Question

Difference between metameric and non metameric segmentation

Answer 1

Answer:

In some metameric animals the segmentation is visible externally but in others external segmentation has been lost and internal segmentation is best seen in the embryo. Non-Metameric Segmentation: ... Endoderm is not involved in metamery. Segmentation is not the same concept as metamerism

Answer 2

Difference between metameric and non metameric segmentation:

Metameric:

• The duplication of organs and tissues at particular periods along the body of an animal, which divides the body into a linear sequence of segments.

• It is mostly found  in Annelida.

• It is a type of body which exhibit by the member of annelida which means that the body contains the repeating segment which makes the whole. This segment is known as metamerism.

Non-metameric segmentation:

• In some metameric  the segmentation is appear externally but in  outside segmentation is lost and the inside segmentation is best seen in the embryo.

• It is mostly found inn tapeworm.

• While in Non-Metameric Segmentation, the segmentation is confined only to ectodermal derived tissue such as in the Cestoda tapeworms and others.
