Plant
What is matter?
Anything that has mass or volume - Made from atoms
What is the main purpose of photosynthesis?
To help create food molecules by giving the plant energy.
What parts of the plant are involved in the shoot system?
Stem, leaves, flowers, buds, fruits/veggies
What are the inputs necessary for photosynthesis?
Light, CO2, H2O.
What are the outputs created by photosynthesis?
Oxygen, water vapor
What is a food chain?
The order that matter transfers from one organism to another.
When do plants not do photosynthesis?
When it's dark.
When there are no leaves.
what is a stomata?
Small openings on the plant that open and close to let matter in and out.
What is the main form of matter that enters the plants root system?
Water (H2O)
True or False:
Roots systems are the main absorbers of carbon dioxide on a plant.
False!
Is matter created, destroyed, are transformed during photosynthesis?
Transformed!
What happens to carbon atoms during photosynthesis?
They combine with hydrogen from water to create glucose molecules.
Where on the plant are the most stomata found?
The underside of the leaf.
What gas is absorbed through the shoot system during photosynthesis?
Carbon Dioxide!
During the day time, what do the stomata release?
Oxygen & water vapor.
What is cellular respiration?
When cells turn food molecules (glucose) into energy for the plant.
why do plants need both photosynthesis and respiration?
They both provide energy for the plant (Light vs no light)
How is energy stored inside the plant.
It is stored as starch inside the roots.
During cellular respiration, what molecule goes into the plant?
Oxygen.
During cellular respiration, what two substances are released into the atmosphere?
Carbon Dioxide & Water Vapor
Why is carbon cycling important for life on earth?
Plants need carbon to make food molecules --- Plants release oxygen.
Animals eat food molecules (food chains) --- animals release carbon dioxide
Both need the other.
During photosynthesis, light energy is converted into this type of stored energy?
Glucose!
How do plants use energy during the day vs at night?
During the day plants are making food molecules. At night plants use the food molecules as energy to survive, not making any new molecules.
BLANK atoms and BLANK atoms come together to form food molecules inside the plant.
Carbon dioxide and water.
Can plants move to photosynthesis better?
Yes! They move towards light sources.
