BOTANY

Detailed explanation-1: -The female and male inflorescence of the pine tree develop as cones on the sporophyte. The female cones (female strobili, singular strobilus) consist of megasporophylls that carry uncovered (Gymno = naked / exposed, hence Gymnosperms) ovules.

Detailed explanation-2: -The ovule of a female pine cone bears two eggs, an archegonium, gametophyte, and a nucellus. Before fertilization, the ovule undergoes many cellular divisions in preparation for the development of the zygote, most importantly, production of a haploid gametophyte generation.

Detailed explanation-3: -The female pinecone, or megastrobilus, produces the ovule, or unfertilized seed. Scales (modified leaves) on the female cone open to receive pollen, then close. Fertilization takes place late the following spring. Over a two to three year period after fertilization, the woody female pinecone develops.

Detailed explanation-4: -Pine cones are the woody fruiting body and reproductive organ of pine trees. Once pollinated, the tree’s female cones develop as the seeds mature and are usually conical or round shaped.

Detailed explanation-5: -Pine cones grow on pine trees. They are how pine trees reproduce, or, in other words, make more trees. Usually, male and female pine cones are born on the same tree. Typically, the male cones, which produce pollen, are located on the lower branches of the tree.
