2. Structures not in common –
What are the 3 plant “extras”?

Common Structures in Animal and Plant Cells

Common Structures in Animal and Plant Cells.

3. A Plant Cell Has:
Cell wall
Chloroplasts
Central vacuole

4. D. Plant Organelles Plastids Site of photosynthesis
Plant makes its own food from sunlight
Contain colored pigments
Chlorophyll in chloroplasts is green
Have their own DNA and ribosomes

5. Cell walls
Rigid
Allow trees to grow tall
Made of Cellulose

6. Central Vacuole Central Vacuole Acts as water storage for plants
Contains:
Wastes
Food
Digestive enzymes
Takes up most of the plant cell’s volume
Central Vacuole

7. E. Cytosol Non-living fluid in cells Cytoplasm Like half jelled Jell-o
= Cytosol + Organelles

8. F. Cytoskeleton Cell’s “structure” Functions Cell shape
Moving organelles around
Cell locomotion
Cillia & Flagella
Similar to an outboard motor

9. F. Cytoskeleton Three Tubule types Microfilaments Intermediate fibers
Microtubules

10. G. Plasma Membrane Cell’s “Security Gate” Made of Phospholipids
Selectively Permeable
Allows only some things to pass through
Made of Phospholipids
Surrounds animal and plant cells

11. H. Origin of Organelles Endosymbiote theory Lynn Margulis
Proposed by Lynn Margulis
For Mitochondria and Plastids
Ribosomes and DNA look like what’s in bacteria.
They may have been bacteria
Moved in to larger cells to cooperate
