Photosynthesis

Introduction
You look around yourself and what do you hang? Green everywhere! Grass, bushes, trees and green elucidations! All of these liaisons, obscure from one, produce oxygen which is essential to every living thing on earth. How might they produce oxygen when they are lone(prenominal) leaves that sway in the wind is what you may think, and what exactly is photosynthesis? Photosynthesis is the performance in which set outs take energy from the sun and changes it into their own regimen source or energy, which is sugar, into oxygen for us humans. Photosynthesis starts when light enters a cell of the leaf and is absorbed by chlorophyll, the green blusher in plants that takes in light. Water from the environment also helps in the process of photosynthesis. Electrons from the hydrogen atoms in the water molecules are attracted to the chlorophyll. The hook causes the water molecules to split into oxygen atoms, protons, and electrons. The atoms of oxygen form together into a pair creating oxygen which is then released into the air. In this lab, ninefold groups will conduct a series of experiments as to see what is able to speed up the process of photosynthesis using the environmental temperature, the concentration of water, the wavelengths of light, the presence of carbon dioxide and the concentration of glucose in the system.




Hypothesis
If the plant is submerged in water with a red light shining on it, then photosynthesis will increase.

Procedure
Day 1
* flummox a pre-wired glass oak bottle, rubber stopper and a bank of Elodea to from the lab kit.
* Take a bank of Elodea to the balances located at the center lab station. agglomerate the Elodea to the nearest .01 gram.
* Using forceps, place the massed Elodea strand into the glass oak bottle.
* Using a graduated cylinder, banknote 200 mL of tap water....If you want to get a full essay, order it on our website: Ordercustompaper.com
