Question

Difference between regeneration reproduction and fragmentation reproduction

Answer 1

Answer:

Fragmentation is form of asexual reproduction (vegitative) where certain organisms propagate through breaking off their body in small fragments,while in Regeneration organisms like planaria regain their whole body with just small bolus of cell.

Explanation:

Main thing to think here is that fragmentation is intentional method to reproduce (propagate) but regeneration is more like regaining of what's lost,as in case of lizard's tail.

For more clear view think of yourself,whenever you met with unfortunate accident and some skin tissue is torn apart,and after some time that injured area heals out,is it reproduction mean or just regaining what was lost. Regeneration is just the same.

I hope it'll help.

Answer 2

Reproduction is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. There are two types of reproduction to learn in elementary grades, asexual and sexual reproduction. ... Some cells reproduce by unequal division of the cells, this is called budding.

In the reproductive process, a male sperm and a female egg provide the information required to produce another human being. Conception occurs when these cells join as the egg is fertilized. Pregnancy begins once the fertilized egg implants in the uterus.

It helps maintain positive genetic variation in a population. When out-competing rivals and attracting partners in the struggle to reproduce, an individual has to be good at most things, so sexual selection provides an important and effective filter to maintain and improve population genetic health.

The stages of fertilization can be divided into four processes:

• sperm preparation,
• sperm-egg recognition and binding,
• sperm-egg fusion and
• fusion of sperm and egg pronuclei and activation of the zygote.
