Bryophytes alone have a relatively large ______ and an attached, dependent ______.a. sporophyte; gametophyteb. gametophyte; sporophyte

Key Concepts: Bryophytes, Sporophyte, Gametophyte Explanation: Bryophytes are plants that lack true roots, stems, and leaves. They have a simple thallus-like structure. They have a haplodiplontic life cycle, meaning they alternate between a haploid gametophyte and a diploid sporophyte generation, with the gametophyte generation being the dominant phase and the sporophyte generation being relatively small and dependent on the gametophyte for nutrition. Step by Step Solution: Step 1. Identify the two options: a. sporophyte; gametophyte b. gametophyte; sporophyte Step 2. Recall that bryophytes have a haplodiplontic life cycle where gametophyte is dominant Step 3. Recall that the other generation in haplodiplontic life cycle of bryophytes is small and dependent on the dominant gametophyte generation for nutrition Step 4. Choose the option where the large generation is dominant and the small is dependent on it, which is a. sporophyte; gametophyte Step 5. Therefore, the answer is 'a. sporophyte; gametophyte'. Final Answer: a. sporophyte; gametophyte
