About Pinus- a gymnosperm:

• Pinus is a member of the Pinaceae family.
• Pine refers to any member of this genus of conifers.
• Most of them are trees, with a few bushes.
• They also have a longer lifespan compared to other plant varieties.
• Yellow pines, white pines, and lacebark pines are the three subspecies of the Pinus genus.
• Due to the monoecious nature of pines, both the female and male cones can be found on the same tree.

What materials go into making a pinus male cone?

• The apical bud, in the axil of a scale leaf, is where the male cones are carried in a cluster on a branch of unrestricted growth.
• A cone is made up of a central axis that is spirally covered with 60–135 microsporophylls.
