The carbon dioxide gas present in air enters the leaves of a plant through the stomatal pores present on their surface and utilised in photosynthesis. Plants take in oxygen and give out carbon dioxide. In the absence of photosynthesis, there would be no plants on this earth and hence no animals will survive. The sun’s energy is captured by plant leaves with the help of chlorophyll and converted into chemical energy of food. Question 15 What is the role of sunlight in photosynthesis? plants use the simple carbohydrate glucose to make many other foods such as starch, oils (or fats), proteins and vitamins. (2)The glucose carbohydrate then gets converted into a complex carbohydrate called Starch. Last Updated on March 20, 2019 By Mrs Shilpi Nagpal.

(i) Taken in : (3) Role of chlorophyll in Photosynthesis – It is the presence of chlorophyll which makes the leaves look green. Carbohydrate which is produced in the process of photosynthesis is ultimately converted into starch and stored in leaves. The opening and closing of stomatal pores in the leaves is controlled by the guard cells. The seeds or grains of wheat and rice have a lot of starch in them. The presence of carbon dioxide, water, chlorophyll and sunlight is necessary for the process of photosynthesis to take place. … Sometimes when we do heavy exercise, anaerobic respiration takes … Question 9 Why is it always advised not to play with fireworks? (v) Chlorophyll: contained in leaf (4)Some of the glucose is also converted into other types of plant foods such as fats and oils, proteins as well as vitamins. 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. (1) How the plants obtain Carbon Dioxide for photosynthesis – The plants take carbon dioxide gas from air through the tiny pores (called stomata) present on the surface of leaves.Each pore is surrounded by a pair of guard cells. Carbon dioxide + Water ————–> Glucose + Oxygen. Which of these gases is Suzanne likely to inhale the most? The Questions and Answers of What is the equation of photosynthesis.? Write the overall chemical equations of the two kinds of respiration in plants. The green colour of algae is due to the presence of chlorophyll in them. Proteins are nitrogenous substances which contain nitrogen element. This green layer is formed by the growth of tiny green plant-like organisms called algae . 1 Photorespiration, usually occurs in A One cell organelle. Do plants need oxygen ? Oxygen gas is produced during photosynthesis which is utilised by all the living organisms for their survival. Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2. Go To Download Page Close.

Any activity inside the cell is carried out by the energy released by these ATP molecules. (c) Stem The tiny, pipe-like vessels which transport water from the roots of a plant to its leaves are called xylem. Algae are a large group of simple, plant-like organisms. So, photosynthesis also takes place in leaves having colour other than green. 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). Vitamins are contained in vegetables, fruits and cereals made by plants. B Two cell organelles. The methods of obtaining food are called modes of nutrition. If the answer is not available please wait for a while and a community member will probably answer this soon. The leaves of a plant can synthesise food because they contain a green pigment chlorophyll (which is necessary for making food). The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. If so, what is its source ? Answer: The process of making food in plants is called. Human beings and animals depend on plants for their food, directly or indirectly. Describe the phenomena of transpiration, photosynthesis and cellular respiration 2. 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. Photosynthesis - Test 1.
