ribosomes
site of protein synthesis
endoplasmic reticulum
tunneling system for the fast movement of large molecules through the jello

folding of proteins. looks like pancakes.
mitochondria
site of respiration breaks down fulcos
vacuoles
capture and digest food. storage area.
chromoplasts
site of photosynthesis
motility structures
cilia:thousands of tiny hair that vibrate in an organized matter. flagella: single hair that beats for motion
lysome
cells garbage disposal breaks down large molecules into smaller molecules enzymatically
centriole
organizes the dna for mitotc division
diffusion
movemnet of molecules from high to low concentration
diffusion in liquids
molecules are farther apart easily slower than in gases
osmosis
diffusino of water molecules through a semipermeable membrane
dna
deoxyribose nucleic acid
dna is a
polymer
nucleotide is a
monomer

nitrogen bases phosphoric acid group. adenine-thymine guanine-cytosine.
dna paris are joined by?
hydrogen bonds
shape of dna
double helix
how many base pairs per twist?
five
turgid
a cell that is full of water
DNA replication
when a new cell is going to be made each new cell has to have the same amount of DNA.
steps for Dna replication
Dna uncoils
enzymes eat through H bonds
naked unattached nucleotides bond to pose base ends
two ladders complete 2 identical DnA ladders

46 in humans
how does information get from nucleus to ribosomes
messenger Rna
comparing Dna to Rna
Dna is double stranded and found in nucleus. RNA is single stranded and found in cytoplasm. in Rna adensine is paired up with Uracil.
theory
a model that explains current observations and predicts new observations
hypothesis
question that are testable through experiment or observation.
natural selection
the survival and reproduction of organisms that are best suited to their environment.
adaptations
increase the chances that an organism will survive and reproduce in its particular environment.
element
a substance made of only one kind of atom.
compound
elements can combine chemically in many ways.
chemical bonds
are formed by the attraction, sharing, or transfer of outer electrons from one atom to the other.
chemical reaction
involves making or breaking chemical bonds.
activation energy
is the energy needed to get a chemical reactino started
ionic bond
the attraction between oppositely charged ions
covalent bonds
two atoms share one or more pairs of electrons.
