Give the functions of nerve cells and root hair cells.

Roots have numerous root hairs that increase the surface area for the absorption of water and minerals. These root hairs are in contact with the water present in the soil. Water enters the cells of the root hair by the process of osmosis. Osmosis is the movement of water from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Hence, they perform the function of absorption.

Plants have tube-like vessels to transport water and nutrients to other parts of the plant. These vessels are made up of special type of cells and are known as the vascular tissues. The vascular tissue that transports water and minerals in plants is known as the xylem. It forms a network of channels that connects the root to the stem and the leaves of the plant. Hence, water is transported to various plant parts.

first of all it is the question of biology

The function of root hairs is to collect water and dissolved minerals,As root hair cells do not carry out photosynthesis

Nerve cells produces all the proteins for the dendrites, axons and synaptic terminals and contains specialized organelles

Nerve cells perform the function of transmission of signals from Central nervous system to body and from body to central nervous system. So, to perform its function effectively the nerve cells have following features in their shape:

1) They are long cells. This helps then to transmit information quickly so that time is not wasted in passing information through a large number of cells.

2) Their long and slender shape helps in transmission to distant body parts.

3) They have multiple dendrites which help in connecting them to large number of cells and form a dense network.

The function of root hair cells are:

  • Allow more efficient water and nutrient uptake.
  • They function to increase the surface area of the root.
