Explain the mode reproduction used by ameoba and planaria
Answers
Answer:
By asexual method
Explanation:
The simple single celled organism amoeba and planaria reproduce asexually by fission. During this process the whole of the parent cell splits into two daughter cells which then grow individually.
heyyy mate......
Amoeba
It uses Binary fission to reproduce to give the birth to young ones.
Amoeba reproduces by a special mechanism known as binary fission. Meaning of binary fission is spliting into two. New organisms are rapidly produced by mitotic division. We can simply put it as one amoeba divides to become two. Nucleus and Cytoplasm are also divided in two. The division involves nuclear division (karyokinesis) followed by division of cytoplasm (cytokinesis). This takes place during favourable conditions.
Planaria
It uses fragmentation or regeneration to reproduce to give the birth to young ones.
If you cut one of these little flatworms, the two halves will grow into two new, whole organisms with the same genetic pattern. Pluripotent stem cells allow the planarians to regrow and replicate. These stem cells have the ability to generate any planarian tissue, a process, known as regeneration.
