cell structure/function Flashcards
final review
Ribosomes
make proteins
located in cytoplasm/RER
made in nucleolus
nucleus
double-membraned storage for DNA
plasma memrane
semi-permeable membrane that protects cell
what is the plasma membrane made of?
phospholipid bilayer
phospholipid parts
head- hydrophilic
tail- hydrophobic
hydrocarbon
main energy source of the world
cell wall
ONLY IN PLANTS; protects/mantains cell shape
what is cell wall made of?
cellulose
RER
packages products into vesicles and dispatches them
produces protein
SER
makes lipids; detoxifies drugs
Examples of lipids
steroids, phospholipids
Golgi apparatus
modifies, packages, and distributes products (many do exocytosis)
lysosomes
sacs with digestive enzymes that fuses with harmful objects to break it down
vacuole
storage of materials
central vacuole
only in plants
pumps out excess water, store nutrients, helps growth, contains pigments/poisons
