Explanation: Roots are the underground structures that help in the absorption of water and minerals, provide a proper anchorage to the plant parts, store reserve food material (Carrot, Radish), and synthesize PGR (plant growth regulators). Sometimes roots get modified to perform different functions like Storage of food, respiration, climbing, etc. These types of roots are called modified roots. Examples - prop root of the Banyan tree for providing support, Pneumatophores of Rhizophora, and Mangrove plants for respiration. So, these statements are correct. A. To give support to the plant. C. To store food. D. To absorb water and minerals.

The Nobel Prize for Economics was instituted in 1967 but was first awarded in 1969. The first prize in economics was awarded in 1969 to Ragnar Frisch and Jan Tinbergen "for having developed and applied dynamic models for the analysis of economic processes.

1. Plants release water into the air through a process called transpiration.

2. Transpiration is a natural process, by which plants expel water from their bodies in the form of vapor.

3. The process of transpiration takes place through small holes in the leaves, which are called stomata.

3. Transpiration is essential for plants, as it helps keep plants cool and transport nutrients from the roots to the leaves needed to make food.

Rainwater is the purest form of natural water. It is formed naturally by evaporation followed by condensation of water vapour.
