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 complex,
but with differences.

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

6. Organization of Structure of Multi-celled Organisms
ORGANS SYSTEM
ORGAN
TISSUE
CELL
ORGANELLE

7. Life Functions Nutrition – to get nutrients for energy
Transport – to move materials from A to B
Cell respiration – Energy: ATP
Excretion – to get rid of metabolic waste
Synthesis – to build, to make
Regulation – to control
Growth – to increase in size or number
Reproduction – to make offspring

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

9. TRANSPORT CELL MEMBRANE FUNCTION: Provides boundary of the cell.
Controls what comes in and out.

10. TRANSPORT CYTOPLASM FUNCTION:
To protect and support the organelles within the cell.
Aids in transport within cell
TRANSPORT

11. *REGULATION *Synthesis *Reproduction NUCLEUS
Found in eukaryotic cells only!
Function: Controls most cell processes and contains the hereditary information - DNA
*REGULATION
*Synthesis
*Reproduction

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

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

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

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

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

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

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

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

20. SUPPORT & PROTECTION CELL WALL FUNCTION:
Provides support and protection for the cell and allows materials in and out of the cell.
FOUND IN PLANT CELLS.
SUPPORT & PROTECTION

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