Mesoglea of Hydra is chemically:
1 Mucoprotein
2 Lipid
3 Protein
4 Mucopolysaccharide
Explanation:
D Mesoglea lies between the Epidermis and gastrodermis and is a jelly-like substance that are composed of small dense granules of glycogen which is a polysaccharide and mucoprotein. - Mesoglea serves as a skeleton to support the organisms and substratum for the cell attachment.

Main characteristics of Cnidaria is:
1 Diploblastic,radial symmetry and cnidoblast cells
2 Triploblastic, radial symmetry and cnidoblast cells
3 Diploblastic, bilateral symmetry and cnidoblast cells
4 Triploblastic, bilaterally symmetrical and cnidoblast cells
Explanation:
A Cnidarians appear to have diverse morphologies, but all members of this phylum universally possess stinging cells called Cnidoblasts. - These are multicellular, diploblastic animals with tissue level of organization. - There body is radially symmetrical.

Bud develops in an adult Hydra in
1
2
3 12days
4 2-4 days
Explanation:
D The bud enlarges, develops a mouth and circlet of tentacles at its free end. Once the bud is fully developed, it constricts as the base and finally separates the parent body to become individual organism. This process takes about 3 days to start and end.

Mesogloea is found in:
1 Amoeba
2 Sponges
3 Hydra
4 Earthworm
Explanation:
C Hydras are some of the simplest multicellular animals to have muscle. - The body wall consist of two layers of cells with a middle gelatinous layer called mesoglea. - In hydras and other two layered animals, one kind of cell serves as both muscle and epithelial cells.
