difference of prokaryotic vs eukaryotic
do both have a cell membrane? true or false
true
a cell must carry on life processes of what
acquiring nutrients, cellular respiration, excretion
if the concentration gradient is higher what will the diffusion rate do
the diffusion rate will go up
how do membranes control the passage of materials into and out of the cell
they are semi permeable
how much of the living cell is made up of water
70-95%
do both have membrane bound organelles true or false
false
what is it called when all molecules are constantly moving
Brownian movement
what is one way the rate of diffusion can be affected (there are three ways)
difference in concentration gradient
what is facilitated difference
large molecules like glucose need help diffusing into the cell
water continues to diffuse back and forth across a membrane from high water concentration to low water concentration. the net movement will stop when what is reached
equalibrium/dinamic equalibrium
do prokaryotic or eukaryotic have many different types of cells
eukaryotic
in which direction does diffusion go
high to low
what is a way the rate of diffusion can be affected (there are three ways)
temperature(the higher the temperature the quicker the rate
what is active transport
moving molecules against the concentration gradient
when the concentration of solutes outside is the same as inside you have a what solution and what kind of cell
isotonic solution and a happy cell
do animal and plant cells both have membrane bound organelles
true
the process of molecules moving higher concentration to lower is called what
diffusion
what is a way the rate of diffusion can be affected (there are three ways)
pressure higher pressure increases the rate of diffusion
what is extra cellular
inside of the cell
when the concentration of solutes outside is lower than inside you have what type of solution and what kind of cell
hypotonic solution and swollen cell
which has a large central H20 vacuole
plant cells
what is the difference in concentration of molecules of a substance from the highest to lowest number is called what
concentration gradient
oxygen and carbon dioxide dissolve into what so they can pass right through the cell membrane
lipids
when the concentration of solutes inside is lower than outside you have what type of solution and what kind of cell
hypertonic and shriveled cell
