question 11 of 25
what are sporophytes and gametophytes?
a. two different types of vascular systems
b. two different kinds of seeds
c. two different kingdoms in the domain eukarya
d. two different forms a plant can have

Explanation:

In plants, there is an alternation of generations. The sporophyte is the diploid (2n) generation that produces spores through meiosis. The gametophyte is the haploid (n) generation that produces gametes (sperm and eggs) through mitosis. So, sporophytes and gametophytes are two different forms (generations) that a plant can have during its life cycle.

• Option A: They are not vascular systems. Vascular systems (xylem and phloem) are for transport in plants.
• Option B: They are not types of seeds. Seeds are structures for plant reproduction in some plants.
• Option C: They are not kingdoms. Plants are in the kingdom Plantae (in domain Eukarya), and sporophytes and gametophytes are part of plant life - cycle forms within the plant kingdom.

Answer:

D. Two different forms a plant can have
