    1) Which of the following is a major trend in land plant evolution over the past 200 million years? A) the trend toward smaller size B) the trend toward a gametophyte-dominated life cycle C) the trend toward a sporophyte-dominated life cycle D) the trend toward larger gametophytes
  • biology 2 chapter 30 Flashcards | Quizlet
    Study with Quizlet and memorize flashcards containing terms like 1) Which of the following is a major trend in land plant evolution?
  • Gametophyte - Wikipedia
    The gametophyte is the sexual phase in the life cycle of plants and algae It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote, which has a double set of chromosomes
  • Gametophyte | Definition Examples | Britannica
    Over the course of evolution, the gametophyte stage has become progressively reduced Thus, the gametophyte stage is dominant in the more primitive (nonvascular) plants (bryophytes), whereas the sporophyte is the dominant phase in the life cycle of higher (i e , vascular) plants
  • Alternation of generations - Wikipedia
    Land plants all have heteromorphic (anisomorphic) alternation of generations, in which the sporophyte and gametophyte are distinctly different All bryophytes, i e liverworts, mosses and hornworts, have the gametophyte generation as the most conspicuous
  • During the evolution of land plants, the gametophyte has become . . .
    During the evolution of land plants, the gametophyte generation has become progressively smaller, especially in vascular plants where the sporophyte generation is dominant This trend is observed as plants evolved from non-vascular to vascular forms, leading to a reduction in the size and prominence of the gametophyte stage
  • Solved: During the evolution of land plants, the gametophyte has . . .
    Explanation During the evolution of land plants, the gametophyte has become progressively smaller
  • During the evolution of seed plants, the size of the gametophyte has:
    During the evolution of seed plants, the size of the gametophyte has decreased significantly This trend is important to understand the life cycle of seed plants and how they’ve adapted to their environments
  • 1. 1. 4: Life Cycles - Biology LibreTexts
    In plants, there are two distinct generations that alternate: the gametophyte and the sporophyte generation The gametophyte begins as a single-celled spore that germinate into a multicellular life stage
  • Plant - Reproduction, Life Cycles, Pollination | Britannica
    In all land plants, the two alternating generations are morphologically dissimilar In all bryophytes, the gametophyte remains dominant, and the sporophyte is physiologically dependent on it
