Term
nonmembronous organelles
Definition

-cytoskeleton

-centrioles

-cilia

-flagella

-ribosomes

Term
microfilaments
Definition

-tiny rods of actin

-helps give the cell shape

Term
microtubules
Definition

-made of tubulin

-stiffer, help to maitain the shape

-helps move organelles within the cells

Term

centrosome

(centriole)

Definition

-microtubule organizing center

-near golgi and nucleus

-2 hollow cylinders; lay at right angle

-made of 9 microtubules

-function is to separate chromo. during cell repro.

Term
cilia
Definition

-tiny, hairlike, attched to the basal body

-arranged in rows

-respiratory tract

 

Term
flagella
Definition

-only one per cell

-sperm

Term
ribosomes
Definition

-made of rRNA and protein

-found in rough er and in free cytoplasm

-function=protein synthesis

mitochondria
Definition

-powerhouse of the cell

-oval shaped

-produces ATP

-can self replicate

 

Term
golgi apparatus
Definition

-refines, packages and delievers proteins

-recieves proteins from ER

Term
endoplasmic reticulum
Definition

-transport system for molecules in the cell

-rough ER

   -coated with ribosomes

   -protein synthesis

-smooth ER

   -no ribosomes

   -lipid synthesis

Term
lysosomes
Definition

-garbage disposals

-contain digestive enzymes

-function= digest bacteria and toxins, degrade worn out cell parts ans break non useful fetal tissue

Term
peroxisomes
Definition

-detoxify harmful substances

-break down lipids

-get rid of free radicals

-look like lysosomes

-most abundant in liver an kidneys
