Detailed explanation-1: -A C4 plant is a plant that cycles carbon dioxide into four-carbon sugar compounds to enter into the Calvin cycle. These plants are very efficient in hot, dry climates and make a lot of energy. Many foods we eat are C4 plants, like corn, pineapple, and sugar cane. So, the correct answer is ‘Sugarcane’
Detailed explanation-2: -C4 Photosynthesis In C4 plants, CO2 is fixed initially into the 4-carbon acids (C4) from the mesophyll and transfers them into the bundle sheath cells, where Rubisco and the enzymes of the Calvin-Benson cycle are localized (Fig. 5).
Detailed explanation-3: -In the C4 pathway, initial carbon fixation takes place in mesophyll cells and the Calvin cycle takes place in bundle-sheath cells. PEP carboxylase attaches an incoming carbon dioxide molecul to the three-carbon molecule PEP, producing oxaloacetate (a four-carbon molecule).
Detailed explanation-4: -Composition C4 is a plastic explosive substance used in military combat units for demolition. The active component of composition C4 is hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine, also known as RDX (Royal Demolition Explosive).
Detailed explanation-5: -Examples of C4 plants include corn, sorghum, sugarcane, millet, and switchgrass. However, the C4 anatomical and biochemical adaptations require additional plant energy and resources than C3 photosynthesis, and so in cooler environments, C3 plants are typically more photosynthetically efficient and productive.
