Im going to investigate the affect of light on the amount of Pleurococcus. I predict that the side with the least light will have the most Pleurococcus

Pleurococcus

Pleurococcus (a.k.a. Protococcus) is single celled green algae, it is found on the bark of trees but it never grows on softwood trees. It is the most common green algae in the world. It is found is all seasons and grows in moist places. It reproduces by cell division and is transported by the wind. As it is a green plant it photosynthesizes. The formula for photosynthesis is:

6CO2

+

6H2O

-->

C6H12O6

+

6O2

Carbon dioxide

+

Water

-->

Glucose

+

Oxygen

The variables that affect Pleurococcus are:

Abiotic:

> Light (needed for photosynthesis)

> Moisture/humidity: if it is too dry the Pleurococcus will die

> Wind

> Temperature

> Amount of rainfall (and that trickles down the tree)

Biotic

> Position of tree (shading etc.)

> Tree species (some trees have bark that is more suited to Pleurococcus than others)

I'm going to investigate the affect of light on the amount of Pleurococcus.

I predict that the side with the least light will have the most Pleurococcus. This is because
