1. Cell Organelles

2. Centrioles A pair of small cylindrical structure
Composed of microtubules
Involved in the separation of chromosomes during cell division in animal cells and protists
Not found in plant cell

3. Chloroplast Definition Image
Found in some plant cells (green organelle)
Photosynthesis takes place
Composed of many folded layers of membrane

4. Cytoplasm the contents of a cell It is more than 90% water
Contain ions, salts enzymes, food molecule and other organelles other than the nucleus.

5. Cytosol The fluid component of cytoplasm
In which organelles are located

6. Endoplasmic Reticulum
It is where, where most reactions takes place
The cell makes lipids and other chemicals,
it sometimes has ribosomes attached.
Involved with the production , processing, transport, and storage of materials with the cell
Image

7. Golgi Apparatus
image
essential in packaging different products from the endoplasmic reticulum and the ribosomes into their final form.

8. Lysosomes Image membrane- bound vesicles
Containing powerful enzymes that breakdown debris and foreign material
Found in most animal cell

9. Mitochondria Image Composed of many unfolded layers of membrane
Involved in the energy transformation that release energy

10. Nucleus Image Large organelle
The nucleus is the control centre of the cell
dictates what all of the other organelles do.
The nucleus also stores the DNA.

11. Plasma Membrane Image Encloses the cytoplasm in all cells
Controls the movement of substances into and out of the cell
Responsible for recognition, adhesion and chemical communication between cells

12. Plastids Found only in plant cells
Which develop from simple organelles called proplast
Plastids include chloroplast, amyloplasts & chromplast(contain colour pigments)

13. Ribosomes The nucleus is the control centre of the cell Image
dictates what all of the other organelles do.
The nucleus also stores the DNA

14. Tonoplast Vacuole membrane in plant cells Image
Regulates the movement of substances into and out of the vacuole.
Image

15. Vacuole found in most cells
Plant cells: have large fluid filled vacuole
Containing cell sap which support physical support through turgidity and storage
In other cells vacuole maybe involved in intracellular digestion or water balance

16. Vesicles Membrane –bound organelles
Often associated with transport in cell

17. Cell wall Found only in PLANT cells Gives support to the cell
Is a second layer or “fence” like the cell membrane.

18. Cytoskeleton Location: All cells
Description: Made of microtubules - microfilaments
Function: Strengthen cell & maintains the shape
Moves organelles within the cell
