An organism is said dead when it's organs and total body stops to function. but in unicellular organism like amoeba the pariental body divides by binnary fission into its daughter cells. so there is no death for it.

There is no natural death in single celled organisms like Amoeba and bacteria because parental body is distributed among the offspring. In such organisms, reproduction occurs by ceil division where a cell (parent) divides into two halves and each rapidly grows into an adult (offspring).

Jyoti Rani

Because the parents body is divided into 2 daughter cells so the parent body converted to daughters cells hence there is no death in single cell organism

A single celled organism keeps on dividing into two by asexual reproduction. So at the end of their life cycle they simply divide and not die naturally. They only die because of external factors like high temperature and high pH.

Is used reproduce itself all the time by the binary fission so there is no natural death as its part are alive all the time when it has alredy reproduced itself

Death means stoppage of all functioning of body but in case of organisms like amoeba a parental cell is converted into daughter cell. parental cell divides in 2 parts by binary fission and in many parts by multiple fission during favorable conditions. some other examples: paramocium and euglena.

In prokaryotes like bacteria and some eukaryotes like amoeba, cell division is itself a mode of reproduction.
new organism form when parent body divide.
The most common mode in them is binary fission in which parent body is equally distributed into daughter organism .....

hence we say that there is no natural death in amoeba or bacteria

Kanika S

Because when they attain maturity by growth they divide due to asexual reproduction like Binary Fission.
So they don't have to die.

Sakshi Kasture
May 25, 2020
Option d is correct bcoz amoeba like organisms reproduce asexually so their body is ditributed among the offsprings.

Shoaib Ahmed
May 21, 2018
Becoz they do nt die...rather they divide into daughter cells(offsprings)

Aditya Kumar
Mar 13, 2020
D because the parental body goes asexual mode of reproduction (by binnary fission) and distributed among its offspring

Hansa Kharwas
May 09, 2020
There is no natural death in single celled organisms because they reproduce by division process and form daughter cell or new organism . the protoplasm (somatoplasm)of parent cell transfered into daughter or progeny cell

Arshiya Iqrar
Jan 06, 2020
There is no natural death in amoeba because of continous cell division throughout the life .

Adithya Shasan
Apr 04, 2020
Option D : The parental body is distributed among the offspring.

Ayvid Shrivastav
Mar 25, 2020
Correct option is D becoz in asexual reproduction offspring are morphological and genetically identical to their parents also referred as clone which make their identical copies so their death is immortal.

Gopal Singh

A single cell organism keeps dividing into two by asexual reproduction so at the end of there life cycle they simply divide not die naturally there death is only due to external factors like temperature and ph

Kakubal Suma
May 26, 2020
It's because even parental organisms also become the part of their offspring

Nikhil Sulaniya
Mar 25, 2020
Options d is correct because in amoeba the parental body is distributed among the offspring and the type of reproduction is asexual,so no natural death in amoeba. In amoeba they passes their functioning of body to their offspring

Theas Tv
Mar 29, 2020
A death is when all the organs and mechanisms stop which makes the whole body stop.... in humans plants death is described like that... but for single celled organism there is no death that exists.... an amoeba in favourable conditions divides its lf and becomes two and keeps on dividing like that ... when it divides it converts itself into two new offsprings

Option C is also right because when it reproduce by binary fission their body is distributed exactly half to the young individual. how can you say that option D is only right?

Dileep Ravula
Apr 24, 2020
There no natural death for bacteria and amoeba because they under go fission and distribute them to there daughter amoeba.

Silent Action
Jan 02, 2020
They are unicellular and cell division or rep. are same thing in them so they divide and form two or more doughter or proginies

Shreya Saini
Feb 25, 2020
Answer is D... because the parent body is divided into daughter nuclei by fission. so, the parent body doesn't exist...so no death occurs.

Devender Bharat
May 09, 2020
Answer is D due to a body is divided in to part and they service then उसके पीछे उसकी पीढ़ी का कोइ बचा ही नहीं then how become it will be dead

Ashok Dhaka
May 25, 2020
There is no natural death in single celled organism like amoeba and bacteria becoZ,,,. not exist there dead body... these organism reproduce by asexual reproduction , binary fission in which parental body divides into two daughters cells and it's dead body not exist so,we say no natural death in these organism.

Baby Shark
Jun 18, 2020
There is no natural death in single celled organisms like amoeba because at reproduction time their body is distributed into small parts (offspring)...which grow into mature parents and death is a situation of inactivity of body...where body can not do any function..

Yash Bhardwaj
Jun 08, 2020
There is no natural death in case of amoeba because amoeba divide into two daughter cell and lost its identity so option d should be correct however it divide by binary fission the result will be same in case of fregmention also in which the parent divide into daughter into daughter fragment and each fragment give rise to new one so answer d is correct ..

Mohan Kalyan

They reproduce by binary fission

Harsh Agarwal

Why is binary fission wrong

Amrutha Menon
May 08, 2020
Except single celled organism death is inevitable .Then why do single celled do not die .These organisms reproduce by binary fission which means their own body divides to form it's young ones & biological it doesn't die .

