Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 99-99.5% is lost by transpiration. Leaf surfaces are dotted with pores called stomata, and in most plants they are more numerous on the undersides of the foliage.
Best Answer: Anaerobic respiration occurs in muscle cells when they do not have access to enough oxygen to complete aerobic respiration to generate all the ATP they need. In human muscle cells, the end product is lactate/lactic acid. Anaerobic respiration occurs when cells do not have enough Oxygen to undergo the process of aerobic respiration. In animal cells (like humans) anaerobic respiration happens mostly on muscle cells through a process called Fermentation that happens outside the Mitochondria.
