Answer:
a. Gametophytes of bryophytes
d. Sporophytes of seedless vascular plants
Explanation:
Bryophytes are non-vascular plants. The plant body is haploid gametophyte which is its dominant phase and bears sex organs. The gametophyte may be leafy as in moss and may be with thalloid as in liverworts.
Pteridophytes are seedless, true vascular plants. The plant body is the diploid sporophyte. The sporophyte is differentiated into true leaves, stem and roots.
Answer: Diversity, referring to the state of having many different organisms cohabitate within an area is a desirable outcome for many ecosystems. The presence of a wide spectrum of different organisms allows for more life to be able to thrive in an ecosystem. For example, an ecosystem with a wide array of shrubs, grasslands and forested areas is able to accommodate more life forms than an ecosystem of just forest. This increased capacity to support life directly improves the capacity of the biosphere to support life as well, diversity leading to growth.
