Question

Growth in plants and animals is a/an:

• A. reversible change
• B. irreversible change
• C. exothermic change
• D. endothermic change

Answer 1

The correct option is B

irreversible change

Explanation for correct option:-

Option (b)

• Growth is defined as an increase in size and mass that is both positive and irreversible over time.
• All living organisms demonstrate this. An increase in cell size or number causes it.
• Animals only display development for a short period of time, whereas plants grow continuously throughout their lives.

Explanation for incorrect option:-

Option (a) is not the correct answer as growth in plants and animals is an irreversible change as plants and animals are continuously taking foods from nature and those nutrients are incorporated into the body. So we can not get back that plant and animal again.

Option (c) is not the correct option as it is not an exothermic reaction, in exothermic reaction heat is released.

Option (d) is not the correct answer as in endothermic reaction heat is absorbed.

Therefore, Option (b) is correct, Growth in plants and animals is an irreversible change.
