Question

'Metabolism and consciousness become defining property of living organism'. Justify with reason.

Answer 1

Consciousness is the state of being aware of surrounding. It is defined by the ability of the organism to respond to the stimulus which is known as irritability. If an organism is able to respond to stimuli, that means it is aware. As irritability is defining the property of life, so consciousness can be considered as defining property of a living organism.

Metabolism is the ability to split the complex substance (catabolism) and convert them into simpler ones which further forms energy (anabolism). The energy helps to carry several metabolic and physiological function which makes metabolism an important and defining property of life.
