1. CELLS LESSON
Enduring Understanding: Cells have distinct and separate organelles which perform all the life functions for their survival.

2. Cell Major Understandings
Explain how cells are designed to perform specific jobs.
Given a diagram of a cell identify and describe the function of the given organelles.
List and compare how structures present in some single celled organisms act in a manner similar to tissues and systems found in multicellular organisms.
How an organism functions at the cellular level to maintain homeostasis.

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

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

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

6. 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.
Regulates what enters and leaves the cell.

7. CYTOPLASM gelatin-like inside cell membrane
constantly flows (cyclosis)
aka protoplasm
Site where most chemical reactions take take place

8. 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

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

10. NUCLEOLUS Aka “little nucleus” Found in the nucleus
Makes the ribosomes

11. CHROMATIN contains genetic code that controls cell
made of DNA & proteins

12. RIBOSOMES Make proteins Site of protein synthesis
Float freely or attached to the endoplasmic reticulum (ER)
Ribosomes are made in the nucleolus

13. CHLOROPLASTS Green organelles that make food (sugar)
found only in plant cells

14. 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

15. MITOCHONDRIA Organelles that release energy from food (respiration)
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

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

17. 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

18. 1- Nucleus
2- Chromosomes
7- ER
3- Mitochondria
5- Chloroplasts
8- Cell Membrane
4- Ribosomes
6- Vacuoles
