses it to produce food through Photosynthesis • What is Photosynthesis? • PLANT • Picture:

  15. GOLGI COMPLEX • Small bags with tubes connecting them • Packages proteins for use in and out of the cell • PLANT AND ANIMAL • Picture:

  16. LYSOSOME • Small, round structures, containing enzymes • Digests older cell parts, food or other objects • PLANT AND ANIMAL • Picture: • In Plant Cell: • In Animal Cell:

  17. CYTOSKELETON • A web of proteins • Acts as both a muscle and a skeleton • Keeps the cell’s membrane from collapsing. • PLANT AND ANIMAL • Picture: • Magnified:

  18. KNOW YOUR CELL ORGANELLES! Stem Cells:
