DENDROLOGY

Detailed explanation-1: -Seed cones of conifers are different from those of other seed plants in having what is known as a compound structure, consisting of an axis that bears modified leaves called bracts, each of which subtends a separate seed-bearing structure called an ovuliferous scale (Figures 5.19, 5.20).

Detailed explanation-2: -The cone (or pinecone) is the reproductive structure of all conifer plants.

Detailed explanation-3: -In most conifers, the male gametophyte consists of four cells contained within the pollen grain. Female reproductive structures: Ovules (megasporangia) are borne on ovule scales in female cones, except for yews that bear seeds individually.

Detailed explanation-4: -The word “conifers” means “bearing cones.” Conifers are plants that use cones to house their seeds. Conifers are woody plants and most of them are trees such as pine trees, firs, cypresses, junipers, cedars, and redwoods. Conifers reproduce using their cones. Some cones are male and some are female.
