4. List four changes that takes place in our body.
5. What are the functions of a roots?​

Answer 1

Answer:

wheat - reticulate venation

tulsi - parallel venation

banana - parallel venation

banayan - reticulate venation

Explanation:

because the leafs prepare food for the plants..

the leafs store the food as glucose

because they release carbon - dioxide

Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.

air becomes lighter, rises up, evaporation, then condensation

The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive. Plants provide food for all life on the planet.

3) Parallel venation : Wheat and banana.

Reticulate venation : Tulsi and banyan.

====================================

4).

Leaf contains a green pigment called chlorophyll. With the help of this chlorophyll, the plants prepare their food in the presence of water, sunlight and oxygen. Hence, leaf is called the kitchen of a plant cell.

We feel cool when we sit or stand under tree. Trees also cool the air by a process known as 'transpiration cooling '. As trees release water into the atmosphere from their leaves via transpiration, the surrounding air is cooled as water goes from liquid to a vapor.

• Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
