Therefore, attempts are being made to create hybrids only consisting of male plants. They are created in ways such as the cultivation of anthers in vitro followed by dihaploidization with colchicine [56,57] and the self-pollination of andromonoecious plants. The cultivation of anthers leads ...
Plant reproduction is the process by which plants generate new individuals, or offspring. Reproduction is either sexual or asexual. Sexual reproduction is the formation of offspring by the fusion ofgametes. Asexual reproduction is the formation of offspring without the fusion of gametes. Sexual reprodu...
IV. Male gametes are produced in small number V. There is a significant reduction in the number of eggs produced VI. In seeded plants non-motile male gametes are carried to female gamete by pollen tubes View Solution Assertion : The distribution of bryophytes and pteridophytes is limited. ...
How is sexual reproduction in red algae oogamous when they have non-motile gametes? What are the differences between sexual and asexual reproduction? What is the role of asexual reproduction in spore producing plants (eg. bryophyte, fern, lycophyte)?

Vascular plants: The vascular system evolved to facilitate the movement of plants from water to land. To be considered a vascular plant, a plant must contain lignified tissues such as xylem for transporting water and nutrients throughout the...
Plants have the unique capability to form embryos from both gametes and somatic cells, with the latter process known as somatic embryogenesis. Somatic embryogenesis (SE) can be induced by exposing plant tissues to exogenous growth regulators or by the ec
Ploidy manipulation is effective in seedless loquat breeding, in which flesh color is a key agronomic and economic trait. Few techniques are currently available for detecting the genotypes of polyploids in plants, but this ability is essential for most g
higher quantities of offspring than sexual ones. In animals, where separate sexes are the rule (ie. male and female individuals), the cost of males is regarded as a major problem [3,4]. However, many groups of eukaryotes do not produce “males” – most land plants are hermaphrodites in...
Cross-contamination - plants bioengineered to produce pharmaceuticals (such as medicines) may contaminate food crops. Provisions have been introduced in the USA requiring substantial buffer zones, use of separate equipment and a rule that land used for such crops lie fallow for the next year. ...
