Cell Organelles Flashcards
nucleus
genetic control center of cell
directs protein synthesis
houses DNA
nuclear pores
regulate molecular traffic through envelope
holds two membranes together like screw
plasma membrane
contains cell contents
regulates exchange of materials
involved in intracellular comm.
ribosomes
interpret the genetic code
synthesize polypeptides
smooth Er
lipid synth.
detoxification
calcium storage
transports proteins
rough ER
protein synthesis
manufacture cellular membrane
Golgi apparatus
receives and modifies new polypeptides
synthesizes carbohydrates
packages cell products
lysosomes
contain enzymes for intracellular digestion, programmed cell death and glucose mobilization
peroxisomes
contain enzymes for detoxification: for drugs, alcohol and free radicals
mitochondria
ATP synthesis
aerobic respiration
cytoskeleton
structural support
splits chromosomes during cell division
organelle trafficking
microtubules
hold organelles in place
maintain cell shape and rigidity
microfilaments
involved in muscular contraction, osmosis, and cell division
support plasma membrane
cilia
move substances along cell surface
sensory roles
centrioles
form miotic spindle during cell division
unpaired centrioles form cilia and flagella
