Chapter 2 2 (cells)

  1. 1. All You Need To Know About Cells
  2. 2. The basic unit of in living things is a . All living things are made up of one or more cells. structure cell
  3. 3. Cell Theory
  4. 4. Matthias Schleiden German Year: Stated: Botanist 1838 All plants are made up of cells
  5. 5. Theodor Schwann German Year: Stated: Zoologist 1839 The cell is the basic unit of structure in animals
  6. 6. Rudolph Virchow German Year: Stated: Doctor 1855 New cells come from cells that already exist. Cells divide to create new cells.
  7. 7. Cell Theory The Cell Theory states: All living things are made up of one or more Cells are the basic unit of structure in living things, and cells carry on all Cells come only from cells life processes 0ther living cells
  8. 8. Main Parts of the Cell Cell Membrane Cytoplasm Nucleus
  9. 9. Most cells have three main parts: 1. Thin structure that surrounds the cell. The cell membrane has 3 important jobs: - the inside of the cell - Supports and gives a cell its - movement of material into and out of cell Cell Membrane Protects shape Controls

  11. 11. Other Parts of the Cell Vacuole Mitochondria Ribosomes Golgi Bodies Lysosomes Endoplasmic Reticulum
  12. 12. Organelles are small structures that are suspended in the . Each organelle has a special job to do and keep the cell working properly. Mitochondria Release that the cell can use. Known as the “powerhouses” of the cell. Endoplasmic Reticulum Small, network of inside the cell. Substances move along these tubes from one organelle to another. Ribosomes Small rounded structures that make . These proteins are needed for growth and are involved in the cell processes. cytoplasm energy tubes proteins
  13. 13. Golgi Bodies The golgi bodies package and distribute to other parts of the cell. Golgi bodies also send materials to the outside of the cell. Vacuoles Small storage spaces in the cells cytoplasm. The vacuoles store Plant cells have one large vacuole and animal cells have many small vacuoles. Lysosomes Contains powerful that digest nutrient molecules in the cell. materials food and water. chemicals
