Question

define the terms and give one example of each ?bilateral symmetry, coclom ,triploblostic​

Answer 1

Answer:

1. Bilateral Symmetry - The property of being divisible into symmetrical halves on either side of a unique plane.Examples of animals that possess bilateral symmetry are: flatworms, common worms ("ribbon worms"), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates..

2. Coelom-  The principal body cavity in most animals, located between the intestinal canal and the body wall.An example of a Pseudocoelomate is the roundworm.

3. Triploblastic - It means having a body derived from three embryonic cell layers (ectoderm, mesoderm, and endoderm), as in all multicellular animals except sponges and coelenterates.

Explanation:

Answer 2

Answer:

Bilateral symmetry - when a body is divisible into two equal halves in only one plane that is mid sagittal plane , it is called bilateral symmetry.

triploblastic- animals having three germ layers in the embryo ie the outer ectoderm, the inner endoderm and third germinal layer which lies in between Ectodem and endoderm are called triploblastic.
