What is the definition of Diffusion
the movement of particles from high concentration to low concentration
100
Define Osmosis
The movement of water particles from an area of high solute concentration to an area of low solute concentration
100
What is photosynthesis used for
plants making their own food
100
What do plants use transpiration to do
Move water up the stem to the leaves
100
What do humans breathe in? What do humans breathe out?
In Oxygen, out Carbon Dioxide
200
What diffuses into the plant roots
Nutrients and Minerals
200
Where does osmosis take place
In the roots
200
where does photosynthesis take place
in the leaves
200
What is the driving force for transpiration
water evaporating out of the leaves
200
What do plants breathe in? Breathe out?
In Carbon Dioxide, Out Oxygen
300
What Diffuses into the plant leaves
Carbon Dioxide
300
What direction does osmosis move particles
high to low
300
what special cells in the leaves store sun energy and make the leaves green
chloroplasts
300
In the leaves what cells allow water to evaporate
stomata cells
300
Where does gas exchange take place in plant
Leaves
400
In Diffusion particles move from a low concentration to a high concentration. True or False?
False
400
What is a semipermeable membrane
it is like a gate that will only allow water particles to cross through
400
What is the formula for Photosynthesis
Carbon dioxide + Water + sun = glucose and oxygen
400
What is evaporation
water changing from liquid state to gas state
400
Why do plants need to breathe in Carbon Dioxide
It is needed for photosynthesis
500
What would happen if plant could not use diffusion
no way to move around nutrients and minerals. no way to get carbon dioxide
500
How is osmosis different then diffusion
it is specifically about the movement of water particles
500
what would happen to a plant that was locked in a dark room and why
it would die because it would not be able to create food for itself because it would have no sun energy to trigger photosynthesis
500
If a plant is in the sun will the stomata be open or closed
they will be open
500
What special cells in the leaves open and close for gas exchange to take place
stomata cells
