Diversity in Living Organisms
3,829 Questions
The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

A
Correct answer
Explanation
This is the correct option. Euspongia and Spongilla belong to the phylum Porifera. They reproduce sexually by formation of gametes and asexually by fragmentation.
-
They are radially symmetrical organisms with tissue level of organisation.
-
Their body bears four external rows of ciliated comb plates.
-
Digestion is both extracellular and intracellular.
-
Sexes are not separate in Ctenophores.
-
Reproduction is only by sexual means.
B
Correct answer
Explanation
This is the correct option as this is not a property of Ctenophores. Ctenophores' bodies bear eight external rows of ciliated comb plates that help in locomotion.
