5. A Review of the Cell Organelles
Anatomy of the animal cell

6. Animal Cell Organelles
Nucleus
Nuclear envelope, nuclear pores, chromatin, nucleolus
Ribosomes
Endoplasmic Reticulum
Rough and smooth
Golgi Apparatus
Mitochondria
Lysosomes
Peroxisomes
Cytoplasm
Plasma membrane
Cytoskeleton
Vacuoles
Smaller than plant
Centrioles (2)

7. Plant Cell Organelles Nucleus Ribosomes Endoplasmic Reticulum
Nuclear envelope, nuclear pores, chromatin, nucleolus
Ribosomes
Endoplasmic Reticulum
Rough and smooth
Golgi Apparatus
Mitochondria
Lysosomes
Peroxisomes
Cytoplasm
Cytosleton
Plasma membrane
Cell wall
Vacuoles
Larger than animal
Chloroplast

8. Nucleus “the control center”
Four parts:
Nuclear Envelop
Nuclear Pores
Chromatin
Nucleolus
Function:
Holds DNA (genetic information)
Directs cell activities

9. Nuclear Envelope and Nuclear Pores
Nuclear Envelope: separates nucleus from cytoplasm
Nuclear Pores: allows mRNA to go in and out of the nucleus

10. Chromatin and Nucleolus
Chromatin: strands of DNA that coil together to form chromosomes during cell replication
Nucleolus: Where the rRNA is produced

11. Endoplasmic Reticulum “roads”
Manufacturing and shipping of “goods” Continuous with the nuclear envelop
Smooth ER
Rough ER
No ribosome's
Makes lipids (fats)
Have Ribosome's
Makes proteins

12. Ribosomes “PROTEIN!!” Makes PROTEINS Made of rRNA and PROTEIN
Thousands in each cell
Location
Bound: On Rough ER
Free: Floating around cell

13. Lysosomes “clean up crew”
Peroxisomes
“detoxifier”
Circular, bigger than ribsomes
Break down food into particles that the cell can use
Destroy old cells
Transport undigested material to cellular membrane to be removed
Circular, about the same size as lysosome
Break down lipids into fatty acids that can be used by the cell
Detoxify alcohol in liver
Produce and break down hydrogen peroxide

14. Mitochondria “the powerhouse” Vacuole “storage bin”
Form energy by breaking down food to make ATP (energy)
ATP: fuel for cell activities
Not bound by a membrane
Store, digest, and remove waste.
Contains water solution
MUCH smaller in an animal than a plant

15. “scaffolding and skeleton”
Cytoskeleton
“scaffolding and skeleton”
Golgi Apparatus
“the shippers”
Provides the cytoplasm with structure and shape
Three types:
Filaments
Microfilaments
Microtubules
Looks like a stack of pancakes
Protein ‘packaging plant’
Move materials within and out of the cell

16. Cytoplasm Cell Membrane
Gel like mixture
Surrounded by the cell membrane
Contains genetic information
Controls the movement of substances in and out of the cell
A lipid bilayer

17. Animal Cell ONLY Smaller Vacuoles Centriole
Involved in the organization of the mitotic spindle
Completion of cytokinesis

18. Plant Cell ONLY Larger vacuole Chloroplast Cell Wall Green in color
Not bound by a membrane
Converts sunlight energy to chemical energy
Outer layer that protects cell
Maintains shape
Made of cellulose

19. Which cellular structures are involved in synthesizing and packaging protein?
1 packages protein, and
3 synthesizes protein.
4 synthesizes protein.
2 packages protein, and

20. Lets Review! Plants Animals
List the differences between plant and animal cells.
Plants
Animals
