A essay of how light intensity affects the rate of photosynthesis

So water is an important limit on a plant. What is the optimal temperature for yeast to metabolize sugars? Plants can absorb and use light energy because they have a green pigment, chlorophyll, contained in the chloroplasts in some of their cells. 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.

The light intensity will be changed for it is the only variable used in the experiment. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Light intensity is usually defined as the energy hitting an area over some time period. 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.

Biology - How Light Intensity Affects the Rate of Photosynthesis

What is the optimal concentration of sugar in 60 mL of water for yeast? Photosynthesis needs water, carbon dioxide, chlorophyll, light, and the right temperature. Prediction I predict that as the input variable, the light intensity increases the light moved towards the plant the outcome variable, the amount of oxygen, produced from photosynthesis will be larger.

Investigation on how light intensity affects the rate of Photosynthesis Essay Sample

Chloroplasts act as a energy transducers, converting light energy into chemical energy. 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.

Photosynthesis needs light, but it also needs other things, and too much light can create heat and dryness that are bad for photosynthesis. With too little light, photosynthesis cannot occur either and the plant suffers without the production of sugars.

When this occurs, leaves can experience sunburn damage. To investigate the difference in growth rates between yeast cultures that have been grown in different carbon sources.

If there is enough water, carbon dioxide, and the temperature is right, light becomes the factor which will affect photosynthesis. Also if they decrease then it will be likely that the rate of photosynthesis will decrease as well. 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.

Then it will start decreasing and be very low almost 0 through the nm green light and then it will increase again peaking at about nm red and yellow light. The amount of carbon dioxide CO2 produced by yeast in various conditions independent variables: 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.

The process of converting carbon dioxide taken from air and water from the soil into complex substances like glucose, is called photosynthesis and can Oxygen is a waste product. More light can mean more photosynthesis.

Whats more, different types of carbohydrates release various amounts of energy during fermentation. How does the level of light affect the rate of photosynthesis? Chlorophyll is a green pigment in the chloroplast of the plant cell which absorbs the light.

Though the temperature, watt of the bulb, amount of water, size of the plant and position of the clamp and stand. That is why plants are called autotrophs or simply "self - feeders". 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.

Are there any sugars that yeast cannot metabolize? This is a very important aspect of photosynthesis. Light is an extremely important factor for the process. We will be doing each light intensity test three times to get an average for our graphs. When we think of photosynthesis as a process, we can see that there are at least three things that can limit the process: The equation also shows that if there is more light energy then more glucose and oxygen will be produced.

At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant. If you look at a spectrum from nmnm.

The final products of the anaerobic respiration are nutrients, ethanol and carbon - dioxyde. Thanks for asking, Answer 2:Biology - How Light Intensity Affects the Rate of Photosynthesis This Research Paper Biology - How Light Intensity Affects the Rate of Photosynthesis and other 64,+ term papers, college essay examples and free essays are available now on mi-centre.com Autor: review • November 19, • Research Paper • 2, 4/4(1).

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.

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.

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).

Biology Coursework ¡V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process.
