seaweed
yeast
Which is a difference between photosynthesis and cellular respiration?
Photosynthesis can produce glucose without oxygen.
Photosynthesis occurs only in plants, and respiration occurs only in animals.
Cellular respiration stores energy, but photosynthesis releases energy.
Cellular respiration releases oxygen, but photosynthesis releases carbon dioxide.
How would the environment change if there were fewer plants to carry out photosynthesis?
It would have more oxygen.
It would have more glucose.
It would have more ATP energy.
It would have more carbon dioxide.
