A&P lecture ch 3.

cell structure and function

non membranous organelles

SIX TYPES

1. cytoskeleton

2. microvilii

3. centrioles

4. cilla

5. ribosomes

6. proteasome

cytoskeleton

microvilli

centrioles

cilia

ribosomes

two types:

-free ribosomes in cytoplasm (inside cell)

-fixed ribosomes attached to ER (outside cell)

proteasome

membranous organelles

endoplasmic reticulum (ER)

-cisternae are storage chambers within membranes

-endo=withn, plasm=cytoplasm, reticulum=network

smooth endoplasmic reticulum (SER)

-no ribosomes

-sythnesizes lipids and carbohydrates

rough endoplasmic reticulum (RER)

golgi apparatus

lysomes

peroxisomes

mitochondria
