noun

asexual stage in the life cycle of a plant (Botany)

Use "sporophyte|sporophytes" in a sentence

1. Sporophytes exist in the haploid, diploid and tetraploid phase.

2. The zygote grows into a sporophyte from within the Archegonium.

3. First, in all Bryophytes the ecologically persistent, photosynthetic phase of the life cycle is the haploid, gametophyte generation rather than the diploid sporophyte; Bryophyte sporophytes are very short-lived, are attached to and nutritionally dependent on their gametophytes and consist of only an unbranched stalk, or seta, and a single

4. Both the haploid and diploid sporophytes can propagate by means of zoids from plurilocular sporangia.

5. Certain motile cells of haploid plants may spontaneously give rise to diploid or tetraploid sporophytes which are homozygous.

6. The adult, or sporophyte, phase is the main phase of an Angiosperm’s life cycle

7. In mosses, liverworts and hornworts, an unbranched sporophyte produces a single sporangium, which may be quite complex morphologically.

8. The newly developed sporophytes also released this kind of biflagellate neutral zoospores to complete asexual reproduction.

9. The Antherozoid and egg fuse to form a diploid zygote, which functions as the mother cells of sporophyte generation

10. The Bryophyte life cycle consists of an alternation of generations between a haploid gametophyte generation and a diploid sporophyte generation

11. Bracken has typical fern reproduction, with the large sporophytes that reproduce asexually to produce the spores that disperse into new habitats

12. Ferns and lycophytes (pteridophytes) are free-sporing vascular plants that have a life cycle with free-living, independent gametophyte and sporophyte phases.

13. The strongest line of supporting evidence is that liverworts are the only living group of land plants that do not have stomata on the sporophyte generation.

14. Angiosperms are vascular plants, and all vascular plants have a life cycle in which the sporophyte phase (vegetative body) is the dominant phase and the gametophyte phase remains diminutive

15. Syntrichia laevipila is an acrocarpous (producing female structures and sporophytes at the tips of the main stems) moss that grows as small clumps on exposed tree bark.

16. The "Bryophytes" comprise three phyla of plants united by a similar haploid-dominant life cycle and unbranched sporophytes bearing one sporangium: the liverworts (Marchantiophyta), mosses (Bryophyta), and hornworts (Anthocerophyta)

17. The severity of acropetal scorching was found to be correlated with the concentration of fluoride in the bryophyte phyllid tissue, and in addition, samples high in fluoride had fewer sporophytes.

18. The "bryophytes" comprise three phyla of plants united by a similar haploid-dominant life cycle and unbranched sporophytes bearing one sporangium: the liverworts (Marchantiophyta), mosses (Bryophyta), and hornworts (Anthocerophyta)

19. Entosthodon fascicularis is a small, 2-4(-7) mm tall, acrocarpous (producing female structures and sporophytes at the tips of the main stems) species that grows in small patches on seasonally wet soil.

20. Apomixis, reproduction by special generative tissues without fertilization. It includes parthenogenesis in animals, in which the new individual develops from the unfertilized egg, and apogamy in certain plants, in which the generative tissue may be the sporophyte or the gametophyte

21. ‘An example of this is the Bryophyta, which includes liverworts, mosses and hornworts, but not the vascular plants.’ ‘In the ‘bryophytes’ (Hepaticophyta, Anthocerotophyta, and Bryophyta), the sporophyte plant remains small and dependent on the parent gametophyte for its entire life.’

22. Entosthodon rubiginosus is a small, 2-3(-5) mm tall, pale green to green acrocarpous (producing female structures and sporophytes at the tips of the main stems) moss that grows as individual stems or in tiny patches.

23. Scott (1911) supposed that the Bryophytes evolved by the degeneration of Pteri­dophytes on the basis of the similarity of the stomata in the land plants, in the sporophytes of Anthoceros and on the neck or the apophysis of mosses.

24. Pterygoneurum kozlovii is a short, 2-3 mm tall, acrocarpous (producing female structures and sporophytes at the tips of the main stems) moss that usually grows in small (less than 1 cm2) to medium sized (2-4 cm2) patches, sometimes forming rather widespread, yet intermittent turfs.

25. Slides of mature Archegone and antherids : note antheridia and archegonia are elevated on stalks above the thallus; on mature Archegone, look for sporophyte (2n) and egg (1n) in archegonia on antherids slide, look for sperm similar to moss Fig 19.3, 4 in lab manual preserved & live Marchantia look for female and male gametophytes, gemma cups
