  2. Pollen - Wikipedia

    en.wikipedia.org/wiki/Pollen

    Pollen itself is not the male gamete. [4] It is a gametophyte, something that could be considered an entire organism, which then produces the male gamete.Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell.

  3. List of pollen sources - Wikipedia

    en.wikipedia.org/wiki/List_of_pollen_sources

    The worker bees in the colony mix dry pollen with nectar and/or honey with their enzymes, and naturally occurring yeast from the air. Workers then compact the pollen. storing each variety in an individual wax hexagonal cell , typically located within their bee brood nest. This creates a fermented pollen mix call beekeepers call 'bee bread'. Dry ...

  4. Tapetum (botany) - Wikipedia

    en.wikipedia.org/wiki/Tapetum_(botany)

    The tapetum is a specialised layer of nutritive cells found within the anther of flowering plants, located between the sporogenous tissue and the anther wall. Tapetum is important for the nutrition and development of pollen grains and a source of precursors for the pollen coat. [ 1 ]

  5. Pollen tube - Wikipedia

    en.wikipedia.org/wiki/Pollen_tube

    Pollen tube elongation is an integral stage in the plant life cycle. The pollen tube acts as a conduit to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.

  9. Floral morphology - Wikipedia

    en.wikipedia.org/wiki/Floral_morphology

    Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
