Nutrition in Plants Test - 3

During photosynthesis, cells containing chlorophyll use raw materials such as carbon dioxide and water to produce food which is stored in the form of carbohydrates.

Autotrophic nutrition is seen in plants. Fungi, parasites and human beings show heterotrophic nutrition.

In the term 'heterotrophic', the word 'heteros' means other and 'trophos' means nourishment.

Photosynthesis is a process by which green plants make use of carbon dioxide and water to produce food in the form of glucose along with the release of oxygen.

Plants require nitrogen for the production of amino acids that make up proteins. Proteins are needed for healthy growth and development of the plant body.

Only non-green plants obtain food through saprotrophic nutrition. Green plants carry out photosynthesis and follow autotrophic nutrition.

Plants prepare their own food by the process called photosynthesis. They make their food from simple inorganic substances like carbon dioxide and water in the presence of sunlight.

Fungi are mostly saprotrophic as they derive their food from dead and decaying organic matter.

Lion, cat, hen and tiger cannot prepare their own food and hence obtain food through heterotrophic mode of nutrition.

The opening and closing of stomatal pores in the leaves is controlled by guard cells.
