Q

Mitochondrion

A

The amount of it in a cell is related to the amount of energy production in the cell
Produces energy through cellular respiration
ATP=Energy
Has two membranes
Energy production takes place in the interior membrane
Cristae are folds that increase surface area of the interior membrane
Contains own DNA and ribosomes

Q

Vesicle

A

What the protein is transported in from the Golgi body

17
Q

Nucleolus

A

Produces ribosomes

18
Q

Lysosomes

A

Contains hydrolytic enzymes used to break things down
Digests macromolecules and worn out organelles
When a cell must die,, lysosomes release the hydrolytic enzyme
“Cleaning crew”

19
Q

Centrioles

A

Used in cell replication. Only in animal cells

20
Q

Why are cells so small

A

Because the parts of the cell are incredibly slow moving

21
Q

Vacoules

A

Stores food and waste product of the cell
Multiple small ones
Attached to the membrane

22
Q

The cytoskeleton

A

fibrous network in the cytoplasm
provides mobility, support, and biomechanical regulation
Composed of three types of fibers
Microtubules
microfilaments
intermediate filaments

23
Q

Centrosome

A

Region near nucleus contains centrioles
