1. Structure and Function of Cells

2. Cell Membrane Outer Shell of the Cell
Separates the cell from the external environment
Regulates what comes into and out of the cell
Security system of the cell

4. Cytoplasm Jelly Like mixture
Contains molecules and small cell parts(organelles)
Contains enzymes to drive chemical reactions

6. DNA Long molecule containing information Controls cells activities
Mutations can cause irregular cell division
Complex instructions

8. Nucleus Controls cells activities Stores DNA Large, Round/Oval Shape
Is made up of the following parts:
Nuclear Membrane
DNA
Nucleolus
In both Plant and Animal Cells

9. Nuclear Membrane Surrounds Nucleus Selectively Permeable
Controls what moves into and out of the nucleus
Both Plant and Animal Cells

10. Nucleolus Found inside the nucleus Creates Ribosomes
Both Plant and Animal Cells

12. Mitochondrion (Mitochondria)
Bean shaped with inner membranes
Breaks down sugar molecules into energy
Both Plant and Animal Cells

14. Ribosome
Small bodies that are free within the cell or attached to E.R.
Produce Proteins
Created by the Nucleolus
Both Plant and Animal Cells

16. Endoplasmic Reticulum (ER)
Network of tubes or membranes
Carries materials through the cell
Smooth and Rough ER
Rough ER have Ribosome attached
Both plant and animal cells

18. Vacuole Fluid-filled sacs Store food, water, waste
Plants store large amounts of food, have large vcacuoles
Both Plant and Animal Cells

20. Golgi Bodies Packages proteins for transport Tubes and membranes
Thought of as UPS or Post Office of the cell

22. Lysosome Small, round with a membrane
Breaks down larger food molecules into smaller pieces
Digests old cell parts
Uncommon in Plants, common in Animal Cells

24. Plant Cell Parts Parts that are common only in Plant cells include:
Cell Wall
Chloroplast
Chlorophyll

25. Cell Wall Outer Layer of Plant Cell Rigid, strong Made of cellulose
Provides Support, Protection
Allows H2O, O2, CO2 to pass into and out of cell

27. Chloroplast Green, oval
Uses energy from sun to make food for the plant
Contain Chlorophyll

29. Chlorophyll Very small, round, green Provide pigment to the plant
Used during photosynthesis
