2. Golgi Apparatus
Definition- distribute and modify materials for cell use
Package organelle
Found in most plant and animal cells
Animal cells have fewer and larger Golgi apparatus’
Plant cells contain many and a smaller version
It is a group of flattened disc-like structures located close to the Endoplasmic Reticulum.

3. Golgi Apparatus FUNCTION
It transport, modify, and packaging proteins and lipids into vesicles
It builds lysosomes
It builds sugar and sends it off to the cell

4. Golgi Apparatus- Why it’s Important
producing chemicals such as pectin and polysaccharides which is used in making the cell walls.
It is the only organelle in the cell that receives, sorts, modifies, concentrates, packs and despatches biochemicals for use inside and outside the cell.
In specialist secretory cells the Golgi complex is responsible for the sorting and packing of such well-known items as insulin, digestive enzymes and pectin.

5. Vacuoles
Storage bubbles found in cells. They store any variety of nutrient a cell needs to survive as well as waste products, which protects the entire cell from contamination. Vacuoles help plants maintain their shape.

6. Lysosomes
Definition- a membrane bounded vesicle that contains digestive enzymes
produced by the golgi apparatus
part of the endomembrane system
found in all eukaryotic cells
the breakdown of structures within the cell
Lysosome has a single membrane with a sphere shape
the interior of the lysosome is acidic

7. Lysosomes FUNCTION Lysosomes are a part of the cell that:
Digests food (digestive enzymes)
inside & outside cell
Destroys waste and cleans up cell
Destroys worn-out or damaged organelles
Protects from invaders
*Many times lysosomes recycle the materials that are brought into the cell (biosynthesis)

8. Lysosomes- Why it’s Important
Breakdown complex molecules
either digest this material or recycle it
It is able to digest useless materials on the inside and outside of the cell and create usable nutrients
Without effective lysosomes the body may have diseases
lysosomal storage disease- accumulation of undigested substances
New organelles depend on the lysosome

9. Peroxisomes
Definition- a type of microbody that contains oxidative enzymes and catalase
found in almost all eukaryotic cells
they are able to self-replicate however they do not have their own internal DNA molecules
Location- scattered throughout cytoplasm
The peroxisome is a
sphere shape and bound by a single membrane.

10. Peroxisomes
FUNCTION
Example- oxidization (loss of an electron or molecule by an atom)
Primary function- making their enzymes function together to rid the cell of toxic substances
hydrogen peroxide (H2O2) changes into water (H2O) and oxygen (O2)
peroxisomes primarily focus on enzymes that require oxygen
They are known for digesting fatty acids and alcohol

11. Peroxisomes- Why it’s Important
It is a catalyst which means that is speeds up reaction rate by lowering activation energy
If you don't have enough you won't be able to break down fatty acids which can lead to many fatal diseases
Zellweger Syndrome: Fatty acids cannot be broken down leading to brain damage and death
*the peroxisome is a key factor in many basic functions throughout plants and animals
