About Life

Abstract

So far, we have touched on six of the traditional properties of living organisms: eating, breathing, excreting, moving, growing and reproducing. The only one that remains is “responding to outside influences”. A dog salivating at the smell of food, a flower opening in sunlight and a worm crawling towards moisture are examples of organisms responding to stimuli from their surroundings. All organisms respond to their surroundings in order to improve their chances of survival and reproduction.
