What is a cell with one of each kind of chromosome?
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
What do you call a cell with two of each kind of chromosome?
A cell with two pairs of each set of chromosomes is called a [ diploid / haploid ] cell. These cells are typically found throughout the body tissues and are called [ germ / somatic ] cells.
What is the meaning of zygote?
zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.
What is metaphase?
Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. … There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
What is meant by a karyotype?
Karyotyping is a test to examine chromosomes in a sample of cells. This test can help identify genetic problems as the cause of a disorder or disease.
What is an example of a diploid cell?
Diploid cells, or somatic cells, contain two complete copies of each chromosome within the cell nucleus. The two copies of one chromosome pair up and are called homologous chromosomes. … Examples of diploid cells include skin cells and muscle cells.
What does a centrosome look like?
Centrosomes are made up of two, barrel-shaped clusters of microtubules called “centrioles” and a complex of proteins that help additional microtubules to form. This complex is also known as the microtubule-organizing center (MTOC), since it helps organize the spindle fibers during mitosis.
What is vegetative cell?
Any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes; somatic cells are produced from preexisting cells;.