Afifa Aaliya

" D "
Because parental body distributed among the offsprings. In such organisms, reproduction occurs by the cell division. Where a cell divides into two halves and each rapidly grows into an adults.

Shah Farhat
Jun 08, 2020
When the single called organism grow, they undergo binary fission to form two daughters cells. Then there is no body part of the single called organism left to die. Therefore, they are regarded as immortal in biology

Geeta Rayate
Mar 30, 2020
The unicellular organisms divide and divide, for there existence and on earth..and the oldest cell can't be found because it has been divided into it's daughter cell ,and surviving in the form of daughter cells . so there I no natural death..

Gayatri Chouhan
Jan 03, 2020
Natural death means stop functioning like in human being not a single cell organism because the parental body undergoes cell division and divide itself into two daughters cells.

Mandeep Sharma
Apr 16, 2020
Because after division no parental part is left to divide

Adina Kausar
Feb 08, 2020
Parent body divides into draughts.. And again those draughts acts as parents individually and again divide into daughters... It continuously goes on and on.. So there is no natural death...

Harinath Harish
Jun 09, 2018
In humans if death is occur our body organs are stops suddenly but in ameoba the death is occur they producing as a offsprings

Because singled celled organisms r divide into two daughters cell therefore no natural death is occur

Anu Pathania
Apr 08, 2019
Amoeba undergoes binary fission and nothing left behind. however answer is D option how? please explain answer in contrast to C option

Kripal Deora
Feb 15, 2020
Because one parental cell divides into two cells and then they in four cells and it's go on that's the parental cell naturally never deaths.

Payal Kakade
Dec 24, 2019
Yes answer should be D only.

Explanation : During multiplication in unicellular organisms, the paren body wholly takes part in This process resulting in formation of offsprings or daughter cells.
hence there in no death because parents body becomes continuty of daughters life in Unicellular organisms.

Hope it helps ʘ‿ʘ

In single celled organisms reproduction is synonomous with growth.so they are immortal with parental body distribution among the offspring.

Awantika Gupta
Apr 08, 2020
They are immortal because there is no natural death occurs in them because their parental body divides into their respective daughters cell.

Ambareesh Rai
Jan 04, 2020
Because we cannot identify the parent cell from the 2 daughter cell after reroduction & parent cell also get divided into daughter which is itself capable to give birth to young offsprings

Mir Saima
Apr 15, 2020
There is no natural death in unicellular organisms as these organisms show asexual type of reproduction in which parental body itself gets divide and form the new organism of its species

Aditya Bhushan
Dec 24, 2019
D is correct.
when amoeba reproduce its primitive or parental species exist.
thats why their species is immortal as we study in NCERT.

Nidhi Yadav
Apr 15, 2020
D . unicellular organisms are immortal as parent exist as daughter

Sheetal Sharma
Jan 29, 2020
Correct answer is option 'D'

In the amoeba and bacteria there is no natural death because the parental body is distributed among the offsprigs, in such organisams like ameoba and bacteria reproduction occor by cell division into 2 halves and each grows into an adult offsprigs.

Umesh Yadav
Dec 27, 2019
In unicellular organisms like amoeba there is no difference between germ plasm and somatoplasm.
so the parents somatoplasm and germ plasm after reproduction will continue to live in the form of daughter.

Aman Singh
Feb 25, 2020
The parental body is distributed among the offspring.

Anita Bisht
Apr 08, 2019
In these organisms, the parent body undergoes cell division and itself divides into new daughter cells.

Shreya Mathpati
Nov 14, 2019
Since the parental body is distributed among offspring there is not occurring natural death hence they are immortal

Jeevesh Wadhwani
Jan 01, 2020
They perform binary fission and split into two daughter cells/clones

Preetam Karmod
Dec 26, 2019
D because of it divides into 2 parts by parent but they don't die

Sonal Nimbriya
Feb 19, 2020
Answer is D .
In amoeba there is no death because even after division the parent cell survive as its offspring .

Keerthi Priya
Feb 22, 2020
They are immortal because they don't end their lives but continue it on the form of their offsprings

Because they both are Parasites. these parasites reproduce by binary fission

Aishwarya Shree
Mar 14, 2020
The parental amoeba gets divided into 2 daughter cells by the process binary fission. so the parent no longer exists as parent but exists as offsprings. so this continues to the next generation also. so there is no death for such organisms.

Rohan Mahajan
Feb 15, 2020
The correct answer to the question is option D.

Sonal Mestry
Feb 22, 2020
Amoeba can do binary fission. their actual death means to stop the reproduction. therefore their natural death is not possible

Savitha Savi
Apr 06, 2020
In the single celled organisms , the offsprings are produced by the binary fission of the parental body ; wherein all the components of the patental body are divided and distributed to the daughter cells . So these single celled organisms are considered immortal
