Question

Answer

During unfavorable conditions amoeba reproduce by sporulation

Answer

Answer

Acc to options sporulation is correct answer over here.As far as unfavourable condition is said then obviously encystation occurs and is the accurate answer to this question.

Answer

Unfavorable condition me amoeba apne around ek hard covering bna leta b jiso hm encystation kehte h or favourable condition aane pe wo continuous divide krta h or bhut saare minute amoeba bna leta h jinko hm pseudospores bolte h or is phenomenon ko hm sporulation bolte h

Answer

Actually amoeba forms a cyst around itself in unfavourable condition. At that time amoeba divides by multiple fission . Later when the favourable condition returns the walls bursts out then the spores which are formed after multiple fission spreads out in the atmosphere. So technically it reproduces ( or divides as in unicellular organisms like amoeba this are similar ) by MULTIPLE FISSION. I can clearly confirm it is multiple fission you can check any websites. I don't know why so much answer is speaking it as sporulation it is the process by which they spread in atmosphere. Reproduction is by multiple fission.

Answer

A method known as multiple fission in adopted by the unicellular organisms amoeba to survive and reproduce under unfavorable conditions, when the condition are unfavorable amoeba withdraws it's psuedopodies and becomes almost round.

Answer

Sporulation..

Answer

In unfavourable conditions certain organism produce spore.This is a method of asexual reproduction which we already study in previous classes.

Answer

I verified your answer by many experts. None of the above is correct answer.In ream sense the amoeba (under unfavorable conditions) reproduce by Multiple fission. Under Multiple fission is does undergoes ENCYTATION. In Encytation amoeba withdraws its pseodopodia and forms a three layerd wall known as cyst wall.

Answer

During unfavorable conditions amoeba divides by sporulation but as it forms man daughter cells so it must considered as multiple fission.

Answer

A . multiple fission
during unfavourable condition , cell membrane disapper and cytoplasm spread around nucleus and form cyst. then a multiple daughter cell release by multiple fission .

Answer

B

Answer

During unfavourable conditions,amoeba actually reproduces by multiple fission not by sporulation....so option A is correct

Answer

C is correct answer
upvote me

Answer

Acc to question sporulation is correct

Answer

Correc t answer is option 'A'

Answer

A)  sporulation

Answer

Answer

Ya during unfavorable condition amoeba reproduced by sporulation.

Answer

Binary fusion

Answer

Correct answer is A

Answer

During unfavourable conditions like abundance of food ,the amoeba undergoes multiple fission where equational division forms amoebulae under encystment stage .The thick wall is later on bursted thereby giving rise to daughter amoeba.

Answer

Multiple Fission in Amoeba during Unfavourable Conditions

Multiple fission is the method of reproduction used by amoebas during unfavourable conditions. This process allows amoebas to survive in harsh environments by forming resistant structures called cysts.

Unfavourable Conditions

Unfavourable conditions for amoebas can include extreme temperatures, lack of food or water, or the presence of toxic substances in their environment. These conditions can threaten the survival of the amoeba, so they have evolved the ability to reproduce through multiple fission.

Process of Multiple Fission

1. Encystment: When amoebas detect unfavourable conditions, they begin the process of encystment. During encystment, the amoeba forms a protective cyst around itself. The cyst consists of a tough outer layer that shields the amoeba from the harsh environment.

2. Nuclear Division: Inside the cyst, the nucleus of the amoeba undergoes multiple divisions. This results in the formation of several daughter nuclei.

3. Cell Division: Each daughter nucleus then becomes surrounded by a portion of cytoplasm, forming individual amoebas. These daughter amoebas are called pseudopods.

4. Maturation: The pseudopods continue to develop and mature within the cyst.

5. Release: Once the unfavourable conditions improve, the cyst ruptures, and the mature pseudopods are released into the environment. These mature pseudopods can then grow and develop into fully functional amoebas.

Advantages of Multiple Fission

Multiple fission provides several advantages to amoebas during unfavourable conditions:

1. Survival: By encysting and forming resistant cysts, amoebas can survive in harsh environments where they would otherwise die.

2. Dispersal: The release of mature pseudopods allows amoebas to disperse and colonize new areas once the conditions improve.

3. Rapid Reproduction: Multiple fission allows amoebas to reproduce rapidly, increasing their population size and chances of survival.

4. Genetic Variation: Multiple fission can also result in genetic variation among the daughter amoebas, which may enhance their ability to adapt to changing environments.

Conclusion

During unfavourable conditions, amoebas employ multiple fission as a reproductive strategy to survive and ensure their continued existence. This process allows them to encyst, undergo nuclear and cell division, mature, and eventually release mature pseudopods, which can grow into functional amoebas. Multiple fission provides advantages such as survival, dispersal, rapid reproduction, and genetic variation, enabling amoebas to adapt to and thrive in challenging environments.

Answer

Bcoz they don't get sufficient food to survive and unfavorable conditions like surrounding climate. Hence the reproduction occurs in multiple fission

Answer

During unfavrable condition amoeba reproduce by sporulation..

Answer

During unfavorable it goes with sporulation

Answer

Multiple fission
