C4 and CAM ESSAY A. C4 and CAM plants are plants that use certain special compounds to gather carbon dioxide (CO 2 ) during photosynthesis. Using these compounds allows these plants to extract more CO 2 from a given amount of air‚ helping them prevent water loss in dry climates. CAM and C4 plants are similar with the exception that CAM only opens up the stomata’s at night. They both photosynthesis at the same rate for the majority at a time and are tolerate to heat. Plus C4

The C4 & CAM Pathway Many plant species that evolved in hot‚ dry climates fix carbon through alternative pathways. Under hot and dry conditions‚ plants can rapidly lose water to the air through small pores called stomata. Stomata (singular‚ stoma)‚ are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata

The location of the two systems in C4 plants is in the bundle sheath cells. The mesophyll cells that surround the bundle sheath cells do not contain Rubisco. They fix carbon dioxide by combing a 3 carbon molecule‚ which results in a 4 carbon acid and is transported to bundle sheath cells. The carbon molecule that

The factors affecting plant yield: light level Abstract The factors affecting Zea mays‚ maize (C4) and Pisum sativa‚ or pea (C3) plant yield and growth patterns placed under shade and full sunlight were investigated. 20 plantlets placed into four vermiculite compost pots (5 from each plantlet) and submitted to fertilizer or no fertilizer. And after 4 weeks the results showed that maize grown in light with no fertilizer had a higher relative growth rate and root to shoot ratio indicating the allocation

Sugarcane is one of the world’s major food-producing C4 crops‚ providing about 75 % of sugar produced in the world for human consumption (Souza et al. 2008). World sugarcane production is close to 1.9 billion tonnes per annum and is concentrated in tropical regions‚ particularly developing nations in Latin America‚ Africa and Asia. India is the second largest producer of sugar after Brazil with a global share of 17% in 2014-15. Over five million farmers are involved in the cultivation of sugarcane

termed nitrogen fixation; these bacteria are either free-living or form symbiotic associations with plants or other organisms (e.g. termites‚ protozoa) other bacteria bring about transformations of ammonia to nitrate‚ and of nitrate to N2 or other nitrogen gases many bacteria and fungi degrade organic matter‚ releasing fixed nitrogen for reuse by other organisms. All these processes contribute to the nitrogen cycle. We shall deal first with the process of nitrogen fixation and the nitrogen-fixing

Evergreen Do we as humans only live to die? One can’t understand the life of another‚ unless he/she has experienced that life first hand. People don’t realize that we (humans) are all playing the same role in life. William Shakespeare brilliantly clarifies the true meaning of life through his poem “All the worlds a stage.” Truth of life‚ destiny‚ and human ambition can be seen more clearly through theater than from life itself. The most elaborate themes from the poem are: the fact of all people
