Detailed explanation-1: -In flowering plants, flowers are the structures used for reproduction. The pollen is considered as the male sex cells. The female part, i.e., the pistil, consists of the ovary, which produces female sex cells or eggs. Similarly, plants that do not bear flowers like conifers have male and female cones.

Detailed explanation-2: -The flowers are special structures for reproduction. They contain male parts that make pollen and female parts that contain ovules. Some plants have these male and female parts in different flowers.

Detailed explanation-3: -Conifers have cones (hence their name). Cones are the reproductive structures of the conifers: Cones are diploid tissue produced by the dominant sporophyte stage. The haploid gametophyte stage develops and produces gametes inside the cone.

Detailed explanation-4: -cone, also called strobilus, in botany, mass of scales or bracts, usually ovate in shape, containing the reproductive organs of certain nonflowering plants. The cone, a distinguishing feature of pines and other conifers, is also found on all gymnosperms, on some club mosses, and on horsetails.

Detailed explanation-5: -Gymnosperms produce two types of cones: pollen cones and seed cones. Pollen cones produce the male gametophytes, also called pollen grains. Seed cones produce female gametophytes and are generally larger than pollen cones.
