Discussion:

3. Chapter 2 “Cells” Section 1: “Cell Structure Pages 38 – 40
LESSON 1

4. COMMON CELL TRAITS
A cell is the smallest unit that is capable of performing life functions.

5. COMPARING CELLS
The size & shape of a cell relates to its function. (job it does)

6. Prokaryotic Cells (proh KAYR ee yah tihk)
cells without membrane-bound structures
EX: bacteria
pond scum

7. Eukaryotic Cells (yew KAYR ee yah tihk)
cells with membrane-bound structures
EX: animals, plants, fungi and protists

8. CELL WALL protects the cell gives shape is made of cellulose
A cell wall is found in plants, algae, fungi, & most bacteria.

9. CELL MEMBRANE Outer covering, protective layer around ALL cells
For cells with cell walls,the cell membrane is inside the cell wall
Allows food, oxygen, & water into the cell & waste products out of the cell.

10. CYTOPLASM gelatin-like inside cell membrane constantly flows
aka protoplasm

11. NUCLEUS Directs all cell activities
Contains instructions for everything the cell does
These instructions are found on a hereditary material called DNA
Usually the largest organelle

12. CHLOROPLASTS
Green organelles that make food
found only in plant cells

13. CHLOROPHYLL A green pigment that gives leaves & stems their color
Captures sunlight energy that is used to produce food called glucose
Glucose is a type of sugar

14. MITOCHONDRIA Organelles that release energy from food

AKA the powerhouse b/c they release energy from food
Some muscle cells have 20,000 mitochondria
