A essay of how light intensity affects the rate of photosynthesis

Actually, most places on Earth have the same amount of carbon dioxide in the atmosphere, but a plant can only get it by opening holes in its leaves. These holes are too small for you to see without a strong microscope, but they are big enough to let water vapor out of the plant.

This mean it will absorb any wavelength of light which is not in the green spectrum of light.

Biology - How Light Intensity Affects the Rate of Photosynthesis

There are many complicating interactions between plants and light. The process of converting carbon dioxide taken from air and water from the soil into complex substances like glucose, is called photosynthesis and can A limiting factor could be the amount of chlorophyll molecules that are absorbing the light.

The reason in which I will keep the other variables the same is because if increased they would increase the rate of photosynthesis making the experiment pointless and a waste of time. Light is an extremely important factor for the process. When this occurs, leaves can experience sunburn damage.

Plants can absorb and use light energy because they have a green pigment, chlorophyll, contained in the chloroplasts in some of their cells. With too little light, photosynthesis cannot occur either and the plant suffers without the production of sugars.

I am not sure what you mean by "level" of light, but I will answer your question in to ways - in terms of the intensity of light and wavelength of light. That is why plants are called autotrophs or simply "self - feeders".

An investigation in being carried out to see whether the support of different carbon sources have an adverse effect on the growth rate of yeast cultures.

Research question Due to the fact that most plants have no appropriate apparatus to ingest and digest food, they have to obtain it by themselves using simple ingredients. We will be doing each light intensity test three times to get an average for our graphs. The equation for photosynthesis can help to predict the outcome of the investigation.

How can you look at a landscape and tell whether a lot of photosynthesis usually happens there? So by level of light you probably mean light intensity which is something that can be measured.

Are there any sugars that yeast cannot metabolize? The amount of carbon dioxide CO2 produced by yeast in various conditions independent variables: Photosynthesis needs light, but it also needs other things, and too much light can create heat and dryness that are bad for photosynthesis.

Apparatus The apparatus I will be using are:How Light Intensity Affect Photosynthesis Essay example; How Gender Affects the Workplace Essay. How Gender Affects the Workplace There have been studies, debates and misconceptions on the differences between men and women.

Aim: To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Introduction: The. At a light intensity of 50 arbitrary units for the shade grown plant, and arbitrary units for the light grown plant, the rate of change in CO2 levels was a negative value (, ).

This implies that the net rate of photosynthesis was greater than the. Investigation on how light intensity affects the rate of Photosynthesis Essay Sample Introduction: Photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose, which provides a basic energy source for the plant.

Factors Affecting The Rate Of Photosynthesis Biology Essay. Print Reference this. Published: 23rd March, The hypothesis was that the rate of photosynthesis would increase if the light intensity and NaHCO3 levels were increased (please refer to Graph1).

The rate increases at a steady rate as the light intensity increases until near the. The reason that light intensity does affect the rate of photosynthesis is because as light, and therefore energy, falls on the chloroplasts in a leaf, it is trapped by the chlorophyll, which then makes the energy available for chemical reactions in the plant/5(1).
