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...
The gametophyte is a stage in the plants life cycle that undergoes alternation of generations.The primary job of gametophyte is Gamete production.
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 ...
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...
Encased within the ovary, awaiting fertilization. In flowering plants, ovules are enclosed in the ovary which becomes the fruit. 4 Ovum (cytology) The female gamete in animals; the egg cell. 2 Ovule (Zoology) A small or immature ovum. 1 Ovum The mature female gamete of an animal; an egg...
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...
What does propagation mean in plants? Plant propagation isthe process of creating new plants. There are two types of propagation: sexual and asexual. ... The resulting new plant is genetically identical its parent. Asexual propagation involves the vegetative parts of a plant: stems, roots, or ...
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....
