Sporophytes (2n) undergo meiosis to produce spores that develop into gametophytes (1n) which undergo mitosis. Describe the role of the sporophyte and gametophyte in plant reproduction. The diploid stage of a plant (2n), the sporophyte, bears a sporangium, an organ that produces spores during meiosis.
In chemistry, a ketone (alkanone) /ËkiËtoÊn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond).etones differ from aldehydes in that the carbonyl group (CO) is bonded to two carbons within a carbon skeleton. In aldehydes, the carbonyl is bonded to one carbon and one hydrogen and are located at the ends of carbon chains.
Aldehydes and ketones have higher melting and boiling points than hydrocarbons of equivalent molecular weight. This is due to the attraction between molecule due to the polarity of the carbonyl group.ldol Condensation. The aldol condensation is a reaction in which aldehydes and ketones react to form larger molecules. A new carbon-carbon bond is formed. In this generalized reaction the a-carbon of one aldehyde forms a bond with the carbonyl carbon of the other aldehyde.
