Question

A researcher is culturing cells in a petri dish. After a few weeks, she notices that these cells have formed a "sheet," with junctions visible between individual cells. All of the statements are true regarding these cultured cells except:a. These cells have formed mesoglea.
b. These cells have formed an epithelium.
c. These cells have formed a structure similar to the epidermis or endodermis of jellyfish.
d. These cells may secrete enzymes or extracellular matrix proteins into their environment.
e. None of the answer options is false.

Answer 1

Answer:

a. These cells have formed mesoglea.

Explanation:

• Mesoglea is the amorphous, acellular layer in cnidarians that separates the ectodrerm and the endoderm.
• The mesoglea is referred to as the hydrostatic skeleton in cnidarians such as jelly fish.
• The mesoglea, although supplied with muscles and nerves, is completely composed of water.
