Their chlorophyll
Bee pollination
What will happen to the photosynthesis rate if you increase the intensity of light?
Photosynthesis rate will increase.
Photosynthesis rate will decrease.
Photosynthesis rate will remain the same.
Photosynthesis will stop.
How is the leaf adapted to do photosynthesis?
The leaf's upper layer is thin and transparent to allow light to pass through.
The leaf's palisade layer has the most chloroplast to absorb the maximum amount of light possible.
The leaf's lower layer has many stomata to allow gases to diffuse.
All of the descriptions are true.
If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars (rate of photosynthesis)?
Sugar production will likely increase.
Sugars will not be produced.
The rate of sugar production will decrease .
Fewer sugars will be produced at first, but then the plant will recover.
What is the role of stomata?
Transport sugar
Where photosynthesis happens
Openings in the leaf that allows gas in and out the plant
