Investigate one of the limiting factors on rate of photosynthesis in a water plant

INTRODUCTION

Photosynthesis is the process by which plants make their own food for photosynthesis to occur the plants need sunlight energy, the energy is absorbed by a green pigment called chlorophyll which is found in the leaves. This energy then combines with water molecules from the soil, and carbon dioxide from the air. Then as a result of this a type of sugar called glucose is produced and oxygen is made.

The equation for photosynthesis is

6co2 + 6H2oc6 H12 o6 + 6o2

There are certain things that affect photosynthesis and these are called limiting factors. Things like light intensity can affect the rate of photosynthesis- we call them limiting factors.

It doesn't matter if the plant has lots of carbon dioxide and a nice warm temperature. If light is in short supply, then light will limit the rate of photosynthesis

Let’s say light intensity is limiting photosynthesis, the only way to increase the rate is to increase the limiting factor. In this case light intensity.

Other limiting factors are carbon dioxide and temperature. But only one factor can limit the rate at any one time. It depends on which one is in the shortest supply.

I will not be testing the rate of photosynthesis in a water plant with carbon dioxide as it is too vague a subject to do and stimata is too difficult. So that leaves me with the choices of heat and light, I think that heat will be hard to do as I will find great difficulty in keeping the temperature exactly right every time, so I think for sheer easiness I will chose light distance as my variable.

PREDICTION

I predict light affects the rate of photosynthesis because photosynthesis is light splitting water molecules from hydrogen and oxygen ...
