question 4 of 10
what role do totipotent cells play in the development of an animal?
a. they can become any type of cell in the body or in the placenta or umbilical cord.
b. they work together to perform distinct functions in the animal.
c. they produce the three germ layers of an embryo.
d. they produce proteins for an organisms growth and survival.

Explanation:

Totipotent cells have the ability to differentiate into all cell types of the organism and extra - embryonic tissues like those in the placenta and umbilical cord. Option B is incorrect as they don't work together in that sense for distinct functions. Option C is wrong because they are not specifically for producing germ layers. Option D is inaccurate as their main role is not protein production for growth and survival.

Answer:

A. They can become any type of cell in the body or in the placenta or umbilical cord.
