Activity 10.2 How Do C 3 , C 4 , and CAM Photosynthesis Compare?

08/04/2010 · Best Answer: The three types of photosynthesis are C3, C4, and CAM

How would you compare and contrast C3, C4, and CAM ..

Compare & Contrast
C3- No separation of initial CO2 fixation and calvin cycle
-Stomata opens in the day
-Best adapted to cool, wet environments
-mesophyll cells perform complete photosynthesis in C3 plants

C4- Separation between mesophyll and bundle-sheath cells (in space)
-Stomata opens in the day
-Best adapted to Hot, sunny environments.

C3, C4 and CAM Essay Question | Stoma | Photosynthesis

C3: Rice, soybean, wheat, rye, oats,
millet, barley, potato
C4: Maize (corn), sorghum, pearl millet
and sugarcane
CAM: Pineapple, Cactus
The C4 plant will have the highest rate of photosynthesis over 12 hours of daylight compared to CAM and C3 plants because C4 plants can thrive in direct sunlight and it uses Pep carboxylase instead of Rubisco.
Experimental Design
There will be one plant of each kind; a soybean plant is a C3 plant, a sugarcane plant is a C4 plant, and a cactus is a Cam plant.
There will be 3 chambers with intense sunlight(50 watts)
shining into all of the chambers equally.

Nevertheless, in over 2 billion years, neither nature nor human genetic engineering has been able to eliminate or even significantly reduce the oxygenase activity of Rubisco without also affecting the carboxylase activity.C4 plants have evolved a mechanism to deliver CO2 to Rubisco In order for plants to take in CO2, they have to open structures called stomata on their leaves, which are pores that allow gas exchange. Plants also lose water vapor through their stomata, which means that they can become dehydrated in dry conditions as they photosynthesize. Because photorespiration (reaction of rubisco with oxygen instead of carbon dioxide) drastically reduces the efficiency of rubisco, which is already a very slow-working enzyme, this means plants in dry conditions are at risk of death by dehydration even as they’re trying to make their own sugar from photosynthesis to stay alive.Many plants which live in dry conditions have evolved an alternative carbon fixation pathway to enhance the efficiency of rubisco so that they don’t have to keep their stomata open as much, and thus they run less risk of dying due to dehydration. These plants are called C4 plants, because the first product of carbon fixation is a 4-carbon compound (instead of a 3-carbon compound as in C3 or “normal” plants).
