Question

The peculiarities of some phylum are given below.Name the phylum(2)


a.Flame cell
b.Malphigian tubules c.Metameres
d.Spongin fibres​

Answer 1

Answer:

a. Flame cell - Platyhelminthes (primitive aquatic invertebrates)

b. Malpighian tubules - Arthropoda ( found in Cockroach)

c. Metameres - Annelida (earthworm show metameric segmentation)

d. Spongin fibers​- Porifera (sponge like irregular body)

Explanation:

A flame cell is a specialized excretory cell found in the simplest freshwater invertebrates, including flatworms, It controls their osmoregulation.

Malpighian tubule, in insects, any of the excretory organs that lie in the abdominal body cavity and empty into the junction between midgut and hindgut.

Metameric segmentation The repetition of organs and tissues at intervals along the body of an animal, thus dividing the body into a linear series of similar parts or segments (metameres). It is most strikingly seen in Annelida.

Spongin, a modified type of collagen protein, forms the fibrous skeleton of most organisms among the phylum Porifera, the sponges. It is secreted by sponge cells known as spongocytes. Spongin gives a sponge its flexibility.
