Necessary Elements of a Plant

[image courtesy of : Collection of plants]



Chrolophyillic plants needs water,mineral salts, carbon dioxide and light in order to survive efficiently.

Experiment:


* Let some wheat grains germinate under the same conditions(temperature, medium..)
* wait for ten days to obtain wheat seedlings.
* choose plants of th same size and mass.
* Divide them into seperate pots containing the same compost
* Experiment on these plants in order to dertermine the nutritive needs of the chlorophyillic plants by changing one factor at a time (water,time,carbon dioxide)


After doing this experiment, you will realize the importance of light,water, and C02 in order for the plant to survive. Without these necessary elements, the plant will die.



After reading this post and the conflicting articles below, try to answer the following 2 questions

1-What are the basic necessary elements for the developement of a plant?
2-what are the necessary mineral salts for the plant to thrive?
