Why are some cells binucleate?
Binucleate: Having two nuclei. Binucleate cells are due to a defect in cytokinesis, the process by which two daughter cells separate at the completion of cell division.
What do binucleate giant cells secrete?
Bovine binucleate trophoblast giant cells (BNCs) produce large amounts of PAS-positive cytoplasmic granules. After fusion of BNCs with uterine epithelial cells, the contents of these granules are released into the maternal stroma which underlies the uterine epithelium.
What is difference between binucleate and Dikaryotic?
The main difference between binucleate and dikaryotic is that binucleate is the containment of two nuclei, whereas dikaryotic is the presence of two genetically distinct nuclei inside the cell. Binucleate and dikaryotic are two nuclear features that occur in different cells.
Which one of the following is an example of Binucleated organism?
Examples of binucleated cells are: 1. Tapetal cells of microsporangium (tapetum is the innermost wall layer of microsporangium which develops further and becomes pollen sac). 2.
What cell has two nucleus?
Binucleated cells are cells that contain two nuclei. This type of cell is most commonly found in cancer cells and may arise from a variety of causes. Binucleation can be easily visualized through staining and microscopy.
What are Binucleate cells called?
Chondrocytes are binucleate cells that are present in the cartilage. Muscle cells are multinucleate which is known as a syncytium.
What is the function of syncytiotrophoblast?
The syncytiotrophoblast, the outermost layer of the human placenta, is the main site of exchange for drugs and metabolites, nutrients, waste products, and gases between the maternal and fetal circulations.
Why is it called syncytiotrophoblast?
Syncytiotrophoblast (from the Greek ‘syn’- “together”; ‘cytio’- “of cells”; ‘tropho’- “nutrition”; ‘blast’- “bud”) is the epithelial covering of the highly vascular embryonic placental villi, which invades the wall of the uterus to establish nutrient circulation between the embryo and the mother.
What is the meaning of Binucleate?
What cells in the human body are Multinucleated?
Liver cells, muscle fibers, and osteoclasts are all normal cells that often have more than one nucleus. Cancerous cells and those infected with viruses can also have multiple nuclei at times. In addition to human cells, certain types of fungi have multinucleated cells.
Can cells have 2 nucleus?
A binucleated cell has two nuclei. Binucleated cells are cells that contain two nuclei. This type of cell is most commonly found in cancer cells and may arise from a variety of causes. Binucleation can be easily visualized through staining and microscopy.
Which type of cell is the smallest?
The smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich. The longest cell is the nerve cell.
