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?
The descriptive word “sexual” is attached to this type of propagation because the union of the male and female sexual gametes (the process is called fertilization) is a requisite in the production of the seed or in the development of a new plant from a spore. The certainty of sex in p...
The gametophyte is a stage in the plants life cycle that undergoes alternation of generations.The primary job of gametophyte is Gamete production.
Hint: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 e...
What is the name for a mature sexual reproductive cell? What is the male gametophyte of flowering plants called? What are the male and female reproductive cells called? What are male reproductive cells, or gametes, called? What is the name of the male reproductive structure in gymnosperm...
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...

“parents”. q2 define asexual reproduction. asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only. it does not involve the fusion of gametes. q3 what are the types of asexual reproduction? different types of ...
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
and together all stamens form the inner third whorl of a flower structure called theandroecium. Each stamen comprises a long tubular filament with a sac called theantherat the top.Pollengrains contain male reproductive cells or malegametesand are produced in anthers; each anther contains many ...
