1. Aim: How can we describe the structure and function of cell organelles?

2. ORGANIZATION CHART
BACTERIA

3. Prokaryotes All Bacteria They DO NOT have membrane bound organelles.
They DO have:
Cell Membranes
Cell Walls
DNA
Ribosomes

4. 2 Types of Eukaryotic Cells:
Animal Cell
Plant Cell
Both are complex, but there are differences

5. What are those things inside the cell?
Organelles- Specialized structures in cells that perform important cellular functions.

6. Life Functions Nutrition – to take in food
Transport – to move materials
Cell respiration – Make Energy: ATP
Excretion – to get rid of waste
Synthesis – to build, to make
Regulation – to control
Growth – to increase in size
Reproduction – to make offspring

7. Do Now
Define:
Homeostasis
Cellular Respiration

8. Aim: What are the various functions of an organelle?

9. TRANSPORT CELL MEMBRANE Barrier to protect the cell.
FUNCTION:
TRANSPORT
Barrier to protect the cell.
Controls what comes in and out.

10. CELL WALL REGULATION FUNCTION:
Provides support and protection for the cell and allows materials in and out of the cell.
FOUND IN PLANT CELLS.
REGULATION

11. Makes energy or ATP from food and oxygen.
MITOCHONDRIA
FUNCTION:
RESPIRATION
Powerhouse of the cell.
Makes energy or ATP from food and oxygen.

12. CYTOPLASM TRANSPORT FUNCTION:
To protect and support the organelles within the cell.

13. ENDOPLASMIC RETICULUM
FUNCTION:
Transportation route of cell. Materials travel through it.
2 Types: Rough ER (has ribosomes) & Smooth ER
TRANSPORT

14. GOLGI APPARATUS TRANSPORT
FUNCTION:
TRANSPORT
Proteins from ER come here. Labels and packages the proteins, gives them a direction to follow.

15. RIBOSOMES SYNTHESIS FUNCTION: They FORM proteins
Can be found in cytoplasm or on Endoplasmic Reticulum (Rough)

16. VACUOLES
FUNCTION:
Store materials such as water, salt, proteins, and carbohydrates.
MANY SMALL ONES IN ANIMAL CELLS, AND ONE BIG ONE IN PLANT CELLS.
EXCRETION

17. CHLOROPLASTS SYNTHESIS FUNCTION:
Use energy from sunlight to make energy-rich food molecules in a process known as PHOTOSYNTHESIS
FOUND IN PLANT CELLS!

18. CENTRIOLES REPRODUCTION FUNCTION: FOUND ONLY IN ANIMAL CELLS
Involved in animal cell division
FOUND ONLY IN ANIMAL CELLS

19. REGULATION NUCLEUS Found in eukaryotic cells only!
Function: Controls most cell processes and contains the hereditary information - DNA (THE BRAIN)
REGULATION
THE BRAIN

20. LYSOSOMES NUTRITION FUNCTION:
Contain enzymes that can break down nutrients. Also they break down dead organelles.

21. CILIA & FLAGELLA NUTRITION FUNCTION:
Made of protein and help with the movement of individual cells
NUTRITION
