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 humans breathe in? What do humans breathe out?
In Oxygen, out Carbon Dioxide
100

An example of phototropism

plant bending toward light source

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 do plants breathe in? Breathe out?
In Carbon Dioxide, Out Oxygen
200
An example of gravitropism

Stems grow up, roots grow down

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
Where does gas exchange take place in plant
Leaves
300

An example of thigmotropism

Vines growing up a fence

400
In Diffusion particles move from a low concentration to a high concentration. True or False?
False
400
In the leaves what cells allow water to evaporate
stomata cells
400
What is the formula for Photosynthesis
Carbon dioxide + Water + sun = glucose and oxygen
400
Why do plants need to breathe in Carbon Dioxide
It is needed for photosynthesis
400

what hormones are responsible for cell division

gibberllins and cytokinins

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

What is the formula for cellular respiration?

glucose + oxygen -> carbon dioxide + water + ATP

500

what plant hormone helps fruits ripen?

ethylene
