35 Cards in this Set

  • Front
  • Back
functions as the gatekeeper of the cell
cell membrane
function includes destroying cells and getting rid of old cell parts
lysosome
storage organelle--holds water, waste, minerals
vacuole
energy producing organelle--generates ATP
mitochondria
plant cell organelle for synthesizing sugars
chloroplast
organelle that is the site of protein synthesis
ribosome
protects a plant cell & gives it structure
cell wall
method of transport that moves particles from a high concentration to a low concentration; is free
diffusion
the movement of water from where there is a lot to where there is a little across a membrane
osmosis
transport of particles from where there are few to where there are already a lot; requires cell energy
active transport
a specific transport mechanism that uses active transport to put sodium ions outside the cell & potassium ions inside the cell
sodium potassium pump
type of transport in particles move through a protein channel from a high to a low concentration
facillitated diffusion
structures made of DNA that reside in the nucleus of the cell
chromosomes
the fluidy portion inside the cell in which the other organelles float
cytoplasm
cylindrical structures that are part of the cytoskeleton; also are involved in moving the organelles around
microtubules
organelle that produces the ribosomes
nucleolus
long skinny structure involved in the cytoskeleton structure;
microfilament
structures made of microtubules that are involved in moving the chromosomes around during cell division
centrioles
an environment for a cell that causes water to be drawn out of the cell
hypertonic
an environment for a cell that causes water to be pushed into the cell
hypotonic
an environment for a cell that causes water to be equal on either side of the membrane
isotonic
the outward force experienced by a cell due to water on the inside
turgor pressure
the process of a cell engulfing a large particle
endocytosis
the process of a cell expelling a large particle
exocytosis
type of membrane that allows certain particles to pass through but not others
selectively permeable
the end result of diffusion; when the number of particles on each side of the membrane is the same
equilibrium
organelle that packages products for the cells and ships them out as vesicles
golgi apparatus
organelle that serves as the transport highway for the cell--moving protein from the ribosomes to the Golgi
endoplasmic reticulum
large organelle in a plant cell that stores water--keeps the plant upright
central vacuole
organelles that function to store starch in plant cells
leucoplasts
vehicles that are packaged at the golgi & are shipped out of the cell
vesicles
control center of the cell; houses the nucleolus
nucleus
plant cell organelle that provides pigments/colors for plants
chromaplast
numerous, short hairlike extensions used for moving the entire cell
cilia
long, threadlike structures outside of the cell used to move the entire cell
flagella
