Describe two alternative photosynthesis pathways found in plants suggest how how these adaptions might plants

a. Sugar cane, corn, carbgrass which are identified as C4 Plants allow fixation of carbon dioxide into four carbon compounds. This happens during the  hottest time of the day - their so-called stomata gets partially closed. C4 plants have been identified to lose only half of the water that C3 plants lose when they produce the similar amount of carbs.

b.CAM PATHWAY - Plants such as pineapples and cactus have different approach to adapting heat. Carbon is fixed through a cam pathway. They use it to open their stomata at night and close it in the morning.
