- Front
- Back
Forms the boundary of the cell; acts as a selective barrier allowing certain materials to pass but not others
|
Cell Membrane
|
|
the entire region between the nucleus and the cell membrane; consists of cytosol
|
cytoplasm
|
|
contains most of the genes that control the eukaryotic cell; generally the most conspiciou organelle in a eukarytoc cell
|
nucleus
|
|
contains the nucleolus and chromatin
|
nucleus
|
|
where the components of the ribosomes are synthesized and assembled; found in the nucleus
|
nucleolus
|
|
consists of DNA and protein; condense to form chromosomes
|
chromatin
|
|
double membrane that forms the boundary between the nuclear contents and the cytoplasm; perforated with pores
|
nuclear envelope
|
|
site of protein synthesis; suspended in the cytosol; produces poretins for use within the cell
|
free ribosomes
|
|
site of protein synthesis; attached to the outside surgace of the endoplasmic reticulum; produces proteins for use outside the cell or for use in the cell membrane
|
bound ribosomes
|
|
synthesisz lipids including phospholipids and steriods
|
smooth er
|
|
metabolizes carbs;detoxifies drugs and poisons; stores calcuim ions, lacks attached ribosomes
|
smooth er
|
|
consists of flattened membranous sacs; receives transport vesicles from the ER
|
golgi apparatus
|
|
modifies ER products; produces certain molecules;produces lysosomes and secretaory vesicles
|
golgi apparatus
|
|
channels proteins to transport vesicles; attaches carbs to some proteins
|
rough er
|
|
involved in membrane production through the production of vesicles; has attached ribosomes
|
rough er
|
|
carries er products to the golgi
|
transport vesicle
|
|
carries golgi modified products to the cell membrane; fuses with the cell membrane releasing the contents to outside the cell
|
secretory vesicle
|
|
membrane found sac of hydrolytic enzymes; enzymes are used to digest food, other molecules, and old worn out cell parts
|
lysosomes
|
|
membrane bound sacs; larger than vesicles; stores materials
|
vacuoles
|
|
site of cellular respiration; produces ATP from sugars, fats, and other fuels
|
mitochondria
|
|
site of photosynthesis; produces food using light energy, CO2 and H2O
|
chloroplasts
|
|
contains enzymes that transfer H from substrates to oxygen producing H202; detoxifies alcohol
|
peroxisomes
|
|
paired structures found in animal cells; consist of microtubules in a 9+0 arrangement; involved in cell division
|
centrioles
|
