Define the given terms alongwith an example (a) Bilateral symmetry, (b) Coelom, (c) Triploblastic.
Answers
Explanation:
An example of bilateral symmetry. Description. Benefits. *Bilateral symmetry means that the body can be divided along a plane that divides the animal into left and right sides. *Humans, dogs, and even sharks can exhibit bilateral symmetry
Coelom Definition. The coelom is a body cavity found in metazoans (animals that develop from an embryo with three tissue layers: ectoderm, mesoderm, and endoderm). ... The mesodermal tissue also goes on to form the blood, bones, digestive tract, gonads, kidneys, and other organs.
Explanation:
: Bilateral symmetry is the symmetry in which an organism is exactly divided into right and left halves by a single line of symmetry. e.g. Butterfly. The organisms which exhibit this type of symmetry are called as bilaterally symmetrical organisms. Coelom is the body cavity filled with fluid that runs the complete length of vertebrates to divide the body of an organism into inner tube and outer tube.Coelom at embryonic stage, divides the mesoderm into two layers. Coelom helps in absorption of shocks. Coelom also helps the organisms to grow independently away from the body wall. Coelom in mammals is divided into peritoneal, pleural and pericardial cavities. Triploblastic organization is represented by embryos possessing three germinal layers namely external ectoderm, middle mesoderm and inner endoderm. e.g. Members of platyhelminthes representtriploblastic organization . Organs and organ systems of the individuals are derived from these three germinal layers.

a) body can be divided into 2 similar halves only by one plane that passes through the central median eg:human b) coelom or body cavity is clossed cavity whichcontains the various body organ in it in multicellular animala c)animals having 3 germ layer in the embryo-outer ectoderm,inner endoderm and middle mesoderm are called triploblastic animals
