What are the four functions of roots ?​

Answer 1

The first root that comes from a plant is called the radicle. A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem.

Answer 2

Answer:

Most root performs a variety many important functions, including anchorage, production of hormones, and absorption.

Explanation:

Some other roots demonstrate specialized functions like nutrient storage, vegetative reproduction, modification into spines, and surviving extremely harsh conditions.

• Absorption of water- Root hairs present on the roots increase the surface area of the root system, creating an efficient system to fulfill the need for more water.
• Absorption of nutrients- Most plants absorb much of their phosphorus from the mycorrhizal fungi that form a substantial amount of network both in the soil and within the root cortex.
• Assisting in Nitrogen-fixation- Symbiotic relationship can be seen in a small number of plant species with nitrogen fixating prokaryotes like bacteria. The bacteria or cyanobacteria often live in root nodules, passing the nitrogen compounds to the plants and receiving carbohydrates and minerals.
• Production of Hormones- Roots produce hormones such as Auxin which are required to keep the plant healthy. Roots degenerate if there is an insufficient supply of local auxin.

• The adventitious root is a type of root that originate from an organ other than the roots or the embryo and are important in rhizomatous and stoloniferous plants. they can be seen on underground stems like rhizomes and tubers. It makes the plant vegetatively propagate from the stem or cuttings of a leaf.

• Prop root - It is a type of root that provides additional stabilization and transport for certain plants with narrow stems.
