DENDROLOGY

Detailed explanation-1: -The reproductive structures in gymnosperms are called cones or strobili. The strobili bearing microsporophylls and microsporangia are called microsporangiate or male strobili. The cones bearing megasporophylls with ovules or megasporangia are called macrosporangiate or female strobili.

Detailed explanation-2: -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-3: -Most gymnosperms produce seeds in structures called cones or strobili (singular strobilus; Figure 8.1. 2). Cones evolved from modified leaves, and they can either be male cones that produce pollen, or female cones that produce ovules.
