When comparing the mature seeds of a pine tree to an apple tree, which of the following is a correct statement?
A) The developmental sequences postfertilization are identical.
B) Both contain triploid tissue.
C) The nutritive tissues are both haploid.
D) Only the apple seed has a diploid seed coat.
E) Both contain haploid and diploid tissues.

Question

Quizplus · Accepted Answer

Pine trees and apple trees both contain haploid tissues such as the female and male gametophyte, and they also contain diploid tissues such as the seed coat and embryo. Thus, both contain haploid and diploid tissues, making option E the correct statement. However, the developmental sequences postfertilization are different between the two tree species, making option A incorrect. Option B is also incorrect since only the apple tree contains triploid tissue in the endosperm of the seed. Option C is incorrect as the nutritive tissues of a pine tree seed, the female gametophyte, and the seed coat are all diploid. Option D is also incorrect since both pine and apple seeds have a diploid seed coat.
