What is an example of a multinucleate cell?

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. …

Which cells are Mononucleate?

Osteoblasts (mononucleate cells that are responsible for bone formation), from the margin of the defect that is being grafted, utilize the bone graft material as a framework, upon which to spread and generate new bone.

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.

Which organism has many nuclei?

Organisms that show multinucleate stage are fungi, e.g. coenocytic hyphae of Rhizopus, plasmodium of slime mould, skeletal muscle cells and osteoclasts in mammals are also multinucleate. Paramoecium (ciliated unicellular protozoan) contains one macronucleus and one or more micronucleus.

What is the only example of an Anucleate cell in the human body?

In particular, it refers to a cell that lacks a nucleus. For example, prokaryotic cells are anucleate. In addition, red blood cells (erythrocytes) are anucleate.

Are red blood cells multinucleated?

Interestingly, some cells in the body, such as muscle cells, contain more than one nucleus (Figure 3.20), which is known as multinucleated. Other cells, such as mammalian red blood cells (RBCs), do not contain nuclei at all.

What is Multinucleate?

Definition of multinucleated : having more than two nuclei a multinucleated macrophage multinucleated muscle fibers — compare binucleate, uninucleate.

Is Tapetum a binucleate?

Answer: Tapetal cells are very large cells with many nuclei. Tapetal cells undergo endomitosis where the nucleus in the nuclear membrane divides, but cytokinesis does not occur. Therefore they are bi/poly nucleate.

Which human body cells are Multinucleate?

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. as well.

Are red blood cells Anucleate?

RBCs are biconcave, anucleate discs 7-8µm in diameter (Fig 1). Their shape and the absence of a nucleus allow RBCs to be deformed to pass through capillaries (Fig 2).

Are red blood cells nucleated or Anucleate?

Nucleus. Red blood cells in mammals anucleate when mature, meaning that they lack a cell nucleus. In comparison, the red blood cells of other vertebrates have nuclei; the only known exceptions are salamanders of the genus Batrachoseps and fish of the genus Maurolicus.

What human cells are multinucleate?
