UPSSSC PET 2023 (29 Oct Shift 1)
Give name of the process in which tadpoles develop into young frogs.
Answer (Detailed Solution Below)View answer ▾Hide ▴
Answer: Option A — Metamorphosis
Detailed Solution
As a tadpole becomes a frog its gills turn into lungs, the tail is absorbed and legs grow; this major change of form is metamorphosis, controlled by the hormone thyroxine.
Fertilization is the union of egg and sperm and budding is asexual reproduction in organisms like Hydra, so option (A) is correct.

Reproduction in Plants & Animals — UPSSSC PET Preparation
This question tests your understanding of Reproduction in Plants & Animals, a key topic in the UPSSSC PET General Knowledge section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
This topic covers reproduction: asexual methods such as fission, budding, fragmentation and vegetative propagation, sexual reproduction in flowering plants including pollination and fertilisation, and the human reproductive system. Questions often ask which method of reproduction an organism uses (binary fission in amoeba and budding in yeast and hydra), which agent pollinates which flower, and what each part of a flower does. Know the difference between self-pollination and cross-pollination, and the role of the ovary and ovule in forming fruit and seed. Practise the reproduction questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
