Photosynthesis Essay example - 598 Words

Photosynthesis Green plants are producers. This means that they can survive without animals! They can make lots of organic chemicals from a few simple inorganic chemicals. They need simple things like carbon dioxide and water and can make complex things like sugar, starch, fat, and proteins. Plants get their nutrients from the environment. Carbon dioxide comes from the air (unless they are aquatic plants, in which case they get it from the water surrounding them). They get water from the soil. They also need other inorganic nutrients like nitrate, sulphate and phosphate. A few plants cannot get nitrate out of the soil so they have to eat animals to get the nitrogen which they must have for†¦show more content†¦In photosynthesis, light energy is converted into chemical energy. When animals and plants respire, the chemical energy in glucose can be converted into other forms of energy e.g. kinetic energy. Plants can make enough glucose on a sunny day to last them through the night and through lots of cloudy dark days, but they cannot store up lots of glucose. What they do is convert the extra glucose into starch. When they need to use the energy, they can turn the starch back into glucose. Starch can be stored in leaves or other parts of the plant. they can turn glucose into sucrose: this is a sugar carried around the plant in special tubes called phloem. Photosynthesis results in an increase in biomass; i.e. there is more carbohydrate in the plant. They can turn some of the glucose into fat or protein. They have to make lots of different chemicals to grow, but the two most important ones are fats and proteins. To do this they need energy (growth requires energy from glucose). Plants also have to make a very special chemical called DNA: this is the hereditary chemical of all animals and plants. They must also make lots of new chlorophyll. Like carbohydrates, fats also contain three elements:  · Carbon  · Hydrogen  · Oxygen Proteins contain four or five elements:  · Carbon  · Hydrogen  · Oxygen  ·Show MoreRelatedPhotosynthesis769 Words   |  4 Pages___________________ Class ____________ Photosynthesis Virtual Labs Tutorial: http://www.harcourtschool.com/activity/science_up_close/512/deploy/interface.html Watch and listen to the tutorial found in the link above.

There are two basic processes in photosynthesis: light-dependent and light-independent. Light-dependent process, a temperature-independent reaction where light energy is absorbed by the photosynthetic pigments and transformed into chemical energy which is used for water, splitting into oxygen molecule, proton (H+) forRead MoreThe Effect Of Photosynthesis On The Environment Of Photosynthesis1106 Words   |  5 PagesPhotosynthesis is defined as the process by which green plants manufacture their food (organic compounds) making use of carbon dioxide and water in the presence of sunlight. It is also the synthesis of carbohydrate from sunlight, water and CO2 by the green plants. It is an endergonic and anabolic process. Bacteria show an oxygenic photosynthesis as they do not use water and do not evolve oxygen. Cyanobacteria (blue green algae) evolved oxygen first time in evolution as they show oxygenic photosynthesisRead MorePhotosynthesis And Cellular Respiration. Photosynthesis1032 Words   |  5 PagesPhotosynthesis and Cellular Respiration Photosynthesis and respiration are reactions that complement each other in the environment. In reality, they are the same reactions, but they occur in reverse. During photosynthesis, carbon dioxide and water yield glucose and oxygen. Through the respiration process, glucose and oxygen yield carbon dioxide and water. They work well because living organisms supply plants with carbon dioxide, which undergoes photosynthesis and produces glucose, and these plantsRead MoreThe Effect Of Photosynthesis On The Rate Of Photosynthesis1660 Words   |  7 PagesAbstract: During photosynthesis plants take light energy and turn it into chemical energy. The purpose of the study was to test the effect of various lighting conditions on the rate of photosynthesis. In this experiment the rate of photosynthesis is measured by timing how long it takes photosynthesis to occur in ten leaf disks that are in a solution of carbon dioxide. The prediction for this experiment was that if a plant receives more l ight, then it will have a higher rate of photosynthesis. The data supportsRead MoreThe Effect Of Photosynthesis On Plants And The Cycle Of Photosynthesis899 Words   |  4 Pagesramifications and effects it has on plants and the cycle of photosynthesis. Pollution not only directly effect plants and the cycle of photosynthesis, but pollution can also indirectly harm other elements that contribute to the life of a plant and the cycles it performs. Photosynthesis is the cycle in which light energy converts carbon dioxide and water into glucose and oxygen by ways of a chemical reaction (Robinson 2015). Photosynthesis’, overall a fairly simple process, has couple complex reactionsRead MoreLight and Photosynthesis1133 Words   |  5 Pagesresearch task project I have decided to see if light is necessary for photosynthesis to take place in green plants. I choose this topic because I wanted to see if light necessary for photosynthesis is really. It is also a very interesting topic because most living things need light to function, survive and grow. Photosynthesis is the physic-chemical process by which green plants use light energy to photosynthesis. When Photosynthesis occurs it takes in the co2 from the atmosphere and releases oxygenRead More Photosynthesis Essay455 Words   |  2 Pages Photosynthesis nbsp;nbsp;nbsp;nbsp;nbsp;Photosynthesis is the most important part of the lively hood of humans and animals. Without photosynthesis we would not be able to receive energy. We should be more appreciate of plants, without them we would not survive.

Photosynthesis takes place in all plants that contain chlorophyll. Photosynthesis mainly takes place in the palisade mesophyll cell in the leaves of plants. The main reaction is to produce oxygen and glucose, glucose is stored in the form of starch and does not affect osmosis, taking place in the plantRead MoreThe Process of Photosynthesis1016 Words   |  5 PagesPhotosynthesis 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
