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.
In an aldehyde, the carbonyl group is on the end of the molecule. In a ketone, the carbonyl group is somewhere in the middle of the molecule. Example structures of aldehydes and ketones are given below. Carboxylic acids contain the carboxyl functional group, shown below.Physical Properties Aldehydes and ketones are polar because they contain a carbonyl group (oxygen is very electronegative compared to carbon).arboxylic acids contain the carboxyl functional group, shown below.
