Question

Why do plants absorb large amountof water tgen rekease out by traspiratiion whut?

Answer 1

Thanks for the question!

It is definitely a very interesting question to solve and do some brainstorming.

Generally, transpiration is a state where the excess of water is lost in the form of water vapor or vapor state (gas) from the aerial parts of plants. The process of transpiration is done to remove large amounts of water which are not required by the individual tissue cells, as, it largely assists synthesis of plants and in particular photosynthesis. The medium of transpiration is similar to that of perspiration which is the escape of water or wastes through salts, minerals, oils, water etc. is transferred to sweat pore which is transferred to the epidermal layer of skin for evaporation giving a cooling effect to the skin and to avoid excessive heat formations around the vital organs and to regulate the total temperature.

Just exactly, the same process is undergone in plants, the stomatal opening or pores are the ones to release water vapors from there it gets accumulated to the layer of cuticle, hence, cuticicular transpiration, lenticular transpiration and stomatal transpiration, all are initiated with the medium of pores to let the vapors escape and the water is released onto the cuticle and lenticular layers and mostly through stomatal openings, water is travelling to the surface of plant making the allowance of entrance for Carbon dioxide to come into the pores and stomata and expelling oxygen in the process, so, transpiration is useful for humans.

Absorption of water throughout the roots are done to extract nutrients form the soil in the solution and wide presence of water molecules which help the translocation and transportation of water and mineral nutrients in the while plant, giving every tissue a adequate requirement of completing the nutritional balances, to avoid deficiencies of plants. In plants too the regulation of water and temperature comes into the act. In some highly modified xerophytic desert plants such as cactus or cacti, the transpiration is greatly reduced by adaptations of thick waxy cuticle layer, more water absorptive retentions through various tissues, spiny leaflets to reduce the angles and lower transpiration, etc. Since, the water is not required and is in excess it is lost through transpiration and the water is absorbed to keep the functioning and the turgidity of the tissues alive and synthesise many reactions (water is the major molecular unit for every reactionary process ever taking place in plants). This also gives a cooling effect on the surface of the leaves (same as humans) and to sustain internal functions and maintaining the climatic environmental conditions (under severe drought conditions the process in in versed or less).
