pollen grain
A pollen grain is a mature microspore that consists of two cells (generative cell and tube cell) enclosed within a protective wall. A microspore is a haploid cell produced in the sporangia of seed plants that eventually develops into a pollen grain through the process of microsporogenesis.
A microspore develops into a male gametophyte in plants, specifically within the context of seed plants and some gymnosperms. Upon undergoing mitosis, the microspore forms a pollen grain, which contains the male reproductive cells. This pollen grain can then be transferred to female structures for fertilization, ultimately leading to the development of seeds.
Microspore
in Selaginella sp a strobilus contains both megaspores and microspore but in Licopoium sp they are in seperate strobili OWTCA-kln.Sl

Each microspore can develop into a male gametophyte,or pollen grain
The megaspore mother cell undergoes meiosis to produce four haploid megaspores, while the microspore mother cell undergoes meiosis to produce four haploid microspores. This division results in the formation of haploid spores that will develop into gametophytes in plants.

Yes, angiosperms have two types of spores. They have both a male (microspore) and a female (megaspore).
A woodland is an area of trees that usually contains a mixture of species, with mature and young trees.
