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
|
