Photosynthesis (explained)

One of the most common producers is green plants.  These organisms absorb light energy from the sun or chemical reactions to convert carbon dioxide to organic matter.  Green plants can also use water to convert carbon dioxide to organic compounds such as sugar glucose.  The result of this is that it releases oxygen as a by-product.  This process driven by light energy is photosynthesis.  Using the method of photosynthesis, plants are able to create every complex organic molecule which form their body by using mineral nutrients such as sulphur, phosphorus, potassium and nitrogen which can be retrieved from either soil or water.

A green pigment called chlorophyll is one of the molecules that are used to absorb light energy in photosynthesis.  It is obvious to be able to identify which plants photosynthesise by looking at they’re colour.  If it is green, then it photosynthesises.  Some examples of these types of plants include the beach grass, shrubs, and maritime forest plants found on Plum Island.

There is a huge range of plants that can photosynthesise, whether it be microscopic bacteria or extremely large trees.  In every ecosystem, there are always active producers that photosynthesise.

AIM

The aim of this experiment will be to test the rate of photosynthesis using Gardenia Augusta Magnifica in a warmer environment against a cooler environment.

HYPOTHESIS

The rate of photosynthesis in a warmer environment will be faster than the rate of photosynthesis in a cooler environment.

VARIABLES

Dependant:

The rate of photosynthesis

Independent:

The ...
