How tapetal cell could become bi nucleate?
Tapetal cells can become binucleate through a process called nuclear fusion, where two nuclei within the same cell merge to form a single cell with two nuclei. This can occur during specific developmental stages of pollen grain formation when the tapetum, which provides nutrients and support for developing pollen, undergoes certain stress or signaling changes that promote the fusion. Additionally, incomplete cytokinesis during cell division can also lead to binucleate tapetal cells, allowing them to maintain their function while adapting to the developmental requirements of the anther.
What is a binucleate?
A binucleation is a division of a nucleus without division of the cell's cytoplasm.
How tapetal cells could become bi-nucleate?
Tapetal cells can become bi-nucleate through mitosis followed by incomplete cytokinesis, leading to the formation of a cell with two nuclei. This can occur during the developmental process of tapetum formation in plants. The presence of two nuclei in a tapetal cell can contribute to its role in providing support and nourishment to developing pollen grains.
What is other name of pollen sac?
microsporangium
How does a sporangiophore function in the reproduction of fungi?
Microspores develop inside the 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.

How is the binucleate condition of liver cells explained?
The binucleate condition of liver cells is due to incomplete cytokinesis during cell division, resulting in the retention of two nuclei in a single cell. This allows for continued cell function and growth without the need for increased cell division. It is a unique adaptation that helps liver cells maintain their metabolic functions.
What is plural of microsporangium?
microsporangia
If a cell undergoes mitosis but not cytokinesis the product is?
The product would be a cell with two nuclei, resulting in a binucleated cell. This can often be found in certain cancer cells and is known as a bi/multinucleated cell.
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 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.
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.
What is an aeciospore?
An aeciospore is a binucleate spore of a rust fungus, formed in a chainlike series in an aecium.
