Question

7 the table below lists specialized cells. cell specialization depends on where the cell is located as cells are layered after the blastocyst develops. specify the layer described in each column.
drag and drop the answers to the correct boxes.
mesoderm ectoderm endoderm

• neuron brain cells
• epidermal cells
• pigment cells

• bone tissue
• red blood cells
• facial muscles

• lung cells
• pancreatic cells
• thyroid cells

Explanation:

After the blastocyst develops, three germ - layers form: ectoderm, mesoderm, and endoderm. Ectoderm gives rise to the nervous system and epidermis (neuron brain cells, epidermal cells, pigment cells). Mesoderm forms connective tissues, muscles, and blood cells (bone tissue, red blood cells, facial muscles). Endoderm forms the lining of internal organs and glands (lung cells, pancreatic cells, thyroid cells).

Answer:

Ectoderm: Neuron brain cells, Epidermal cells, Pigment cells
Mesoderm: Bone tissue, Red blood cells, Facial muscles
Endoderm: Lung cells, Pancreatic cells, Thyroid cells
