Question

What pattern is formed by sporophytes and gametophytes in plant evolution?​

Answer 1

In the evolution of plants, the sporophyte generation has become increasingly dominant over the gametophyte generation. In bryophytes, the sporophyte is called a sporogonium and is nutritionally dependent on its gametophyte.

Step-by-step explanation:

In the life cycle of plants, there are two alternating generations: the sporophyte and the gametophyte. The sporophyte generation produces spores, while the gametophyte generation produces gametes (sperm and eggs). Over time, the sporophyte generation has become more dominant in many plant groups. For example, in bryophytes (mosses and their relatives), the sporophyte is a small structure that grows on top of the larger gametophyte. The sporophyte is nutritionally dependent on the gametophyte and produces spores that will grow into new gametophytes.

Answer 2

Answer: Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis.

Explanation: This type of life cycle is called a haplodiplontic life cycle
