Death means the body of the organisim stops functioning.But in organisms like amoeba the parental body divides and so there is no natural death

Wahid Khan answered Oct 29, 2019
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).

Ruby Singh answered Mar 18, 2020
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.

D

Kanika S answered Apr 08, 2020
Because when they attain maturity by growth they divide due to asexual reproduction like Binary Fission.
So they don't have to die.

Mohsin Patel answered Apr 05, 2020
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

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

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

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

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

Sakshi Kasture answered 1 week ago
Option d is correct bcoz amoeba like organisms reproduce asexually so their body is ditributed among the offsprings.

Akshay Hosamani answered 4 weeks ago
D)

Gopal Singh answered 4 weeks ago
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

Ayvid Shrivastav answered 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.

Bts My Life answered Mar 30, 2020
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.

Immortal

Nikhil Sulaniya answered 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 answered 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

Kakubal Suma answered 5 days ago
It's because even parental organisms also become the part of their offspring

Silent Action answered 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

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

Devender Bharat answered 4 weeks ago
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 answered 1 week ago
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.

Harsh Agarwal answered Nov 10, 2018
Why is binary fission wrong

Mohan Kalyan answered Mar 22, 2020
They reproduce by binary fission

Shreya Saini answered 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.

Neha Kadam answered Apr 25, 2020
Option d is right

Sharmistha Giri answered 4 weeks ago

Amrutha Menon answered 4 weeks ago
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 .

Hansa Kharwas answered 4 weeks ago
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

Afifa Aaliya answered Jan 04, 2020
" 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.

Gayatri Chouhan answered 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.

Geeta Rayate answered 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..

Adina Kausar answered 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...

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

Oyerinde Ibrahim answered 3 weeks ago
The answer is D.

Harinath Harish answered 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

Pallavi Maheshwari answered May 21, 2018
Because singled celled organisms r divide into two daughters cell therefore no natural death is occur

Anu Pathania answered 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 answered 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 answered 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

Ambareesh Rai answered 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

Awantika Gupta answered 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.

Sweta Sharma answered Feb 20, 2020
D is the right ans

Mir Saima answered 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

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

Aditya Bhushan answered 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.

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

Bhavya Arora answered Feb 15, 2020
Answer is D 

Manuvg Manuvg answered 4 weeks ago
Option D

Umesh Yadav answered 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.

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

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

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

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

Answer is B

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

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

Aishwarya Shree answered 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.

Rameshummadisingh Sudha answered Apr 15, 2020
Because they both are Parasites. these parasites reproduce by binary fission

Ismayil Sab Walikar answered Jan 10, 2020
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.

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

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

Supriya Yadav answered Mar 18, 2020
D is correct

Savitha Savi answered 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
