1 Rough ER Transport vesicle from ER Golgi apparatus Secretory vesicle from Golgi Secretory protein Vacuole Lysosome Plasma membrane The Endomembrane System

2 The Golgi Apparatus –Works in partnership with the ER –Refines, stores, and distributes the products of cells Transport vesicle from ER “Receiving” side of Golgi apparatus New vesicle forming Transport vesicle from the Golgi “Shipping” side of Golgi apparatus Plasma membrane

3 A lysosome is a membrane-enclosed sac Lysosomes – It contains digestive enzymes –The enzymes break down macromolecules –They break down damaged organelles (b) Lysosome breaking down damaged organelle Lysosome Damaged organelle Digestion

4 Vacuoles Vacuoles are membranous sacs

5 Mitochondria are the sites of cellular respiration, which involves the production of ATP from food molecules Figure 4.18 Outer membrane Inner membrane Cristae Matrix Space between membranes Cellular energy conversion

6 Cytoskeleton ● Provides mechanical support to the cell and maintain its shape

7 The Cytoskeleton *microfilaments (actin filaments) *intermediate filaments *microtubules

8 Microfilaments

9 Microtubules *centrosome *centrioles

10 Cilia and flagella are motile appendages Cilia and Flagella Flagella propel the cell in a whiplike motion Cilia move in a coordinated back-and-forth motion

11 “9 + 2” basal body Cilia and Flagella

12 The Cytoskeleton dynein – motor molecules

13 Cytoskeleton Mitochondrion Nucleus Rough endoplamsic reticulum (ER) Ribosomes Smooth endoplasmic reticulum (ER) Golgi apparatus Plasmodesmata Plasma membrane Chloroplast Cell wall Central vacuole Not in animal cells Plant Cells

14 Plant cells are encased by cell walls Walls of two adjacent plant cells Vacuole Plasmodesmata (channels between cells) Plant Cells

15 Chloroplasts are the sites of photosynthesis, the conversion of light energy to chemical energy Chloroplasts Inner and outer membranes of envelope Space between membranes Stroma (fluid in chloroplast) Granum

16 Origin of Eukaryotes
