1. Eukaryotic Cell Structures & Functions
Ch7.3 (Ch7 Vocabulary Guide)

2. An Organelle Is:
A minute structure within a plant or animal cell that has a particular job or function.

3. What are some functions that occur within a cell?
Digestion Excretion
Transportation of cell’s products
Storage Protection
Division Mobility
Respiration or Photosynthesis

4. Organelles found only in Plants:
Cell Walls
Cellulose
Chloroplasts

5. Plant Cell Cellulose = carbohydrate found in cell walls
Cell Wall= forms rigid outer structure, made of cellulose (fiber)

6. Cell wall
Chloroplast
Large vacuole
PLANT CELL

7. Found in both Plant and Animal Cells
Organelles that surround cells for support:
Cell Membrane= Semi-permeable,
controls what enters and leaves the cell, outer containment envelope.
Cytoskeleton =
gives structure to a cell (#14)

9. Nucleus
Cell
Membrane
ANIMAL PLANT

10. Control center for plant and animal cells:
This organelle controls cell activities and reproduction

11. Nucleus
Nucleolus=
“little nucleus”
Animal Cell

12. Control center for plant and animal cells:
Nucleus = control center for activities & reproduction, DNA & chromosomes housed here.
Nucleolus = contains and makes RNA

13. Control center for plant and animal cells:
Chromosome = coiled DNA: contains instruc-tions for char-acteristics of an organism.
Chromatin = protein composing chromosomes

14. Red Blood Cells have no:
nucleus

15. Control center for plant and animal cells:
Nuclear membrane = protects and controls what goes in and out of the nucleus
(notice the nuclear pores in this picture of a nucleus)

16. Ribosomes= Site of Protein Synthesis on the E.R.
Endoplasmic Reticulum
ROUND Ribosomes

17. Cytoplasm:or cytosol, = gel surrounds the organelles, contains enzymes

18. ER = Endoplasmic Reticulum:
specializes in the production & transport of lipids and membrane proteins
Rough ER has ribosomes Smooth ER lacks ribosomes
Ribosomes: Where proteins are manufactured.

19. Endoplasmic Reticulum
“Rough” with Ribosomes
for protein synthesis
“Smooth” =
Membrane “highway”
For transport of materials

20. Golgi Bodies (aka Golgi Apparatus):
where cell products are modified and packaged in vesicles for export from the cell.
“Sacks” for making
& storing Secretions

21. Vacuole = storage for food and water Why are plant vacuoles larger than animal vacuoles?

22. Do you see 2 Contractile vacuoles
Some Animal cell vacuoles pump water out by contracting:
Do you see 2 Contractile vacuoles
in this Paramecium?

23. Lysosome:
Contains digestive enzymes
Breaks down large molecules

24. Chloroplast= absorbs light, changes light energy into chemical energy for photosynthesis = GREEN Sacks

25. The power house of the cell:
Mitochondria = site where energy is released from glucose in the form of:
ATP
