Question

Match the reproductive system cell with its description or function.

Notochord	Formation of internal organs during development Germ layer that forms the lining of the digestive and respiratory systems Rod-shaped mesodermal structure that forms following gastrulation and releases signaling molecules Infolding of the blastula to form the three germinal tissue layers Hollow ball of cells that results from cleavage Rapid series of cell divisions without cell growth following fertilization A ball of mesoderm that eventually produces muscle and bone tissue The tube of ectoderm that gives rise to the central nervous system Germ layer that forms the circulatory and musculoskeletal systems The hollow cavity inside the blastocyst The site where the blastula folds inward; becomes the a-n-u-s in deuterostomes The initial diploid cell that results from fertilization Germ layer that forms the skin and nervous system The outer layer of the blastula which forms the placenta (in a placental mammal)

Answer 1

Organogenesis- Formation of internal organs during development.

Endoderm- Germ layer that forms the lining of the digestive and respiratory systems.

Notochord- Rod-shaped mesodermal structure that forms following gastrulation and releases signaling molecules.

Gastrulation- Infolding of the blastula to form the three germinal tissue layers.

Blastula- Hollow ball of cells that results from cleavage.

Cleavage - Rapid series of cell divisions without cell growth following fertilization.

Somite- A ball of mesoderm that eventually produces muscle and bone tissue .

Neural tube- The tube of ectoderm that gives rise to the central nervous system.

Mesoderm- Germ layer that forms the circulatory and musculoskeletal systems.

Blastcoel- The hollow cavity inside the blastocyst.

Blastopore- The site where the blastula folds inward; becomes the a-n-u-s in deuterostomes

Zygote- The initial diploid cell that results from fertilization.

Ectoderm- Germ layer that forms the skin and nervous system.

Trophoblast- The outer layer of the blastula which forms the placenta (in a placental mammal).
