Root

Roots play a vital role in the function and anatomy of plants. They absorb water and nutrients, anchor the plant to the ground, store food and nutrients, and form symbiotic relationships with fungi and other organisms. The root system architecture (RSA) refers to the spatial configuration of a plant’s roots, which provides a secure supply of nutrients, water, and support. RSA is regulated by genetic and environmental factors, and the growth of roots is influenced by factors such as light, gravity, and physical barriers. Different types of roots exist, including primary, secondary, adventitious, and aerial roots, each with their own characteristics and functions. Roots also have important environmental interactions and economic importance, such as protecting the environment, promoting soil health, and serving as a source of food, spices, and medicinal compounds.
