STUDY
PLAY
eukaryotic cell
"true kernel"; complex; has nucleus and organelles
prokaryotic cell
"before kernel"; simple; no nucleus or organelles; ex. bacteria
nucleoid
prokaryotic region where DNA exists
plasma membrane
most important cell component; selectively permeable; phospholipid bilayer
chromosomes
46 are contained in nuclei; long molecules of DNA wrapped around histone proteins
chromatin
unwound DNA during interphase
endomembrane system
comprised of nuclear envelope, endoplasmic reticulum, golgi apparatus, lysosomes, vacuoles, vesicles, and the cell membrane
smooth ER
endoplasmic reticulum with no ribosomes
rough ER
endoplasmic reticulum with ribosomes dotting the surface
transport vesicles
move molecules between locations inside the cell
golgi apparatus
package materials for "shipping"
endocytosis
using vesicles to bring things in to the cell
exocytosis
using vesicles to export things from the cell
vacuoles
digest food particles to use energy in the cell; central compartment in plant cell is used for osmoregulation
mitochondria
ATP is produced here; 2nd part of cell respiration takes place here; "power house" of the cell
chloroplasts
in plant cells where photosynthesis takes place
thylakoids
flat, membranous discs where light reactions take place in chloroplasts; contain chlorophyll
grana
stacks of thylakoids
stroma
dense inner fluid of chloroplasts
cell wall
only in plant cells; protects the cell
