What is the difference between juvenile phase and reproductive phase? Pls ans in 5 points.
Answers
(i) Juvenile phase. All organisms have to reach a certain stage of growth and maturity in their life, before they can reproduce sexually. This period of growth is called juvenile phase or vegetative phase (term used in plants). (ii) Reproductive phase. Reproductive stage in plants is represented by appearance of flowers. In animals the end of juvenile phase is indicated by many of them showing morphological and physiological changes prior to active reproductive behaviour.
A juvenile is an individual who has not yet attained its adult appearance, sexual development or size. In such instances, juveniles during this transmutation are often referred to as sub adults. Humans, on attaining the adult platform, are fully developed and their advancement and growth stops.
Adolescence marks the incipience of the procreative aspect in boys and girls. The evolution of subsequent sexual component is the beginning of this stage. Once the reproductive system started producing gametes such as sperm in male and ovum in female, they are competent of reproducing.
