From the following, identify the pair of organisms which reproduces by binary fission. ?

In asexual reproduction, a single individual is capable of producing offspring.
The offspring that are produced are not only identical to one another but the exact copies of their parents.
Clone is also used which describe morphologically and genetically similar individuals.
Asexual reproduction takes place by 5 different methods:
- Fission
- Budding
- Spore formation
- Regeneration
- Vegetative propagation

Explanation:

In binary fission, the parent organism splits to form two new organisms.
- It is an asexual method of reproduction.
When the simple animals like Amoeba and paramecium cells have reached their maximum size of the growth, then first the nucleus of the amoeba & paramecium lengthens and divides into 2 parts.
- After that their cytoplasm divides into 2 parts, one part around each nucleus.
- In this way, one parent of amoeba & paramecium divides, and two smaller new organisms (daughter cells)of amoeba & paramecium come into existence.
- Thus, amoeba & paramecium reproduce by binary fission by dividing into 2 parts.

Hydra and yeast reproduce by the process of budding is an asexual method of reproduction.
- In budding, a small part of the body of the parent organism grows out as a 'bud' which then detaches and becomes an organism.
Cockroach reproduces sexually which means cockroach relies on eggs from a female and sperm from a male.
- But female cockroaches can also reproduce through the process of parthenogenesis.
- Parthenogenesis is a form of asexual reproduction in which an egg can develop into an embryo without being fertilized by a sperm.
