The gametophyte is a stage in the plants life cycle that undergoes alternation of generations.The primary job of gametophyte is Gamete production.
What are the male gametes in flowers? How is the genetic code analogous to the letters of the alphabet? What is missing from a cell during metaphase? What is the difference between kin selection and altruism? What is the difference between DNA and RNA?
What is the role of sex chromosomes in the development of male gametes and the occurrence of meiotic cell division in plants? Why is it so important for sex cells to undergo meiosis prior to fertilization? How does sexual reproduction by meiosis contribute to growth and/or survival of the org...
Consequently, the new plants develop directly from any of these parts without undergoing fertilization or union of male and female gametes. Other naturally formed plant organs which are considered vegetatively produced are likewise used. Vegetative propagation allows the production ofclonesor plants which...
What we have learned from transcript profile analyses of male and female gametes in flowering plants. Sci China Life Sci. 2010; 53 :927–933. doi: 10.1007/s11427-010-4033-1. [ Cross Ref ]Xin H, Sun M: What we have learned from transcript profile analyses of male and female gametes ...
Monoecy is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. ... Monoecy in angiosperms has been
1. Definition of Double Fertilization: Double fertilization is a unique reproductive process that occurs in flowering plants (angiosperms). It is characterized by the fusion of one female gamete with two male gametes. 2. Process of Double Fertilization: - During this process, one male gamete (spe...
It is a determinate, modified shoot having either or both a stamen and pistil where male and female sexual gametes are produced, respectively. It is the pistil that develops into a seed or seeds enclosed in fruits. In addition, this plant organ may also consist of outer whorls of petals an...
Antheridia is the male sex organ, and is a haploid structure whose function is to produce male gametes called antherozoids or sperms. Archegonia is the female sex organ, which produces female gametes mainly in cryptogams. It is responsible for the production of female gametes that are egg ...
Alternation of Generations In non-seed plants such as ferns, spores have hard outer coverings Spores are released into the environment where they can germinate into haploid gametophyte plants. These plants produce male and female gametes. After fertilization, a new sporophyte develops within a seed....
