Meaning of Photosynthesis 2. BIOLOGY (231/2) Revision Questions (Essays): Expected Responses Significance of Photosynthesis to Mankind 3. Yet another product formed as a result of photosynthesis is fossil fuel. Photosynthesis happens during the day time because the plants require sunlight to produce energy. This allows reactions to occur under conditions that sustain life: An enzyme is simply a catalyst; also something extra that’s only purpose is to speed a process up that would otherwise take a very long time. It breakdown the food which is through photosynthesis process. Photosynthetic Apparatus 5. History 4. Photosynthesis takes place in all plants that contain chlorophyll. Source […] Plant also become pale. Here are KCSES 2020 Biology Essay Questions and Answers (KCSE 2020 Prediction Questions). Photosynthesis & cellular respiration are the main pathways of energy flow in living things. There are … The energy released from the plants, millions of years ago as a result of photosynthesis, after further geological processes get converted to fossil fuels (i.e., coal, oil, and gas). Top writers. Pigments 6. Plant photosynthesis was stable for hundreds of years before the industrial revolution, but grew rapidly in the 20th century, according to new research published today in Nature. ADVERTISEMENTS: In this essay we will discuss about Photosynthesis in Plants. Defective Photosynthesis Symptoms – In this process sunlight is very important. There are many reasons why photosynthesis is important to humans, plants and animals, but the most important is the production of oxygen in the atmosphere. Photosynthesis Photosynthesis produces energy in the form of glucose it uses water from the soil, carbon dioxide from the air, and energy from the suns light. Without photosynthesis, the atmosphere would not have enough oxygen to support humans, animals and even plants, which also require oxygen. Mechanism 8. Fossil Fuel – A By-Product of Photosynthesis. Photosynthesis is a long process but it is need for most life on planet earth. The food which is made by the photosynthesis process, respiration takes energy from it. The light independent reactions use that chemical energy and carbon dioxide to build stable long-term energy storage molecules like glucose and other carbohydrates. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions, such as those in photosynthesis or glycolysis. When plants respire, they take in carbon dioxide from the air which aids them in preparing food (glucose). On the other hand, respiration happens all the time as long as a living creature is alive. Essay on Photosynthesis 704 Words | 3 Pages. The byproduct of photosynthesis has oxygen in it, and is need for human survival as well as other animals to live on earth. Evidences for Existence of Light and Dark Reactions 9. Photosynthesis is a process in plants, algae, and some prokaryotes, that coverts solar insulation into chemical energy stored in glucose or other organic compounds. Photosynthesis occurs in slightly different ways in higher plants relative to photosynthetic bacteria. Words: 495 Length: 2 Pages Document Type: Essay Paper #: 93561218. The process for photosynthesis is long but is needed . Content: 31 pages with 60 questions and answers. Light depended reactions occur inside the thylakoids. Photosynthesis is a process by which plants and some other organisms convert, light energy from the sun, CO2 from the air & H2O from the earth, into chemical energy stored in molecules like glucose. After reading this essay you will learn about: 1. Quantum Requirement and Quantum Yield 7. If the defective problem on plant photosynthesis, the colour of the leaves will change.
