Cards

Term


Cell Wall
Definition
strong, stiff, made of cellulose, plant cells only, protect/support plant
Term



Cell Membrane
Definition
doorway of cell, support, protection, controls movement of materials in and out of plant and animal cells
Term
Plant: right inside cell wall Animal: outer covering of cell
Definition



Cell Membrane
Term



Nucleus
Definition
control center, controls what goes on in cell, DNA stays here to run things,large, oval shape, both plant and animal cells
Term



Nuclear Membrane
Definition
surrounds nucleus, support/protect nucleus, allow materials to come and go from nucleus
Term



Chromatin/chromosomes
Definition
directs all activities in cell like growth and reproduction, passes traits of cells to new cells, made up of DNA and RNA
Term



Nucleolus
Definition
makes ribosomes, small,circular object found inside the nucleus
Term



Cytoplasm
Definition
gel-like fluid always moving in cell, area between nucleus and cell membrane, includes all organelles except nucleus and those inside it
Term



Mitochondria
Definition
make most of the energy in animals cell, rod-shaped objects, breaks food down into energy
Term



Endoplasmic Reticulum
Definition
transportation system, clear, tubular passageways, transportation system for entire cell
Term



Ribosome
Definition
protein factory, most stuck to surface of endoplasmic reticulum while some float in cytoplasm, small, red, grain-like objects
Term



Golgi Bodies
Definition
Mailroom, take proteins and things from endoplasmic reticulum to pack and send to all parts of cell, sends material outside of cell
Term



Chloroplast
Definition
energy producer, plant cell only, large, irregular shaped green object that surrounds the vacuole, has green chlorophyll
Term



Vacuole
Definition
storage tank, ONE large, round, water-filled sac in plant cell, few small vacuoles in animal cell
Term



Lysosome
Definition
cleanup crew, only animal cell, small, round object, help in digestion for cell,
Term



Prokaryote cells: do they have a nucleus? Where is genetic information?
Definition
No nucleus, like bacteria cell, genetic information floats around in cytoplasm
Term



Eukaryote cells: Do they have a nucleus? Where is genetic material?
Definition
yes, have nucleus, which protects and supports genetic material
Term
gel-like fluid always moving around in the cell
Definition



Cytoplasm
Term
cell walls: only in which kind of cell?
Definition
Plant cells only
Term
Control center, "brain" of cell
Definition



Nucleus
Term
surrounds, supports, protect nucleos
Definition



nuclear membrane
Term
makes ribosomes
Definition



nucleolus
Term
area between nucleus and cell membrane
Definition



cytoplasm
Term
passes traits of cells to new cells
Definition




chromatin/chromosomes
Term

DNA stays here to run things

 

Definition



nucleus
Term
one large, round, water-filled sac in the plant cell, or a few small ones in the animal cell
Definition



vacuole
Term
Only in animal cell, aids in digestion
Definition



lysosome
Term
sends materials outside of the cell
Definition



Golgi bodies
Term
made in nucleolus, made of RNA, and makes protein for cell
Definition



ribosome
Term
directs all activities in the cell like growth and reporduction
Definition



chromatin/chromosomes
Term
digests old and worn out cell parts so new ones can be made
Definition



lysosome
Term
has green chlorophyll which takes sun's energy and makes food
Definition



chloroplast
Term
breaks food down for energy, rod-shaped
Definition



mitochondria
Term
clear tubular passageways
Definition



endoplasmic reticulum
Term
where photosynthesis takes place
Definition



chloroplast
Term
two structures only in plant cells
Definition
cell wall and chloroplast
Term
structure only in animal cells
Definition



lysosome
