Both are involved in the light reaction of photosynthesis.

Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

I believe this will happen because when the light source is nearer to the plant more of the plants surface area is coming in to contact with the light from the desk lamp therefore more photosynthesis will occur which will mean more oxygen will be produced which will create more bubbles....


Importance of Light in Photosynthesis (Theory) : Class …

The following video clip is an explanation of the importance of photosynthesis.

Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (singular: stoma. plural: stomata)

The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf. This also allows the oxygen produced in photosynthesis to leave the leaf easily.




Carbon dioxide is present in the air we breathe, at very low concentrations. Even though it forms about .04% of the air, it is a needed factor in light-independent photosynthesis.

In higher concentrations, more carbon is incorporated into carbohydrate, therefore increasing the rate of photosynthesis in light-independent reactions.


The light-independent reactions of photosynthesis ..

The further away the light, the slower the oxygen bubbles will be produced so the less light the less photosynthesis will occur which is needed for the plant to make food....

Light has a particulate nature and a wave nature

Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.

BBC - Higher Bitesize Biology - Photosynthesis : Revision

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

BBC - GCSE Bitesize: Photosynthesis

With too little light, photosynthesis cannotoccur either and the plant suffers without theproduction of sugars. There are many complicatinginteractions between plants and light. I hope thatyou continue to investigate this as the story getsmore interesting and exciting the deeper you go.

The light-dependent reactions (article) | Khan Academy

There are four things that are required by the plant before it can carry out photosynthesis, they are light, chlorophyll, carbon dioxide and water ....

The granum (plural grana) is a stack of which contains the photosynthetic pigments; this is where the light dependent stage takes place:
