The diagram shows the process of photosynthesis. Summarize the information by selecting and reporting the main features.
SAMPLE ANSWER
The illustration delineates the daily botanical process which transforms the solar energy into chemical one: sugar.
Overall, the photosynthesis requires a combination of several steps to afford the high demand of energy and ingredients.
The first occasion of the photosynthesis is the opening of stomata on leaves surface to gather the excessive volatile in the earth atmosphere: carbon dioxide. Noticeably, this process can only occur during the day when the sun is shining, due to the light stimulation on the activity of the stomata.
Moreover, not only does the sunlight activate the gas collecting of the leaves but also it provides the leaves with electron energy for the chemical reaction initiating the sugar when the red and blue lights are absorbed by the pigments- chlorophyll. Consequently, the green wave lengths absorption from the sun of leaves are trivial, which explains why the plants have their natural green colour.
Simultaneously, at the root of the tree, the water from the soil is absorbed actively through the root surface. Water is then, thanks to physical and chemical forces in the plant, flowing to the xylem of the root to reach other orgasms of the plant. This multi-purpose ingredient takes joint in the sugar making procedure. During that procedure, oxygen is created and together with the volatile water, they are released into the air through the opening stomata.
The transpiration- the water loss, is not the threat of the botanic life but an essential process needed for water transition in the plant. Once the solar energy is completely transformed into chemical- the sugar is made, the excess is, therefore, preserved as starch in the roots to provide the energy for plants wheel of life.
