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.
- The carbonyl group of aldehyde is bonded to a hydrogen from one end, but in ketone, the carbonyl group is bonded to carbon atoms from both sides. - Therefore, a ketone functional group is always seen in the middle of a molecule, and aldehyde group is always at a termini.ldehyde. Aldehydes have a carbonyl group. This carbonyl group is bonded to another carbon from one side, and from the other end, it is connected to hydrogen. Therefore, aldehydes can be characterized with the âCHO group, and following is the general formula of an aldehyde. The simplest aldehyde is formaldehyde.
