Answer» Juvenile phase : The period of growth from birth till individual attains sexual maturity is called Juvenile phase. It is known as vegetative phase in plants. Reproductive phase : The period of growth after Juvenile or vegetative phase during which individual reaches sexual maturity and capable of producing gametes is called reproductive phase. In human beings reproductive phase begins on the onset of puberty usually after 13 or 14 years. In plants flowering marks the beginning of reproductive phase. Senescent phase: The phase begins after reproductive phase and marks the end of growth cycle in organisms
