Answer:
1. Difference between Taproot and Fibrous root
Taproot consists of one large long root, while this is not the case for the fibrous root.
Taproot penetrates deep into the soil, while a fibrous root is shallow and does not penetrate as deeply.
A taproot is the differentiated primary root of the plant, while the fibrous root is not the differentiated primary root of the plant.
In the fibrous root system the primary root is eliminated, this is not the case in the taproot system.
2.The process of vein formation on the leaf is known as venation. The two types of venation are
°Reticulate venation
°Parallel venation
3.Significance of photosynthesis
- Photosynthesis is a physiological process that is an ultimate source of oxygen and energy for all living organisms.
- It provides food for all living beings but the process occurs in the leaves of green plants.
- It fixes and balances the amount of carbon dioxide and oxygen in the atmosphere by plants exhaling oxygen and animals and humans exhaling carbon dioxide.
- It helps in the synthesis of organic compounds from inorganic compounds.
- It provides nutrition to the plants and thus helps in their growth and development.
4.Reticulate Venation
Parallel Venation
R=Veins in this case are arranged as a network or web-like structure.
P=Veins run parallel to one another along with the leaf from base to tip.
R=This pattern is typical in dicotyledonous plants.
P=It is mostly found in monocotyledonous plants.
R=For example, rose, mango, hibiscus, ficus, etc.
P=For example, wheat, maize, grass, bamboo, banana, etc.
5.The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water
