What is another name for microsporangium?
In seed plants, a spore-producing structure that produces microspores, which can grow to become the male gametopyte is known as microsporangium.
What is an example of a binucleate cell?
An example of a binucleate (containing two nuclei) cell is a cardiomyocyte, a muscle cell found in the heart. Cardiomyocytes can have two or more nuclei to support their large size and contractile function.
Were is pollen made?
Gymnosperms are heterosporous, producing microspores that develop into pollen grains and megaspores that are retained in an ovule. After fertilization (joining of the micro- and megaspore), the resulting embryo, along with other cells comprising the ovule, develops into a seed. The seed is a sporophyte resting stage.

What body surface are the fingernails located?
The fingernails are located on the tips of the fingers and toes, covering and protecting the nail bed.
What is plural of microsporangium?
microsporangia
What is another name for microsporangium?

The part of a flower that makes pollen called?
microsporangium
What is the name for the part of the plant where pollen is found?
It is the microsporangium of the anther lobe of a stamen.
Where would you find a microsporangium in the life cycle of a pine?
In the life cycle of a pine, a microsporangium is found within the male cones, also known as pollen cones. These structures produce microspores through meiosis, which later develop into pollen grains. The microsporangia are located in the scales of the male cones, where they facilitate the male gametophyte's development. This process is essential for the reproduction of pines, enabling fertilization with the female gametophyte produced in ovules.
What is other name of pollen sac?
microsporangium
How are the tapetal cell in microsporangium binucleate?
The tapetal cells in the microsporangium are binucleate because they contain two nuclei per cell. These nuclei are essential for the functions of the tapetal cells in nourishing and supporting the developing pollen grains. The presence of two nuclei allows for synchronized and coordinated activities within the tapetal cells during pollen development.
What cell does the gametophyte generation 1n begin in each pine cone?
In the female pine cone, the gametophyte generation (1N) begins in the megasporangium. For males, it begins in the microsporangium.
How does a sporangiophore function in the reproduction of fungi?
Microspores develop inside the microsporangium
Where are pollen grains transported from?
pollen grains are transported from the microsporangium (contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants)
What is the function of the pollen sacs in a flower?
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
What is an example of a binucleate cell?
An example of a binucleate (containing two nuclei) cell is a cardiomyocyte, a muscle cell found in the heart. Cardiomyocytes can have two or more nuclei to support their large size and contractile function.
