Phosphorus is an essential nutrient for plant growth. It plays a crucial role in various processes, including energy storage (in the form of adenosine triphosphate or ATP), cell wall formation, and nucleic acid synthesis. Among the given options, phosphorus is directly involved in the development of seeds. Seeds contain the genetic material and nutrients required for the growth of a new plant when conditions are favorable. Phosphorus contributes to the formation and strengthening of the seed coat, as well as the storage of energy and nutrients for the germinating seedling.

Ethers and alcohols have the same molecular formula but differ in their functional groups, making them functional group isomers. This means that they have different chemical properties despite having the same number and type of atoms.

Cycloalkenes are cyclic hydrocarbons with one or more double bonds. The general formula CnH2n-2 represents the loss of two hydrogens from the saturated cycloalkane formula CnH2n, due to the presence of a double bond.
