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:

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
