chapter 4
eukaryotic cell organelles
semiautonomous organelles
mitochondria (make ATP)
chloroplasts(photosynthesis)
cytosol
cytoskeleton
microtubles
actin filaments
intermediate filaments
endomembrane system
lysosomes (contain acid hydrolases that break down organic molecules under acidic conditions , endocytosis for substances from outside, autophagy
vacuoles (central vacuoles for storage and support, contractile vacuoles for expelling excess water, phagocytic for degradation )
golgi apparatus
secretion, protein sorting, processing
nucleus(material within it are not part of endomembrane system
ER
rough ER (studded with ribosomes , protein synthesis and sorting)
smooth ER (lacks ribosomes, detoxification, Ca balance, phospholipids synthesis and modification)
peroxisomes (catalyze hydrolysis reaction)
plasma membrane (transport, cell signaling, cell adhesion)
cell theory
cells are the smallest units of life
new cells come only from pre existing cell division
all living organisms are composed of one or more cell
