👉 Autotropism is a term used in biology and developmental biology to describe organisms that grow or develop from their parent organism. It refers to the ability of an organism to grow, reproduce, and develop its own body parts within its own cells. This means that the organism itself grows and develops its own tissues and organs without needing external resources such as food or water. Autotropism is a fundamental characteristic of most living organisms, including plants, animals, and even certain bacteria.
