Pine cone

A pine cone is a reproductive structure made of overlapping scales. Female cones bear ovules that develop into seeds, while male cones release pollen.

Ovule: A plant structure containing the female reproductive cell and developing into a seed after fertilization. Ovules sit on female cone scales and become seeds after fertilization.
Pine: A coniferous tree or shrub in the genus Pinus, with needle-like leaves and seed-bearing cones. Pine cones are the reproductive structures of trees in this genus.
Serotinous cone: A cone that retains seeds until heat or another environmental cue causes it to open. Some pines use cones that release seeds after fire or intense heat.
Pine nut: An edible seed harvested from several species of pine. Pine nuts are the seeds borne on the scales of certain pine cones.
Male cone: A pollen-producing cone that bears structures releasing pollen grains. Unlike seed-bearing female cones, male cones chiefly produce and shed pollen.
Pollen: A powdery mass of microscopic grains that carry the male reproductive cells of seed plants. Male pine cones release pollen that wind carries to female cones.
Conifer: A cone-bearing seed plant, usually evergreen, that produces seeds without enclosing them in fruit. Pines belong to this larger group of cone-bearing plants.
Lodgepole pine: A North American pine species whose cones can retain seeds and open in response to heat. Its serotinous cones are a well-known adaptation to fire-prone habitats.
Forest regeneration: The renewal of forest vegetation through natural processes or deliberate planting. Seeds released from cones can establish the next generation of pine trees.
Female cone: A seed-bearing cone whose scales carry ovules and later developing seeds. This is the cone type that forms the woody structure commonly called a pine cone.
