Question

Tissue and organ formation begins during the process of organogenesis.

Which five of the following statements are true about organogenesis in a frog embryo?

1.The notochord forms from mesoderm and develops into the central nervous system.
2.The neural tube forms from ectoderm and develops into the central nervous system.
3.The endoderm gives rise to the lining of the frog's digestive tract.
4.The notochord does not persist in adult frogs.
5.The mesoderm gives rise to the epidermis of the frog's skin.
6.Somites form along the length of the notochord and neural tube.
7.Some somite cells migrate to other locations in the developing embryo

Answer 1

In frog embryo organogenesis, the neural tube forms from ectoderm to create the CNS, the endoderm forms the digestive tract lining, the notochord doesn't persist, somites form along the neural tube and notochord, and some somite cells migrate during development.

Step-by-step explanation:

Tissue and organ formation during the process of organogenesis in a frog embryo is a complex process involving differentiation from the three germ layers. The following five statements are true regarding this process:

• The neural tube forms from the ectoderm and develops into the central nervous system.
• The endoderm gives rise to the lining of the frog's digestive tract.
• The notochord does not persist in adult frogs; it plays a role during embryonic development.
• Somites form along the length of the notochord and neural tube and are critical in the development of various body structures.
• Some somite cells migrate to other locations in the developing embryo, contributing to the complexity and integration of body structures.

The incorrect statements from the given options are that the notochord forms the central nervous system (it does not; the neural tube does) and that the mesoderm gives rise to the epidermis of the frog's skin (the ectoderm gives rise to the epidermis).
