The tassels of a corn cob represent the male reproductive structure of the corn plant, which is analogous to the stamen in a flower. Specifically, the tassel contains the pollen-producing organs called anthers, which release pollen grains.

As an AI text-based model, I'm unable to directly draw diagrams. However, I can describe the cellular components of a mature microspore of an angiosperm for you:

1. Cell Wall: The outermost layer providing structural support.
2. Plasma Membrane: Surrounds the cytoplasm, controlling the movement of substances in and out of the cell.
3. Cytoplasm: Gel-like substance where organelles are suspended.
4. Nucleus: Contains genetic material (DNA) and controls cellular activities.
5. Mitochondria: Organelles responsible for energy production through cellular respiration.
6. Endoplasmic Reticulum (ER): Involved in protein synthesis and lipid metabolism.
7. Ribosomes: Synthesize proteins.
8. Golgi Apparatus: Modifies, sorts, and packages proteins and lipids for secretion or transport.
9. Vacuole: Membrane-bound organelle responsible for storage of various substances.
10. Microtubules and Microfilaments: Part of the cytoskeleton, providing structural support and facilitating cellular movements.
11. Pollen Grain: The mature microspore itself, containing the male gametophyte of the plant.

This description provides an overview of the cellular components you would find in a mature microspore of an angiosperm.

The filiform apparatus is a structure found in the mature embryo sac of angiosperms (flowering plants). Its primary function is to guide the pollen tube towards the embryo sac during fertilization. The filiform apparatus consists of several elongated cells with highly specialized wall structures located near the micropylar end of the embryo sac. These cells produce chemicals that attract and guide the pollen tube, facilitating the successful fertilization of the ovule.

To determine the number of male gametophytes produced by the Abilobed, dithecous anther with 100 microspore mother cells per microsporangium, we need to understand the process of microsporogenesis.

Microsporogenesis involves the formation of microspores from microspore mother cells (also known as pollen mother cells) within the microsporangium. Each microspore mother cell undergoes meiosis to produce four haploid microspores. Therefore, if there are 100 microspore mother cells per microsporangium, each microsporangium will produce 4 * 100 = 400 microspores.

Each microspore has the potential to develop into a male gametophyte (pollen grain). Hence, the number of male gametophytes produced by the anther would be the same as the number of microspores produced, which is 400.

Therefore, the Abilobed, dithecous anther can produce 400 male gametophytes.
