1. What is the function of the root hair , 2.What type of root system do monocot form?

Question

Biology

Answer 1

1) Root Hair Functions -- The ability of the root epidermis to absorb water from the surrounding soil is the same with or without root hairs, but the root hairs enlarge and extend the water absorbing surface.

2)Root system in Monocots-
A fibrous root system (sometimes also called adventitious root system) is the opposite of a tap root system. It is usually formed by thin, moderately branching roots growing from the stem.

A fibrous root system is universal in monocotyledonous plants and ferns, and is also common in dicotyledonous plants.

Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots. A typical mature tree 30-50 m tall has a root system that extends horizontally in all directions as far as the tree is tall or more, but well over 95% of the roots are in the top 50 cm depth of soil.

Answer 2

A root hair is what absorbs the water from the soil. It does this through osmosis. Monocots have fibrous root systems, meaning that the roots spread out instaid of having a single root with other "mini-roots" coming out of it (as in a taproot system).

Answer 3

T o absorbs water, monocot have fibrous root system.

Answer 4

root-hairs increase the surface area of the root thereby increasing contact with the soil to increase h2o absorption, mineral and other nutrient absorption. Monocots have fibrous root systems

Answer 5

monocots would have tap roots
