Organelles and Their Function

EUKARYOTIC CELLS PROKARYOTIC CELL

Animal Cell Figure 7-5 Plant and Animal Cells Section 7-2 Go to Section:

Eukaryotic Cell Organelles and Function Nucleus Nickname: “The Brain” Function: holds the DNA (the genetic info!)

Nucleus Which type of cell has a nucleus? Eukaryotic or Prokaryotic

Eukaryotic Cell Organelles and Function Ribosomes Function: Assembles proteins

Eukaryotic cell organelles & function 2 Types: Rough ER: Rough appearance because it has ribosomes Function: makes and packages proteins (protein synthesis) Smooth ER: NO ribosomes Function: storage & makes membrane lipids 3. Endoplasmic Reticulum (ER)

Rough ER works with the Golgi

Eukaryotic Cell Organelles and Function Golgi complex Nickname: Post office Function: packages, modifies (changes), and transports proteins inside in and out of the cell Vesicles

Eukaryotic Cell Organelles and Function Lysosomes: circular, but bigger than ribosomes Function: break down food using enzymes What is the lysosome like?

Eukaryotic Cell Organelles and Function Mitochondria Nickname: “The Powerhouse” Function: Cellular respiration: makes (ATP) for cell activities Breaks down glucose to make ATP= cell respiration! ATP: is the major fuel for all cell activities that require energy

Eukaryotic cell organelles 7. Centrioles Make microtubules (provide structure for cell) Helps with cell division (mitosis) which occurs on microtubules

Eukaryotic cell structures 8. Cytoplasm Fluid that fills the cell 9. Cytoskeleton Give the cell structure (microtubules) The cell’s “skeleton”

Eukaryotic cell organelles 10. Cell (plasma) Membrane “Police man” Lets things in and out of cell Semi fluid boundary

Eukaryotic cell organelles 11. Vacuole Storage Not as prominent as plants vacuole

Protista: paramecium have a contractile vacuole to help get rid of too much water

Animal Cell

Now let’s talk about organelles only found in PLANT Cells!!

Eukaryotic Cell Organelles and Function Water Vacuole Function: stores water & salts When there is no water, the plant wilts

Eukaryotic Cell Organelles and Function Chloroplast Function: Photosynthesis! makes glucose for the plant cell Green in color because of chlorophyll, which is a green pigment

Eukaryotic Cell Organelles and Function Cell Wall Function: provides support and protects cell membrane Made of cellulose Found outside the cell membrane in plant cells
