FAQs on Body Cavity: Acoelomates & Coelomates Video Lecture - Biology for JAMB

1. What is the difference between acoelomates and coelomates?
Ans. Acoelomates are organisms that lack a body cavity, while coelomates have a true body cavity called a coelom. The coelom is a fluid-filled space that separates the body wall from the internal organs.
2. How do acoelomates and coelomates differ in terms of body structure?
Ans. Acoelomates have a solid body structure without any internal body cavity. Coelomates, on the other hand, have a body cavity called a coelom that allows for the development and movement of internal organs.
3. What are the advantages of having a body cavity in coelomates?
Ans. The body cavity in coelomates provides several advantages. It allows for the development and movement of internal organs, providing space for them to function properly. The coelom also acts as a cushioning and protective layer, reducing the risk of injury to the organs.
4. Can you provide examples of acoelomates and coelomates?
Ans. Acoelomates include flatworms, such as planarians, which have a solid body structure without a body cavity. Coelomates include various animal groups, such as mammals, birds, reptiles, and most invertebrates like annelids and arthropods.
5. How does the presence or absence of a body cavity affect the complexity of an organism?
Ans. The presence or absence of a body cavity can impact the complexity of an organism. Coelomates, with their well-developed body cavity, have a higher level of complexity as the coelom allows for the specialization and organization of organs. Acoelomates, lacking a body cavity, have a simpler body structure with less specialization in organ function.
