In which of the following, growth is possible through increase in volume?
a)	Cartilage	b)	Striated muscle	c)	Never fiber	d)	Lens of eye

(a)

Growth occurs in body parts or cells through four different phages, as growth in cartilage occurs by secretion of extracellular matrix. Striated muscles grow through increase in volume. Nerve fibres grow by extension and growth of axons and dendrites, while lens of eye grow by multiplication of cells.
