50 Cards in this Set

  • Front
  • Back
what is cohesion
when molicules stick together
what is adhesion
when unlike molicules stick together
what is surface tension
it allows some animals to walk on water
how does water go to the top of a tree
each drop pulls the one behind it up
why does ice float
it is less dense then the water
why is it important that ice is less dense then water
so then it wont kill all the organisms from when it floats up
what is a solvent
liquid that dissolves substances
what is a solute
the substance that gets dissolved
what is an acid
anyhting that dissochates in H+ ions
what is a base
anything that dissochates in OH ions
how does a buffer work
it absorbs H+ ions if there are to many released
what does an organic compound contain
contains carbon
what does an inorganic compound not have in it
has no carbon in it
what do these materials contain, monosaccharide, disaccharide, and a polysaccharide
what are the building blocks of fats
why is cellulose considered roughage fiber for humans
humans dont have cellulose
what is the function of a carbohydrate
to give off proteins
what is a phosphillipid bilayer
two fatty acids chained
what is a trigliceride
three fatty acid chains
what are the building blocks of proteins
amino acids
what is dehydration synthesis
when your body loses water
what is hydrolysis
when water seperates molicules appart
what does a eukaryotic cell have
what doesnt a prokaryetic cell have
what do all cells have in common
cell membrane, dna, cytoplasm, ribosomes, and endoplasmic reticulium
what are the differences between plant and animal cells
cell wall, plastids, vacuoles, shape, centrioles, and lysosomes
why do cells need to be bathed by fluids on both sides
to transport molicules in and out of the cell
how do plants stand up without a skeleton
the pressure of the water
what causes leaves to change colors
what is passive transport
a transport that dosnt have any energy
what is diffussion, and what direction does it move
where molicules spread themselves out in space, and from high to low concentration
what is equillibrium
it is the distribution of molicules
what is facilitated diffusion
where proteins move molicules in and out of the cell
what is osmosis
movement of molicules from high to low concentration
what is a hypertonic solution
it is when the cells get to much water
what happens to a cell when it is put in a hypertonic solution
it will swell up
what is a isotonic solution
where a cell dosnt get enuf water
what happens to a cell when it is put in a isotonic solution
it will shrink
what is active transport
it is energy used to move molicules from LOW TO HIGH concentration
what is ment by moving up a concentration gradient
going low to high concentration
where does all life come from
the sun
what can an autotroph producer do
make their own food
what cant a heterotroph producer do
make their own food
what is kenetic energy
what is happening now
what is potential energy
energy being stored before it is used
is glucose the only molicule formed during photosynthesis
no carbon dioxide is too
how do chlorophyll atoms trap the suns energy
it uses chloroplast to trap it
what part of the plant does photosynthesis occur
in the higher energy level parts
what organelle part of the plant does photosynthsis occur
in the heterotrophs
what is the purpose of photosynthesis
to recycle crutial chemicals in the enviroment
