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.
How many nucleus can be in a cell?
A cell normally contains only one nucleus . Under some conditions, however, the nucleus divides but the cytoplasm does not.
Can cancer cells have more than one nucleus?
The nucleolus becomes increasingly enlarged and more irregular in cancer cells – cells can have multiple nucleoli within the nucleus .
Which cell has no nucleus?
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
Why are some cells multinucleated?
Because the muscle cell is so large, -from aprox insertion to origin-, it needs more myonuclei. In case of hypertrophy for instance the volume of the muscle cell can only enlarge when there are more nuclei. So it is multinucleated from functional and structural (very long) perspective.
Which cells have more than one nucleus examples?
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.
What 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.
Which cell has 2nd 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.
Can a cell be Anucleated?
Anucleated cells
An anucleated cell contains no nucleus and is, therefore, incapable of dividing to produce daughter cells. ... Anucleated cells can also arise from flawed cell division in which one daughter lacks a nucleus and the other has two nuclei.
How many nucleolus are in a human cell?
Although usually only one or two nucleoli can be seen, a diploid human cell has ten nucleolus organizer regions (NORs) and could have more nucleoli. Most often multiple NORs participate in each nucleolus.
Can cardiac muscle cells have two nuclei?
Human cardiac muscle cells are the most physically energetic cells in the body, and according to various researchers they contain two nuclei in 25–40% . ... We summed up and discussed about ten possible biological arguments why binucleation may be beneficial for cardiac muscle cells as well as for the whole myocardium.
Are cells without nucleus living?
Nucleus is the brain of the cell and controls most of its functions. Thus without a nucleus, an animal cell or eukaryotic cell will die . Without a nucleus, the cell will not know what to do and there would be no cell division. Protein synthesis would either cease or incorrect proteins would be formed.
Why do prokaryotes don't have a nucleus?
Prokaryotes do have their genomic DNA concentrated and localized to a small area within the cell (nucleoid region). So it's not entirely accurate to say that prokaryotes don't have a nucleus. ... The cell can release DNAses into the cytoplasm to degrade viral DNA , with reduced risk of degrading it's own DNA.
Why do Rbcs not have a nucleus?
The absence of a nucleus is an adaptation of the red blood cell for its role . It allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion.
What is shown in the image a cell with no nucleus is shown?
Answer: if the image has no nucleus shown then it's a prokaryotic cell .....
Do all cells have a nucleus?
Only the cells of advanced organisms, known as eukaryotes, have a nucleus. Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae. Simpler one-celled organisms (prokaryotes), like the bacteria and cyanobacteria, don't have a nucleus.
