Name the following and give one characteristic of each:
$(a)$ Living tissue that provides mechanical support in plants.
$(b)$ Highly specialised cells for being stimulated and then transmitting the stimulus very rapidly within the body of animals.
$(c)$ Animal tissue with elongated cells and contractile proteins responsible for movement.

(N/A) Collenchyma: It is a living mechanical tissue characterized by irregular thickenings of cellulose and pectin at the corners of the cells.
$(b)$ Nervous tissue (Neurons): These are highly specialized cells capable of receiving stimuli and transmitting impulses rapidly throughout the body.
$(c)$ Striated (Skeletal) muscles: These tissues consist of long,cylindrical,unbranched fibers that contain contractile proteins (actin and myosin) and exhibit characteristic light and dark bands (striations).
