Ecological niche
Mesophytes plants are found in environments when there is rarely a shortage of raw materials such as water and sunlight meaning the plant has adapted successfully to obtain the energy that the it requires to live and grow successfully. Mesophyte plants have adapted in order to carry out cellular processes that allow them to obtain energy. The mesophyte plant is to carry out photosynthesis by using the two raw materials carbon dioxide and water to form glucose and oxygen using energy from the sunlight. This glucose an then be used to carry out respiration where the plant uses the glucose that its made in respiration and oxygen to form ATP (energy) this is then used by the plant to carry out its life processes in order to survive. The ability to maintain a correct amount of water to carry out these processes is important on the survival of these plants. Mesophyte plants have adapted in order to carry out cellular processes such as photosynthesis and respirations in order for the plant to be self-sustained and grow providing food and shelter for many animals.

Mesophyte adaptations
Mesophyte plants live in an environment where it is rarely to dry or to wet so there is no need for any major adaptations, which will allow the plant to survive successfully in its environment. Mesophyte plants often have large leaves so that there is a larger surface area available to absorb sunlight in order to carry out photosynthesis. Because they have big leaves they will lose more water as there is a larger surface area for water to evaporate, an adaptation to slow this process down and keep water balance within the plant is the top of the leaf has a waxy cuticle who's function is to slow down water evaporation by trapping water inside the plant. Within the leaf the mesophyll layer of cells is well developed to allow transport of gases with in the plant- carbon dioxide in and oxygen out. The mesophyte plant needs to control the about of water loss in order to keep water balance within the plant as with out water many cellular processes such as cell division and photosynthesis will not be able to occur, as for example water is a raw material needed in the process of photosynthesis.
The vascular bundles within the plant are well developed as water needs to be transported form the roots to the leaves. Vascular bundles contain xylem and phloem, the xylems role is to carry the water from the roots up into the leaves of the plant where the chloroplasts are and photosynthesis occurs the phloem’s role is to carry the organic minerals throughout the plant. The vascular bundles must be well developed in a mesophyte plant as in order for photosynthesis to occur water is needed and water can only be absorbed by the roots so has to be moved up the plant, the water can move against gravity due to the transitional pull and cohesion between the water molecules. Water is also needed at the top of the stem as dividing cells need full vacuoles in order to elongate and divide. The vascular bundles allow the plant to keep water balance as it enables the plant to transport water from the leaves to the rest of the plant where it is then used in many life processes such as photosynthesis and cell division.
The roots of mesophyte plants are well developed and grow deep into the soil this helps anchor the plant and absorb large amounts of water. The roots grow deep into the soil as sometimes water is only found here, the roots also need to cover larger surface areas in order for the plant to absorb sufficient minerals. The plant needs three main minerals in order to survive nitrogen, phosphors and potassium. Water enters the roots through tiny root hairs, which increase the surface area of the root allowing more water and minerals to be absorbed into the plant. Water moves into the plant via osmosis where the water moves from a high concentration of the soil to a low concentration of the root hairs, xylem then transports up into the leafs where is it used in photosynthesis the water is able to move against gravity because the cohesion between the water molecules, which causes water to be pulled up the plant as water is lost via transpiration in the leaves. It is important that new water is being pulled up the plant as minerals such as nitrogen are often dissolved in the water. Roots have adapted to cover large areas allowing the plant to obtain sufficient amounts of water that enables the plant to keep water balance this is a physical adaptation as it involves a physical feature of the plant adapting to keep water balance, so processes such as photosynthesis can occur as water is a raw material needed.
Stomata are where most water loss occurs via transpiration due to factors such as heat and wind. The stomata are only found on the bottom of the leaf as water evaporates upwards so by having the stomata located on the bottom of the leaf on the lower epidermis evaporation will slow down, and water loss will be less as even though the mesophyte plant does live in an environment where water is available the majority of the time if the plant does not control its water loss the it will be unable to keep water balance within the plant, as to much water will be evaporated from the plant. Because of this the stomata stay open all the time in mesophyte plants unless the plant is experiencing extreme water loss due to heat or wind where in these cases the stomata are able to close. Two gaud cells are able control the opening and closing of the stomata. If the guard cells are full of water they will expand opening the stomata, if the guard cells are low in water they will become flaccid and the stomata will close. It is important for the plants to be able to control water loss, as water is needed for the plant to survive if too much water is lost by the plant it will not longer be able to carry out photosynthesis due to water being a raw material for this cellular process. The cells will be come flaccid as the vacuoles will not be filled with water if this occurs the cells will become flaccid and whole plant will begin to wilt and therefore not be able to absorb sunlight for photosynthesis as its leaves will not be high enough and after a wile of this occurring the plant will begin to die
