The blood is divided into three parts namely RBC, WBC and blood platelets. WBC is further classified as Neutrophils, Eosinophils, Basophils, Lymphocytes, and Monocytes based upon the function preformed by them. The functions performed by them are as follows:Neutrophils – They are involved in killing harmful bacteria. Eosinophils – They protect the body form parasitic infection. Basophils – It is involved in allergic response and reaction causes inflammation due to the interaction. Lymphocytes – It exerts against viral infection. Monocytes – It is involved in formation of macrophages.
organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.
organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.
cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)
filter feeding is observed in porifera members.
alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
