The leaves of a plant can synthesise food because they contain a green pigment chlorophyll (which is necessary for making food). On the basis of their modes of nutrition, all the organisms can be divided into two main groups: Those organisms which can make food themselves from simple substances (like carbon dioxide and water) by the process of photosynthesis, are called autotrophs (and their mode of nutrition is called autotrophic). The. List the three components necessary for photosynthesis to take place 3. The plants use the energy in sunlight to prepare food in the presence of a green colour matter called “chlorophyll” present in the leaves of a green plant. Vitamins are contained in vegetables, fruits and cereals made by plants. The stomatal pores of leaves open only when carbon dioxide is to be taken in or oxygen is to be released otherwise they remain closed. Photosynthesis requires CO2+ Water H2O and sunlight. organelle where photosynthesis takes place. But remember, you still have to water them! by shinyrichy. Photosynthesis: Discovery!

Proteins are nitrogenous substances which contain nitrogen element. stagnant parts of a river . Answer: Glucose and oxygen are the final products after photosynthesis. The green colour of algae is due to the presence of chlorophyll in them. The plants also need minerals to make foods other than carohydrates. chlorophyll. We see patches of slimy, green layer floating on the surface of a pond or lake, or even in the stagnant parts of a river . Plants combine some of the glucose carbohydrate made during photosynthesis with nitrate minerals(obtained from soil) to make amino acids which are then made into proteins.In this way, plants make proteins as food. Photosynthesis and Cellular Respiration - Marietta Middle â¦ Start studying Photosynthesis - 7th grade Science. The final products of photosynthesis are oxygen and glucose. 7th Grade Science Mr. McAninch Photosynthesis Worksheet 1. In the absence of photosynthesis, there would be no oxygen in air and hence no animals could exist on this earth. Nitrogen has no role in process of photosynthesis. Edit. The green plants produce food for non green plants as well as for animals. Oxygen gas is produced during photosynthesis which is utilised by all the living organisms for their survival. In photosynthesis, light energy is converted to chemical energy and stored in the form of food sugars. 6 hours ago. Option C is oxygen which is the right answer.

Learn how solar energy is turned into chemical energy and how plants create glucose, their main source of fuel. (3) Role of chlorophyll in Photosynthesis – It is the presence of chlorophyll which makes the leaves look green. Chlorophyll is present in every leaf of a plant in the form of hundreds of tiny structures called chloroplasts. Photosynthesis is fundamentally important for life on Earth as it provides the oxygen on which all other life depends and as the ultimate source of food and energy in all ecosystems. The non green plants called fungi are heterotrophs. 3. 4) The role of Sunlight in photosynthesis – The sunlight supplies energy for the food making process called photosynthesis. The sunlight energy absorbed by chlorophyll is used to combine carbon dioxide and water in the green leaves to produce food. The plants also obtain nitrogen from the nitrogen fertilisers.
