Light and photosynthesis essay

This can be measured through the amount of glucose that is produced by a plant over a given period of time.

Light and photosynthesis essay

Effect of Light Intensity on Photosynthesis By: Felices Botany 1 Sec. X-5L April 13, A scientific paper submitted in partial fulfillment of the requirements in Botany 1 laboratory under Ms. The rate of photosynthesis of the plant was determined using bubble counting method.

The bubble is the oxygen produced during the process. The set-up was placed in three areas with different light intensities, with darker light, low light, and strong light.

The number of bubbles observed in the control is less than the observed bubbles in the low light.

Types of photosynthesis

Also, the bubbles in the low light are less than those in the strong light. It is the process in which solar energy is converted into chemical energy.

Therefore light is actually one of the essential factors in the process of photosynthesis. Light intensity is the rate at which the light spreads over a surface of a given area. Light is one of the external factors that affect the rate of photosynthesis.

The rate of photosynthesis is directly proportional to light intensity Kent, The Hydrilla sprigs was placed in a large glass funnel such that their freshly cut ends are towards the stem of the funnel.

Effect of Light Intensity on Photosynthesis

The test tube was filled with water and was carefully inverted over the funnel stem. The oxygen given off by the photosynthesizing sprigs appears in the form of bubbles.

A relative estimate of the process of photosynthesis was made by counting the number of bubbles coming out of the funnel regularly per minute time. Next, the set-up was illuminated with strong light high light intensity. And lastly, the light was put off then the set-up was transferred to a darker part of the room inside a box.

Observations were made and recorded.Light and Photosynthesis Essay the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise. It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch.

Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration.

In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide.

Research Papers on Photosynthesis Photosynthesis Research Papers explore the process that is necessary for plants to survive. Photosynthesis is a complex process of how sunlight is turned into engery for plants. Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide, affected the rate of photosynthesis.

The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). Photosynthesis in Elodea Lab Essay. Elodea & Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.

Photosynthesis: Essay on Photosynthesis ( Words)
