NCERT solutions for class 10 science - Nutrition in Plants

In this article, the following topic “Nutrition in the Plants” from Class 10th Science-Biology is discussed.
Nutrition in the Plants
  • Green plants are autotrophic and synthesize their own food by the process of photosynthesis.
  • The process, by which green plants make their own food from carbon dioxide and water by utilizing sunlight energy in the presence of chlorophyll, is called photosynthesis.
  • Oxygen is released during photosynthesis.

Raw materials for photosynthesis: 
The raw materials for photosynthesis are:
  1. Carbon dioxide
  2. Water

How the plants obtain carbon dioxide?

  • There are a large number of tiny pores called stomata on the surface of the leaves of plants.
  • The carbon dioxide gas enters the leaves of the plant through the stomata present on their surface.
  •  Each stomatal pore is circumvented by a dyad of guard cells.
  • When water flows into the guard cells, they swell, become bend and cause the pore to open.
  • On the other hand, when guard cells lose water, they contracts, become straight and close the stomatal pores.

How the plants obtain water for photosynthesis:

  • The water necessitates by the plants for photosynthesis is absorbed by the root of the plants from the soil through the process of osmosis.
  • The water absorbed by the roots of the plants is conveyed upward through the xylem vessels to the leaves where it reaches the photosynthetic cells.
  1. The plants also need other raw materials such as nitrogen, phosphorus, iron, and magnesium, etc., for building their body.
  2. The plants take these materials from the soil.
  3. Nitrogen is an essential element used by the plants to make proteins and another compound.

When there is only one of a naming word (noun), it is said to be a  singular noun . When a noun shows more than one, it is said to be in the  plural . We can add  –S, -es, -ves or ies  to show that there is more than one noun.  For example,  we say many birds, four biscuits, six brushes.
