Of the following which one is not the characteristic of triploblasts?
Correct answer: A. All of them have blood vascular system
- A. All of them have blood vascular system
- B. They may be coelomate pseudocoelomate or acoelomate
- C. They are included in grade bilaterian
- D. All of them have digestive system
Explanation
Triploblasts possess ectoderm, mesoderm and endoderm, but not all have a blood vascular system because simple triploblastic animals can transport materials by diffusion. They may be acoelomates, pseudocoelomates or coelomates and generally have a digestive system, so students may incorrectly reject option d by overlooking simple or incomplete digestive systems.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
