Mesophytes - Plants with habitats that are neither too wet nor too dry
Xerophytes - Plants with very dry habitats
Hydrophytes are aquatic plants that may be free floating, fully submerged or partly submerged (amphibious) in water. The vascular tissue of hydrophytes is very poorly developed. Examples of hydrophytes are Ottelia, Sagittaria and Utricularia.
Mesophytes are plants that live in habitats that have a moderate supply of water (neither too wet nor too dry. Mesophytes are usually large, fast growing, and have well developed roots and leaves. Examples of mesophytes are clover and maize (corn).
Xerophytes are plants that are able to thrive with very dry habitats where the available soil water is low. Examples of xerophytes are Acacia and Carthamus.
This pathway for forming ATP needs no oxygen and the ATP that is produced are in very low concentration. The low amount of ATP production occurs when the cell goes for anaerobic respiration in which the cell produces less ATP. This type of ATP production occurs only when the body requires ATP quickly so that's why the body uses this type of respiration during exercise and running activities etc.
