Question 4 • TX-Biology B-CR

Which two statements correctly describe the life cycles of mosses and angiosperms?I. Both life cycles have protected seeds.II. Both life cycles involve meiosis.III. Moss fertilization occurs in the air; angiosperm fertilization occurs in a pool of water.IV. Mosses release haploid spores into the surrounding environment; angiosperms release haploid pollen grains into the surrounding environment.

Answer
A
I and III
B
I and IV
C
II and III
D
II and IV

Explanation

Both mosses and angiosperms undergo meiosis, which produces haploid cells, so statement II is correct. Mosses release haploid spores, while angiosperms release haploid pollen grains, making statement IV correct. Mosses do not have seeds, and moss fertilization generally requires water rather than occurring in air; angiosperm fertilization does not take place in a pool of water.
