ch6 The Cell Flashcards
cytosol
the fluid portion of a cell’s cytoplasm
cytoplasm
all of the cytosol and organelles within a cell
nucleoid
non membrane enclosed area of DNA for a prokaryotic cell.
all cell membranes within and without are usually…
lipids and proteins
ribosomes
complexes that make proteins
chromatin
material consisting of DNA and proteins visible as actual chromosomes
endoplasmic reticulum
synthesizes membrane and proteins
mitochondria
cell respiration occurs and ATP is made
chromosomes
discreet units of DNA
difference between smooth and rough ER
smooth ER lacks ribosomes
glycoproteins
proteins with carbohydrates covalently bonded to them
Golgi apparatus
manufacturing, warehousing, sorting, and shipping
cis face
receiving end of golgi
trans face
shipping end of golgi
lysosomes
digestive organelles
peroxisome
transfers hydrogen from a substance to oxygen to make hydrogen peroxide
cristae
inner folds of mitochondria
plastids
plant organelles that manufacture or store compounds for the plant
centrosome
microtubule organizing center
centrioles
2 organelles in a centrosome: 9 sets of 3 microtubules
dynein
large motor proteins which cause some organelles to bend or cilia to wave
actin
a globular protein
myosin
microfilament-based motor protein
middle lamella
thin layer of sticky polysacchradides in between plant cells
collagen
an abundant protein which forms strong fibers outside of cells
integrins
surface receptor proteins that connect the extracellular with the intracellular
