Why do organisms reproduce? A child may resemble a parent, but never look exactly the same. Reproduction is not growth-growth changes one individual; reproduction creates new individuals and keeps a species going across generations. When DNA copying passes information from parent to offspring, small copying differences create variation. Here is the key turn: reproduction is not just making more bodies; it keeps life continuing, while variation helps populations face changing conditions. In asexual reproduction, one parent produces offspring, usually similar. Fission, budding, fragmentation, regeneration, spore formation, and vegetative propagation are different routes to that same idea. In sexual reproduction, two parents provide male and female gametes. Their fusion makes a zygote, which develops into an embryo. At puberty, the body becomes capable of reproduction; reproductive health means accurate knowledge, hygiene, and respect. So, why reproduce? To continue the species-while variation gives life room to change and evolve.
