Describe the behavior of brown bats
The true statement about the relationship between true moss sporophytes and gametophytes is: (d) Sporophytes are parasites of gametophytes.
Sporophyte is the part of the life cycle in plants where the plants are asexual and in diploid phase of their life. The plants produce spores during this stage. In vascular plants sporophyte is the dominant stage of life.
Parasites are the organisms that live inside or outside an organism and depend upon that organism for their food as well. Apart from extracting food, the parasites also provide some kind of harm to the host they live in. Sporophytes are called parasites because they directly developed from the fertilized egg in archegonia.
The given question is incomplete, the complete question is:
Considering that the mature sporophytes of true mosses get their nutrition from the gametophytes on which they grow, and considering these generations as individual plants, what is true of the relationship between true moss sporophytes and gametophytes?
a. Sporophytes are endosymbionts of gametophytes.
b. Sporophytes are mutualists of gametophytes.
c. Sporophytes are commensalist of gametophytes.
d. Sporophytes are parasites of gametophytes.

The correct answer is lamellae
Answer:
D) anatomical features
Explanation:
The molecular systematics uses the data on the molecular structures to establish evolutionary relationships between the organisms. Techniques of DNA, RNA, and amino acid sequencing are used to compare the macromolecules of organisms. These studies provide information about the degree of relatedness among organisms. The closely related species share a higher degree of similarities in the sequences of these macromolecules. However, this branch of science does not include information about the anatomical and structural features to establish evolutionary relationships.
