1. Eukaryotic Cell Structure and Function Animal and Plant Cells

2. Essential Questions How does a cell function?
How do materials the cell needs get into the cell?
What are the 3 most important organelles and what do they do?

3. Eukaryotic Cell Structure
Cell membrane – membrane around cell; separates outer from inner.
Nucleus – structure that houses DNA
Organelles – structures that carry out specific jobs for cell.
Cytoplasm – jelly-like fluid where the organelles “float.”

4. Cytoskeleton Cytoskeleton –protein filaments
( microtubules) in cytoplasm.
helps maintain cell shape, cell move,& moves organelles.
help with cell division

5. Inside the Nucleus Nuclear Envelope – membrane that surrounds nucleus.
Chromatin –DNA wrapped around proteins.
Chromosomes – condensed chromatin (DNA), condenses before cell division.
Nucleolus – structure within nucleus that makes ribosomes.

6. Inside the Nucleus Nucleolus Chromatin Nuclear Envelope

7. Ribosomes Ribosomes – made of RNA and protein. Make Proteins!

8. Vesicle Small, membrane-bound sac that transports substances in cells
Some become lysosomes

9. Lysosomes Lysosomes – small organelles filled with enzymes.
Digest molecules and old cell parts used by cell

10. Endoplasmic Reticulum (ER)
Endoplasmic reticulum – organelle that moves proteins and other substances.
Rough ER – has ribosomes, makes proteins
Smooth ER – no ribosomes, makes lipids, and breaks down toxins

11. Golgi Apparatus
Golgi Apparatus (Body)– modifies, sorts, and packages proteins.
like UPS

12. “Power House of the Cell”
Mitochondria
“Power House of the Cell”
Mitochondria – converts chemical energy stored in food into compounds that cell can use better.
Makes energy (ATP).
Has own DNA

13. Plant Cells – 3 features Animal cells don’t have.

14. Central Vacuole
Central Vacuole – large, space; stores water and other substances such as ions, nutrients, and wastes.

15. Chloroplasts
Chloroplasts – organelles that capture light energy from sun and convert it into chemical energy. (Photosynthesis)
Found only in plants, algae, and some bacteria.
Has own DNA.

16. Cell wall
Cell Wall - structure surrounding cell membrane; provides structure and shape.
composed of proteins, carbs, and cellulose (sugar)
protects from damage and connects it to next cell

17. Animal Cell vs. Plant Cell

18. Activities Make foldable of plant and animal cell.
Must have drawing of both animal and plant cells.
Must be colored and labeled.
Must have venn diagram comparing cells.
Label all organelles on both cells.
Will tape into spiral
