What are three differences between plant & animal cells?

3. Plant cells have a cell wall. Animal Cells do not.
Plants vs. Animals
There are three main differences between plant and animal cells:
Plant cells have a cell wall.
Animal Cells do not.

4. 2. Plant cells have chloroplasts and Animal Cells do not.

6. Organelles What Is An Organelle?
Organelles = little organs that perform specific jobs in the cell
Organelles are found in eukaryotic cells but not prokaryotic cells.
Plant and Animal cells are both examples of eukaryotic cells with organelles
Plant and Animal cells contain many of the same organelles, but there are several differences (mentioned in today’s bell- work)

7. Nucleus Job: Controls the Cell
Contains DNA with coded instructions for cell functions.
In a Factory- Boss

8. Nuclei contain:
Nucleolus- a small, dense region where the assembly of ribosomes begins.
Nuclear envelope- The nucleus is surrounded by a nuclear envelope composed of two membranes. These membranes have nuclear pores which allow materials to move into and out of the nucleus.

9. Mitochondria Looks like: a bean
Job: powerhouse of the cell-it produces the energy in the form of ATP
In a factory: generator
(energy source)

10. Mitochondria

11. Ribosomes
Looks like: Small particles of RNA in the cytoplasm and on the ER
Job: make proteins (protein synthesis)
In a factory: workers

12. Endoplasmic Reticulum
Looks like: internal membrane system next to the nucleus (rough ER has ribosomes, smooth ER does not)
Job: transports materials
Synthesize proteins/ enzymes
In a factory: conveyor belt

13. Smooth ER & Rough ER
Smooth ER- Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids.
Rough ER- Rough ER (RER) is very important in the synthesis and packaging of proteins. Ribosomes are attached to the membrane of the ER, making it “rough.”

14. Golgi Apparatus Looks like: stack of membranes
Job: Packs, sorts, and ships proteins & other materials
In a factory: packaging center

15. Cell Membrane (Plasma Membrane)
Looks like: layered
membrane (called a lipid
bilayer) surrounding the
cell but inside of the cell wall
Job: “the regulator”
-controls what comes in and
out of the cell, protects, and supports the cell
In a factory: security guards

16. Cell Wall Looks like: thick layer outside the plasma membrane
Job: structure and support
In a factory: Cement wall

17. Lysosome Looks like: small, sac-like organ Job: breaks down wastes
In a factory: recycling center

18. Chloroplast
Looks like: green stacks of membranes the contain chlorophyll
Job: perform photosynthesis (convert sunlight into energy)
In the factory: greenhouse

19. Vacuole Looks like: sac-like organ. HUGE in plant cells
Job: stores water, food, and waste
In a factory: storage room

20. Centrioles Centrioles are made of microtubules.
Job: They play a central role in organizing cell division.

21. Cytoplasm
The cytoplasm is the portion of the cell outside of the nucleus.
Material in the cell membrane (not including the nucleus).

22. Organelle Function
Nucleus: Contains the DNA and RNA and manufactures proteins
Nucleolus: In nuclei where ribosomes are synthesized.
Nuclear Envelope: Membrane of lipids and proteins that surrounds nucleus
Centrioles: structure that appears during mitosis(cell division)
Mitochondria: Energy producers of the cell
Ribosomes: Produce proteins

23. Organelle Function Golgi Bodies: Packages Proteins
Chloroplasts: Involved in photosynthesis
Vacuoles: Store waste, nutrients, and water
Lysosome: Contains digestive enzymes, mostly in animal cells.
Endoplasmic Reticulum: Passageway that transports proteins from the nucleus
Rough ER is covered in ribosomes, Smooth ER is not!
