1. NUCLEUS Information and administrative centre of the cell
Surrounded by a double membrane
Control centre for metabolism and reproduction
Contains genetic information in the form of DNA which is the subunit of genes found on chromosomes
Surrounded by the nuclear membrane which contains pores which control the passage of substances in and out of the cell
Contains the nucleoli which are densely composed of DNA, RNA, and protein
The nucleoli are the sites of the production of ribosomes

4. ENDOPLASMIC RETICULUM
Network of sacs that manufactures, processes, and transports chemical compounds for use inside and outside of the cell
It is connected to the double layered nuclear envelope, providing a connection between the nucleus and the cytoplasm

6. CHLOROPLAST Found in photosynthetic protists, bacteria, and plants
Site of photosynthesis
Converts radiant energy into chemical energy
Requires CO2, light, and water
Produces sugar, O2

8. MITOCHONDRION Oblong shaped organelles
Power generators that convert oxygen, glucose, and other nutrients into usable energy
The by-products of this series of reactions called cellular respiration are CO2, water, and ATP (the energy storage molecule)
Folded inner mitochondrial membrane provides a greater surface area for more biochemical reactions

9. Mitochondria
cristae

10. GOLGI COMPLEX
Distribution and shipping department for the cell’s chemical products
Modifies proteins and fats built in the endoplasmic reticulum and prepares them for export to the outside of the cell

11. Golgi Bodies

13. CENTRIOLES
Self-replicating organelles made up of nine bundles of microtubules
found only in animal cells
Help organize cell division (mitosis/meiosis) but aren’t essential to the process

15. CILIA and FLAGELLA
For single-celled eukaryotes, cilia are essential for the locomotion of individual organisms
In multi-cellular organisms, cilia function to move fluid or materials past an immobile cell as well as moving a cell or group of cells

17. Ciliates:
Didinium ingesting
Paramecium

18. FLAGELLA
Sperm use flagella to propel themselves toward the egg

19. LYSOSOMES
Digestion
Break down cellular waste products and debris from outside the cell into simple compounds
These compounds are
transferred to the cytoplasm
as new cell-building
materials

20. RIBOSOME Constructed of RNA and protein
Site of the production of proteins with the help of the genetic blueprints provided by the DNA in the nucleus
Protein strand

21. -Outer wall of plant cells
-Made of cellulose for support

22. Vacuole -found in both plant and animal cells
-50-70% volume of a plant cell (support)
