Hello,
For 3 mark answers you can mention the following points given below :
- It is also known as metameric segmentation or true segmentation. Here the body is divided into a number of segments where external divisions correspond to internal divisions.Eg Annelida, Arthropoda and chordata.
- In pseudo metamerism or false segmentation the body is segmented only externally no internal segmentation is seen.Eg - Tapeworms
Do add the examples as they carry marks. Hope this helps.
