The Rate of Photosynthesis

Planning

Aim:

I am going to investigate effect of light intensity on the rate of photosynthesis.

Introduction:

Photosynthesis is the process by which plants, some bacteria, and some microorganisms use the energy from sunlight to produce sugar, which cellular respiration converts into the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen and the food that we absolutely must have to stay alive.

6H2O + 6CO2 ----------> C6H12O6+ 6O2

The above chemical equation translates as:

Six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen

Leaves and Leaf Structure

Plants are the only photosynthetic organisms to have leaves (and not all plants have leaves). A leaf may be viewed as a solar collector crammed full of photosynthetic cells.
