plant photosynthesis

Carbon Dioxide - During photosynthesis, carbon dioxide is converted into carbohydrates and this is called fixing of carbon dioxide. Many processes like respiration, combustion, volcanic activity, etc. release carbon dioxide into the atmosphere. This carbon dioxide of the atmosphere is use..

Factors Affecting Photosynthesis - External Factors - Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis..

Take a potted plant and destarch it by keeping it in darkness for 24 hours. To one of the leaves attach a piece of metal foil or paper on both sides. Leave the plant in sunlight for 48 hours. Then take the leaf and remove its metal foil. Decolourise the leaf as in the above exp..

Take a few healthy twigs of Hydrilla, a water plant. Place it in a funnel and invert the funnel in a beaker of water. Invert a test-tube over the stem of the funnel. Leave the set-up in sunlight. After sometime, bubbles can be seen rising in the test-tube. Remove the test-tube caref..

Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is limited by the most limiting facto..

Take a potted plant. Destarch it. Insert one of its leaves in a bottle containing potassium hydroxide (KOH) solution as shown in the figure. KOH absorbs all carbon dioxide in the bottle. Leave the set up in sunlight for 48 hours. Test the leaf for star..

In plants, breakdown of substances is much slower than in animals. Hence accumulation of waste is much slower and there are no special organs of excretion. Green plants in darkness or plants that do not contain chlorophyll produce carbon dioxide and water as respirato..

Most plants are autotrophic. They synthesize their own food. The green plants, also called the producers, trap the solar energy and convert it into chemical energy of the food. The biochemical reactions in the body which result in the formation of chemical compounds are collecti..

Leaves are large and alternate. Petiole is tendrillar. The lamina proper is modified into a large pitcher, the leaf apex serving as lid. Nepenthes or Pitcher Plant The pitcher attracts insects due to its gaudy colour and nectar. The insects roam into neck of pitcher in search of more nect..
