Question

If a heterotrophicunicellular organism like amoeba does not have consciousness andnervous system then how does it senses its food and what is the driving force and the secret behind the formation of pseudopodia in the absence of nervous system?? Explain

Answer 1

Amoeba do not have eyes, nose or other sensory organs to sense things in its environment. But they sense their environment through chemical attractions, a process known as chemotaxis. It can find its food by these chemical attractions. As soon as it encounters food near itself, it extends its pseudopodia and engulf the food.
