- Which of the following is correct regarding female gametophyte development in Angiosperms? The female gametophyte develops in the anther The female gametophyte develops in an ovule within an ovary A female gametophyte develops from all four megaspores produced via meiosis All cells of the female gametophyte are haploidarrow_forwardMost of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.arrow_forwardAngiosperms rely on a number of control pathways that govern when to produce reproductive structures. Briefly describe any one of these pathways, including the processes, structures and/or molecules involved.arrow_forward
- The three illustrations represent the three types of relationships between the haploid gametophyte and diploid sporophyte generations found among plants. Identify the types of plants and the characteristics that belong with each of the three types of relationships. Bryophyte Ferns Seed plants ferns and horsetails mosses, liverworts, and other bryophytes Ginko biloba, spruce trees, and other gymnosperms The gametophyte requires nourishment from the sporophyte in order to survive. The sporophyte and gametophyte generations grow independently and produce differently shaped plants. The sporophyte cannot survive without nourishment from the gametophyte.
