Monoceiousas male and female gametophyte are present on same plant💯💯💯💯💯😃😃😊😊👍👍👍👍👍

Answer

No it is a monocious plant contain both male ♀ cones 'learn only one thing MONO yane DONO means both gamete on same plant

Answer

No monoecious gametophyte

Answer

Introduction:
Pinus, commonly known as pine, is a genus of coniferous trees that belongs to the family Pinaceae. They are evergreen trees that have needle-like leaves and produce cones as their reproductive structures. Pinus is a heterosporous plant, which means it produces two types of spores that develop into male and female gametophytes.

Dioecious gametophyte in Pinus:
Pinus is unique among seed plants in that its male and female gametophytes are produced on separate trees, making it a dioecious plant. The male gametophyte develops within the pollen grain, while the female gametophyte develops within the ovule.

Male gametophyte in Pinus:
The male gametophyte in Pinus is produced within the pollen grain, which is produced by the male cones. The pollen grain contains two cells, the generative cell, and the tube cell. The generative cell divides to form two sperm cells. During pollination, the pollen grain is transported to the female cone, where it germinates to form the pollen tube. The pollen tube grows through the tissues of the cone to reach the female gametophyte.

Female gametophyte in Pinus:
The female gametophyte in Pinus is produced within the ovule, which is located on the female cone. Each ovule contains a megasporangium, which contains a single megaspore. The megaspore undergoes mitosis to form the female gametophyte, which consists of several cells. The female gametophyte contains one egg cell, several synergids, and antipodal cells.

Fertilization in Pinus:
Fertilization in Pinus occurs when the pollen tube reaches the female gametophyte. The two sperm cells are released from the pollen tube, and one of them fuses with the egg cell to form a zygote. The other sperm cell fuses with the two polar nuclei to form a triploid endosperm. The zygote develops into the embryo, which is contained within the seed.

Conclusion:
In summary, Pinus is a dioecious plant that produces separate male and female gametophytes. The male gametophyte is produced within the pollen grain, while the female gametophyte is produced within the ovule. Fertilization occurs when the pollen tube reaches the female gametophyte, resulting in the formation of a zygote and endosperm.

Sorry it's monoecious
