Uncrowded
Spacious
When particles move from areas of high concentration to areas less concentrated, this has taken place.
diffusion
mitosis
endocytosis
photosynthesis
What process occurs when WATER diffuses across a membrane?
endocytosis
mitosis
osmosis
nuclear fission
Which diagram best shows the end result of diffusion?
F
G
H
J
Why is diffusion and osmosis important to cells?
It allows them to take in materials without using energy.
It allows them to reproduce.
It allows them to absorb sunlight.
It allows cells to use all energy.
The picture is an example of _________________.
isotonic
diffusion
osmosis
active transport
When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.
osmosis
equilibrium
diffusion
hypertonic
In this given scenario, corn syrup is hypertonic to an egg with a dissolved shell. What will happen to the egg when it is place in corn syrup?
It will stay the same.
It will swell- get bigger.
It will shrink- get smaller.
In the given scenario what will happen? An egg with a dissolved shell is placed in pure water for 48 hours.
Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
The egg will gain water and swell.
The egg will lose water and shrink.
What does selectively-permeable mean?
The cell controls what passes in and out of the cell
Nothing gets through
The cell lets only large substances through
Which way will the water molecules move during osmosis?
Out of the cell, so the cell shrinks.
Out of the cell, so the cell swells.
Into the cell, so the cell shrinks.
Into the cell, so the cell swells.
What is diffusion?
when molecules move
when molecules move from a high concentration to a low.
no movement
molecules move everywhere
Where is there a low concentration of dye?
at the bottom of cup
in the color
at the top of cup
no concenteraion gradient
The picture below is an example of _________________.
osmosis
isotonic
diffusion
active transport
Osmosis is the movement of _____ across a membrane.
food
energy
oxygen
water
During osmosis
water moves from high to low concentration
large or oddly shaped molecules move across a cell membrane
water moves when energy is used
proteins are built
Permeable means
things can pass through
the concentration levels are different
it is permanent
things are stuck
What a cell needs to transport particles by active transport?
Sun
Wind
Energy
Channels
If there is 5 percent water inside a cell and 5 percent water outside a cell
more water will move inside the cell
more water will move outside the cell
There will be no movement of water cells
The movement of molecules against a concentration gradient
simple diffusion
facilitated diffusion
active transport
osmosis
The picture is an example of...
active tranport
passive transport
diffusion
osmosis

big
small
crunchy
water
