Answer 3

Organs Formed from the Endoderm

The endoderm is one of the three primary germ layers that form during embryonic development. It gives rise to various organs and tissues in the body. Let's examine the options provided and determine which organs are formed from the endoderm.

a) Nervous system, intestines, lungs: The nervous system, intestines, and lungs are not derived from the endoderm. The nervous system develops from the ectoderm, while the intestines and lungs are derived from the mesoderm and endoderm, respectively.

b) Notochord, liver, epithelial tissue of the intestine: The notochord, liver, and epithelial tissue of the intestine are all derived from the endoderm. The notochord is a rod-like structure that forms the basis of the vertebral column in vertebrate embryos. The liver and epithelial tissue of the intestine are also derived from the endoderm.

c) Skeleton, epithelial tissue, notochord: The skeleton and epithelial tissue are not formed from the endoderm. The skeleton develops from the mesoderm, while the epithelial tissue can be derived from various germ layers, including the ectoderm, mesoderm, and endoderm. The notochord, however, is derived from the endoderm.

d) Skeleton, sensory organs, nostrils: The skeleton and sensory organs are not formed from the endoderm. The skeleton develops from the mesoderm, while the sensory organs, such as the eyes and ears, are derived from the ectoderm. The nostrils are part of the respiratory system, which is derived from the endoderm.

e) Muscles, excretory organs, liver: The muscles and excretory organs are not derived from the endoderm. Muscles develop from the mesoderm, while excretory organs, such as the kidneys, are derived from the intermediate mesoderm. The liver, however, is formed from the endoderm.

Based on the information provided, the correct answer is b) notochord, liver, epithelial tissue of the intestine.
