Write any 8 differences between C 3 and C 4 plant?

C 3 plant C 4 plant They are common in temperate climates. They are common in tropical climates. They include soybean, cassava plants etc. They include maize, sugarcane, and sorghum plants. Carbon dioxide fixation occurs only once. Carbon dioxide fixation occurs twice. All the steps of dark reaction take place in the mesophyll cells. The initial steps are carried out in the mesophyll cells and the subsequent steps are carried out in the bundle-sheath cells. It is the oldest and the most common type of photosynthesis. It is a recent phenomenon. C 3 photosynthesis produces a three-carbon compound. C 4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. It occurs when stomata are open. It occurs even when stomata are closed. The optimum temperature for this photosynthesis is comparatively lower. The optimum temperature for this photosynthesis is comparatively higher.

TCA cycle that is tricarboxylic acid cycle is the second stage of cellular respiration. It is a three-stage process where breakdown of organic fuel molecules occurs in the living cells to release energy in the form of ATP. This energy is needed to grow, divide and perform several metabolic pathways. Basically it is a series of chemical reactions used by all aerobic organisms. It consists of eight steps that includes a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH 2 .
