Can cells have more than one nucleus?
Multinucleate cells (multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. For example, slime molds have a vegetative, multinucleate life stage called a plasmodium.
Why would a cell have more than one nucleus?
One of the reasons for more than one nucleus per cell is that when cytokinesis does not follow karyokinesis (nuclear division). Also Check: Are Ribosomes In The Nucleus?
How many nucleus are there in a cell?
A cell normally contains only one nucleus. Under some conditions, however, the nucleus divides but the cytoplasm does not. This produces a multinucleate cell (syncytium) such as occurs in skeletal muscle fibres. Some cells—e.g., the human red blood cell—lose their nuclei upon maturation.
Do plant cells have more than one nucleus?
Generally there is only one nucleus per cell, but there are exceptions such as slime molds and the Siphonales group of algae.
Which cell has 2nd nucleus?
Binucleated cells
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.
Can an animal cell have more than one nucleus?
An animal cell with numerous nuclei is called as syncytial because it refers to multinucleate condition which means that the cell contains more than one nucleus per cell. In simple words, you can say multi nuclei with a common cytoplasm.
Which organism has more than one nucleus?
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.
What is a cell nucleus?
A nucleus is a membrane-bound organelle that contains the cell’s chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
Why does a Tapetum have more than one nucleus?
The innermost layer of microsporangium is known as tapetum. Cells of tapetum have dense cytoplasm and more than one nucleus. The binucleate(with two nucleus) or multinucleate(more than two nucleus) condition arises due to fusion of two uninucleate(one nucleus) cells of tapetum.
