Match the following terms with their definitions: protostomes deuterostomes diploblasts triploblasts mouth develops first anus develops first endoderm, mesoderm, ectoderm endoderm,... Match the following terms with their definitions: protostomes deuterostomes diploblasts triploblasts mouth develops first anus develops first endoderm, mesoderm, ectoderm endoderm, non-living layer, ectoderm
Understand the Problem
The question requires matching the terms related to animal development (protostomes, deuterostomes, diploblasts, triploblasts) with their correct definitions. This involves understanding the developmental processes and tissue layers in different animal groups.
Answer
* **Protostomes:** mouth develops first * **Deuterostomes:** anus develops first * **Diploblasts:** endoderm, non-living layer, ectoderm * **Triploblasts:** endoderm, mesoderm, ectoderm
Here are the matches:
- Protostomes: mouth develops first
- Deuterostomes: anus develops first
- Diploblasts: endoderm, non-living layer, ectoderm
- Triploblasts: endoderm, mesoderm, ectoderm
Answer for screen readers
Here are the matches:
- Protostomes: mouth develops first
- Deuterostomes: anus develops first
- Diploblasts: endoderm, non-living layer, ectoderm
- Triploblasts: endoderm, mesoderm, ectoderm
More Information
These terms are used to classify animals based on their embryological development. Diploblasts and triploblasts refer to the number of germ layers, while protostomes and deuterostomes refer to differences in early development.
Tips
A common mistake is confusing the layers present in diploblasts and triploblasts. Remember 'tri' means three, so triploblasts have three layers.
