rates in which certain species’ leaves decay and release the energy stored within them can demonstrate how quickly the energy becomes available to organisms in higher trophic levels. Between plant species the rate of decomposition varies according to leaf structure‚ chemical or physical defence and whether the species is allochthonous or autochthonous. Native species adapt to the predators that feed upon them and the same applies for the predators‚ adapting to the plants defences. Allochthonous species

turned out to have the lowest average water loss per day because transpiration requires some type of driving source (light‚ wind‚ etc) for water to travel from the roots of the plant to the stomata of the leafs. 4.

3 Objective :- To prepare a temporary mount of a leaf peel to show stomata. B) Materials required :- Fresh leaves of plant‚ compound microscope‚ glass slides‚ cover slips‚ water‚ glycerine‚ safranine‚ blotting paper‚ needles‚ brush etc. C) Theory :- i) Stomata are minute pore present on the surface of the leaves. ii) Though they are found on both the upper and lower epidermis of the leaf‚ they are more in number on the lower epidermis. iii)

stomata per unit area of a leaf. The experiment conducted with leaves along a water source and away from a water source was to analyze the stomatal density difference. This experiment was performed to measure which environment had a greater effect on stomatal density. Stomata of a leaf is a miniature pore in the epidermis of a leaf surrounded by guard cells that have a slit which allow movement of gases in and out of the leaf. With stomata‚ when it opens carbon dioxide enters a leaf while water and dioxide
