Q.1) Identify the characteristics of acoelomates.
A) Absence of mesoderm
B) Absence of brain
C) Coelom that is incompletely linked with mesoderm
D) Solid body without a cavity surrounding internal organs. ✅✅
Explanation:- Acoelomates do not possess a body cavity or coelom i.e the fluid-filled cavity between the digestive tract and the body wall that also surrounds the other internal organs is absent.
So, the correct option is 'a solid body without a cavity surrounding internal organs'.
The characteristics of acoelomates are a solid body without a cavity surrounding internal organs.
Explanation:
Acoelomates are invertebrates that have three germ layers that don't have a body cavity or a coelom. Acoelomate is the simplest form of an animal that contains 3 true tissues i.e. endoderm, mesoderm, and ectoderm. Acoelomates have a single aperture that serves as an inlet for food as well as an exit point for undigested waste.
For example- Tapeworms, Planaria, Liver fluke, etc.
