how does the root hair cell and nerve cell are modified to perform specific functions
Answers
Answer:
Nerve Cell
Transmit electrical nerve impulses and so carry information from one part of the body to another ie from receptor to an effector. Specialised Feature: Dendrites extend from the cell body to make connections with other neurones. Have a long axon (nerve fibre) to carry the impulse to the target organ.
Answer:
A root hair[1], or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope. They are found only in the region of maturation of the root. Just prior to, and during, root hair cell development, there is elevated phosphorylase activity. Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. Another adaptation that they have is root hair cells have a large permanent vacuole.
