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.
37. Statements:(1) The simplest aldehyde is formaldehyde and the simplest ketone is acetone.(2) Carbonyl group polarity makes dipole-dipole interactions between like aldehyde molecules or like ketone molecules possible.(3) Reaction of a hemiacetal with an alcohol produces an acetal.ydrolysis of an acetal in an acid solution would yieldA) an aldehyde, a ketone, and one alcohol.B) an aldehyde, a ketone, and two alcohols.C) an aldehyde or a ketone and one alcohol.D) an aldehyde or a ketone and two alcohols.
