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.
INTRODUCTION O Carbonyl compounds have functional group called carbony C and there are two types of carbonyl compound that is aldehydes and ketones. Both aldehydes and ketones have general formula, CnH2nO O O General structure of aldehyde is R-C-H whereas ketone is R-C-R'.Aldehyedes are named by using the suffix-AL while for ketones, it was named by using the suffix-ONE. Carbonyl compounds can be prepared from the following reactions. 1. Oxidation of alcohol 2.oth aldehydes and ketones have general formula, CnH2nO O O General structure of aldehyde is R-C-H whereas ketone is R-C-R'.
