24 Cards in this Set

  • Front
  • Back
phospholipid bilayer
this is a double layer membrane
plasma and cell membrane is made of phospholipid
these phospholipid have a polor hydrophilic "water loving" head
these have a nonpolar "water fearing" hydrophobic two tails
the phospolipids line up and point their heads toward the water and tails inward
chromosome
structures in the nucleus made of DNA and protein
nuclear envelope
the membrane which surrounds the nucleus
nucleolus
the site where the DNA is concentrated when it is the process of making ribosomal RNA
ribosome
organelles made of protein and RNA that direcdt protein synthesis in the cytoplasm
mitichondria
tiny organelles that transfer energy from organic molecules to adenosisne triphophate ATP
ATO powers most of the cell's chemical reactions
endoplasmic reticulum
ER
system of membaneous tubes and sacs called cisternae
functions as an intracellular highway
two types rougha nd smooth
golgi apparatus
flattened membraneous sacs
the sacs nearest the nucleus receive vesicles from the ER
these vesicles contain newly made proteins or lipids
stacked membranes modify the or get adddress labels
they direct them to various parts of the cell
lysosome
vesicles that bud from the golgi body and contain digestive enzymes
cytoskeleton
network of thin tubes and filaments
microtubule
hollow tubes made of a protein called tubulin
tubes radiate out from the centrosome
microtubes hold organelles in place
microfilament
finer than tubules
long threads of beadlike protein actin and are linked end to end
contribute to cell movement of white bvlood cells adn the contraction of muscles
cilium
cilia and flagella are hair like structures that ezxtend from teh surfade of the cell
they assist in movement
flagellum
cilia and flagella are hair like structures that ezxtend from teh surfade of the cell
they assist in movement
centriole
two short cylinders of microtubules at right angles to eacdh other and are situated in the cytoplasm nea the nuclear envelope
cell wall
rigid layer outside the cell's plasma membrane
plant cell walls contain cellulose
cellulose
embedded in a matrix of proteins and other carbohydrates to form a stiff box around each cell
pores in the cell wall allow water ions to enter and exit the cell
central vacuole
large fluid filled organelle that stores water, enzymes metavolic wastes and other materials
plastids
organelles like mitochondra surrounded by double memvrane and containtheir own DNA
chloroplasts, chromoplasts leucoplasts
chloroplasts
use light energy to make carbohydrates from carbon dioxide and water
thylakoids
flattened membraneous sacs
chlorophyll
the main molecule that avsorvs lifht and captures light energy for the cell
chromoplasts
plastids that contain colorful pigments that may or may not take part in photosynthesis
endosymbiosis
chloroplasts and mitochondria are descendant of ancient prokaryotic cells and were incorprated into plant cells
