Answer 1

The correct option is A Both assertion and reason are true and reason is the correct explanation of assertion.

Growth can be defined as a permanent or irreversible increase in dry weight, size, mass or volume of a cell, organ or organism.

In plants, growth continues throughout their lifetime as they have meristematic areas where cell division occurs.

In higher multicellular organisms, the overall developement from the birth of an organism to its death is constituted by both growth and the progressive development.

Usually all the cells are the descendents of a single zygotic cell which divides and redivides to produce various kinds of cells that differentiate and constitute the organism. Development does not halt post-birth. Development is observed throughout the healthy phase of an organism. Most organisms never stop to develop. For example, our skin cells are replaced on a daily basis and millions of cells are produced by our bone marrow periodically.
