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

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

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

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

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

7. PLASMA 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.

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

9. CYTOSKELETON scaffolding-like structure in cytoplasm
helps the cell maintain or change its shape
made of protein

10. 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

11. NUCLEAR MEMBRANE separates nucleus from cytoplasm
controls movement of materials in & out of nucleus

12. NUCLEOLUS Aka “little nucleus” Found in the nucleus
Ribosomes made here

13. CHROMATIN contains genetic code that controls cell
made of DNA & proteins (deoxyribonucleic acid)

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

16. 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

17. MITOCHONDRIA Organelles that release energy from food
This energy is released by breaking down food
into carbon dioxide
AKA the powerhouse b/c they release energy
from food
Some muscle cells
have 20,000 mitochondria

18. RIBOSOMES Make proteins
Float freely or attached to the endoplasmic reticulum (ER)
Ribosomes are made in the nucleolus

19. ENDOPLASMIC RETICULUM
A series of folded membranes that move materials (proteins) around in a cell
like a conveyor belt
Smooth ER – ribosomes not attached to ER
Rough ER – ribosomes attached to ER

20. GOLGI BODIES (GAWL jee)
Stacked flattened membranes
Sort and package proteins

21. VACUOLES
Temporary storage spaces
Store food, water, waste

22. LYSOSOMES (LI suh sohmz)
The word "lysosome" is Latin for "kill body."
The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies.
Break down food molecules, cell wastes & worn out cell parts

23. FROM CELL TO ORGANISM Tissue Group of cells working together
Group of tissues working together
Organ System
Group of organs working together
Organism
Any living thing made of 1 or more cells

24. NAME THE ORGANELLE a. Nucleus c. Golgi body b. Chloroplast
d. Mitochondria
