Chemistry of Plants
What is ATP used for?
Energy
This area is used for gas exchange on a leaf.
Stoma or Stomata
What is the PRODUCT of the Calvin Cycle?
Glucose
This color of light is used the LEAST by plants.
Green
True or False: Only trees use photosynthesis. Flowers do not.
False.
C6H12O6 is the chemical formula for what?
Glucose
Photosynthesis is carried out in THIS part of a plant.
Chloroplast
The light reaction requires sunlight and THIS to produce oxygen.
water
Light energy is absorbed in THIS GREEN substance, found in the chloroplast.
Chlorophyll
Carbon dioxide gas is used by plants to manufacture complex carbohydrates (glucose) through the process of....
Photosynthesis
This gas is taken into a plant from the atmosphere.
CO2
What causes stomata to open and close?
Osmotic changes.
What is the main source of energy for plants?
Sunlight
True or False: Plants can do photosynthesis WITHOUT sunlight.
False.
This is the name for an organism that can make its own food.
Autotroph
Glucose is made in the leaves. Which direction does it flow through the plant?
down. To feed the rest of the organism.
Why are stoma (stomata) located on the bottom of a leaf?
To help prevent water loss.
Both light and dark reactions occur HERE.
Chloroplast
Does light intensity affect the rate of photosynthesis?
Yes- but only to a point. You still need enough CO2 and Water.
Explain the process of photosynthesis in your own words.
Light from the sun, Water from the ground, and CO2 from the atmosphere are used to make Glucose. Oxygen is released back into the atmosphere.
Give the full equation for photosynthesis.
Sunlight + 6H2O + 6CO2 ---> C6H12O6 + O2
Water flows in which direction through a plant?
Up from the roots.
True or False: The Calvin Cycle requires light.
False
True or False: Light travels in waves.
True
Photosynthesis uses sunlight to convert water and carbon dioxide into THESE products.
Glucose and Oxygen
