photosynthesis
Without autotrophs and ______________life as we know it on earth would not exist...
water, carbon dioxide
What materials do plants use from the ground and air to make food?
sunlight
What energy source is needed for the plants to make food?
glucose
What is the food that plants make?
chlorophyll
What is a chemical that helps photosynthesis in plants?
chlorophyll disappears
Why do you begin to see yellow and green colors in leaves during the fall?
glucose is trapped in leaves after photosynthesis stops.
Why do you see reds and purple leaves in the fall?
xylem, phloem
What makes up vascular tissues of the plant?
In the fall, glucose and waste products are trapped in the leaf and there is no fresh water to renew it.
Why does chlorophyll begin to disappear in the fall?
photosynthesis equation
light dependent, light independent reaction
