Assertion : Under unfavourable conditions Amoeba withdraws its pseudopodia and secretes 3-layered cyst around itself. Reason : Organisms having relatively simple oraganisation shift to sexual method of reproduction just before onset of adverse conditions.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Encystation is a phenomenon for survival of amoeba during unfavourable condition. Once favourable conditions return, the encysted amoeba divides by multiple fission(mode of asexual reproduction) and produces minute amoeba.

Which of the following is cultivated through vegetative propagation-
1 Potato and Sugarcane
2 Banana and Ginger
3 Dahlia and Rose
4 All
Explanation:
Food crops such as potato, sweet potato, sugarcane, pineapple, banana, onion, rose, dahlia, ginger, etc. are propagated vegetatively. Plants produced in this way have characteristics identical to the parent plants; this is the main and most important advantage of vegetative propagation.

Given are some figures: Agave , Potato and Onion. Which of these is an example of Bulbil and bulb respectively
In asexual reproduction, each form is similar in that one organism is able to create many more organisms without the need for a mate, but they differ in the mechanism by which they create those organisms. It is more common in lower animals.
