The Process Of Photosynthesis Essay

1237 words - 5 pages

Photosynthesis is the process undergone by plants consisting of a series of chemical reactions that require four factors; water, carbon dioxide, radiant energy and temperature using chlorophyll molecules to trap radiant energy from the sun resulting in the making of glucose and oxygen as bi-products. The process of photosynthesis provides plants with the food and energy they need to grow. Plants that produce their own food are called autotrophic plants. Not only do these plants make food for themselves but they also serve as primary producers. Without photosynthesis the oxygen levels in the atmosphere would not be replenished. The process of photosynthesis is divided into two main parts. The first phase is the light dependent phase which happens in the grana of chloroplast. This reaction happens when the light energy is absorbed by chlorophyll and then changes the light energy to chemical energy. The energy of these energized electrons is now used to split water molecules. Thus leading to oxygen being released from the plant as a bi-product. The light dependant phase, otherwise known as the Calvin Cycle occurs in the stroma of chloroplasts. In this process NADP.H is fixed with carbon dioxide to make glucose. Sunlight is a necessity for the process of photosynthesis to occur. My aim in this investigation is to test the necessity of light for the process of photosynthesis.
Energy from the sun is lost in our atmosphere through many factors. The energy that is able to stay is just enough for plants to use in the process of photosynthesis to make and store energy in the form of sugar molecules. The plant does not use all the light that gets to it. It only uses certain colours of the light spectrum to enable the process of photosynthesis to take place. Plants absorb mostly red and blue wavelengths. The colour you see is the colour being reflected. Green plants do not absorb light from the green range, they reflect the green rays. The process of photosynthesis occurs in the chloroplast. The chlorophyll is what captures the light from the Sun. We'll talk about it in a bit, but the chloroplasts are working night and day with different jobs. The molecules move about and change in the stroma. Chlorophyll is a varied compound. There are four types: a, b, c, and d. Chlorophyll is found in many microorganisms and even some prokaryotic cells. But in plants, the chlorophyll is found in the chloroplasts. The other molecules are water, carbon dioxide, oxygen and glucose. Carbon dioxide and water undergo a chemical reaction with light to create oxygen and glucose as bi-products. The glucose produced is used in many ways. Either stored, used as energy or consumed and used up by other organisms.
The food producers of the cells in plants are the chloroplasts. They are found in no other organisms except some protists. All green plants are working to convert the energy of the sun into sugars and the oxygen we breathe. Plants are the basis of all life on Earth. That...

745 words - 3 pages there is a need for large amounts of blood in peripheral tissue such as skeletal muscle. In order to fulfill this need blood is stunted from the gastrointestinal tract resulting in reduced digestive activity. For the most part salivation ceases and the mouth becomes dry. Secretion of saliva is under the parasympathetic system. The parasympathetic system also stimulates the production of digestive enzymes and the process of digestion which in turn

The equation for photosynthesis is: [IMAGE] How photosynthesis works. The process mainly takes place inside the cells of plants, mainly in the leaves. Firstly the plant needs water; this is absorbed from the soil, through the roots and is carried up the stem by

How does light intensity affect the rate of photosynthesis?

2729 words - 11 pages photosynthesise, plants need light. It provides the energy for the process to happen. Chlorophyll is an enzyme and it speeds up the reaction. If a plant does not get enough of either of these things, photosynthesis will not happen as quickly, if at all. Therefore, I predict that when the light is not very intense we will not see so many bubbles being produced. This is because the plant will not have so much energy (derived from light) to activate
