NEET BIOLOGY

Detailed explanation-1: -When during the cell cycle its time for the bacteria to reproduce but the conditions aren’t favorable the amoeba develops a tough wall around it known as a cyst, encysted amoeba divides by multiple fission and produces multiple pseudopodiospores. This phenomenon is known as sporulation.

Detailed explanation-2: -Hint: Multiple fission occurs by the repeated division of the nucleus inside the cell. The nucleus of the parent cell divides and this process occurs in unfavorable conditions. The parent cell converts into a cyst which contains many small daughter cells.

Detailed explanation-3: -The process of cyst formation in autosomal dominant polycystic kidney disease. Each cyst is thought to initiate from a single cell, as the result of either a second somatic mutation or from a haploinsufficiency or threshold effect.

Detailed explanation-4: -Encystation is the formation of a three-layered hard crust or a cyst around an amoeba to protect itself from unfavourable conditions. It is usually seen in amoebas in defense to unfavourable conditions.

Detailed explanation-5: -Under unfavourable conditions, amoeba withdraws its pseudopodia and produces a cyst (encystation). By multiple fission many pseudopodia spores are formed. This phenomenon is called sporulation.
