Photosynthesis has been the focus of much attention than any other physiological process in flora physiology. Photosynthesis is a complex plant metabolic process, similar to respiration and fermentation, in which a plant can synthesize organic matter using light and chlorophyll. According to Kirk 1994: Photosynthesis is a complex physic-chemical process that is the central route in the global carbon cycle serving as single prevalent flux of organic carbon in the biosphere. More so, it specifically involves the assimilation of carbons to be used in this organic matter synthesis, a process called carbon assimilation. …show more content…
Photosynthesis is also the primary source of all the carbon and calories stored in living tissue. It should be noted however, that even though there is a vast supply of carbon dioxide in the atmosphere, tis does not necessarily lead to a cleaner environment as plants will not produce more oxygen. This is simply because there will also be a higher demand, by the plants, for other natural resources including water. Thus the delicate balance between the oxygen produced by plants and the cleanliness of the atmosphere are inter-related. It would therefore be a safe conclusion to say that if plants were to become extinct the human race will soon follow as we would quickly consume the little remaining oxygen in the atmosphere. The fact that photosynthesis is paramount to the survival of the Earth is at this stage unquestionable. If the use of carbon dioxide and the production of oxygen should abruptly stop, that delicate balance referred to earlier will fall apart and the human race will wonder to …show more content…
The phloem consists of living cells arranged end to end. Unlike xylem, phloem vessels contain cytoplasm, and this goes through holes from one cell to the next. Phloem transports sucrose and amino acids up and down the plant. This is called translocation. In general, this happens between where these substances are made and where they are used or stored. It is also interesting to note that plants have pores, called stomata, on the underside of the leaves from which oxygen and water vapor moves out into the ambient atmosphere and carbon dioxide moves in, in a process called transpiration. Once the carbon dioxide moves into the leaf, it diffuses into the plant cells and is taken to the chloroplasts by active transport, where in photosynthesis, it is combined with water to form glucose. Therefore it can be said that plants do not necessarily need a transportation process to move and store glucose and oxygen since these pores account for this
