C3 plants fix the carbon dioxide with the help of Rubisco through a process called photorespiration. C 4 plants are usually identified by their higher 13 C 12 C isotopic ratio compared to C 3 plants or their typical leaf anatomy.

They carry out a dark reaction.
C3 vs c4 plants. Examples of C4 plants include corn sorghum sugarcane millet and switchgrass. Furthermore they have chloroplasts to carry out photosynthesis. Both C3 and C4 plants.
C4 plants examples are corn sorghum sugarcane millet and Panicum virgatum switchgrass. Both C3 and C4 plants fix carbon dioxide and produce carbohydrates. What are the Similarities Between C3 and C4 Plants.
Corn and sorghum are C4 plants which is why heat units are important to these crops. C3 plants are said as cool season plants while C4 plants are said as warm season plants. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
While most are graminoids other growth forms such as forbs vines shrubs and even some trees and aquatic plants are also known among C 4 plants. C4 plants About 85 of total plants species are C3 and only 15 are C4 plants. Everything being equal if you raise the CO2 levels the C3 plants will theoretically benefit from increased CO2 more than C4 plants Most of the crops grown on the Prairies including wheat barley canola flax and soybeans are C3 plants.
C3 Plant and C4 Plants both are productive but C4 plants are more productive and efficient. C3 plants vs. Both C3 and C4 plants require 6 molecules of CO2 and 12 molecules of water to synthesis one molecule of glucose.
Examples of C4 plants include corn sorghum sugarcane millet and switchgrass. As a result in high light and temperature environments C4 plants tend to be more productive than C3 plants. Therefore the efficiency of photosynthesis in C4 plants is higher than its efficiency in C3 plants.
O2 can bind to Rubisco instead of CO2. Surrounding the leaves are mesophyll cells that contain a much more active enzyme called phosphoenolpyruvate PEP carboxylase. C3 grasses release 833 molecules of water per co2 molecule while C4 grasses release 277 molecules of water.
The carbohydrate product of both C3 and C4 cycle is a three-carbon sugar phosphate molecule known as Glyceraldehyde 3 phosphate G3P. Also both types of plants carry out the same light reaction. The main difference between C3 C4 and CAM photosynthesis is that C3 photosynthesis produces a three-carbon compound via the Calvin cycle and C4 photosynthesis produces an intermediate four-carbon compound which split into a three-carbon compound for the Calvin cycle whereas CAM photosynthesis gathers sunlight during the day and fix carbon dioxide at night.
C3 plants are photosynthetic plants whereas C4 are tropical plants. C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. C4 have higher water efficiency than C3 plants.
The main difference between C3 and C4 plants is that single fixation of carbon dioxide is observed in C3 plants and double fixation of carbon dioxide is observed in C4 plants. However the C4 anatomical and biochemical adaptations require additional plant energy and resources than C3 photosynthesis and so in cooler environments C3 plants are. C4 photosynthesis is a biochemical modification of the C3 photosynthesis process in which the C3 style cycle only occurs in the interior cells within the leaf.
