  • a)
    The word “blasted” derives its origin from the word blastula which means a hollow ball of cells formed during the early stage of embryo
  • b)
    If the number of cell layers in blastula is two in number, i.e. ectoderm and endoderm, then such organisms are considered to diploblastic
  • c)
    If the number of cell layers in blastula is three in number, i.e. ectoderm, mesoderm and endoderm, then such organisms are considered to triploblastic
  • d)
    In diploblastic organisms, mesoglea, a well differentiated substance, is present between endoderm and ectoderm
Correct answer is option 'D'. Can you explain this answer?

The word “blasted” derives its origin from the word blastula which means a hollow ball of cells formed during the early stage of embryo. If the number of cell layers in blastula is two in number, i.e. ectoderm and endoderm, then such organisms are considered to diploblastic. If the number of cell layers in blastula is three in number, i.e. ectoderm, mesoderm and endoderm, then such organisms are considered to triploblastic. In diploblastic organisms, mesoglea, an undifferentiated substance, is present between endoderm and ectoderm.

Explanation:

Incorrect Statement:

D) In diploblastic organisms, mesoglea, a well-differentiated substance, is present between endoderm and ectoderm
- The mesoglea is actually a non-cellular, gelatinous substance found in between the two cell layers (ectoderm and endoderm) in diploblastic organisms.
- Diploblastic organisms do not have a mesoderm layer, which is why the mesoglea serves as a structural support instead.
- The presence of mesoglea is a characteristic feature of diploblastic organisms, not triploblastic ones.
Therefore, the incorrect statement is option D.
