Question 2

Within the typical sexual reproduction of green algae,the genetic composition of the sporophyte form of the protist is

Accepted Answer

A)   None of the answer choices are correct.
B)   reproduced through mitosis, after the zygote single cell has formed.
C)   1n, or haploid, because the sporophyte follows meiosis.
D)   limited to the DNA found within the chloroplasts, because the sporophyte is a dormant form of the protist.
