what is the difference between somatic cells and germ cells?
535251
"Somatic cells" is a fairly general term which refers to essentially all the cells of the body except for the germ line; the germ line being the cells in the sexual organs that produce sperm and eggs.

Like all cells, somatic cells contain DNA arranged in chromosomes. If a somatic cell contains chromosomes arranged in pairs, it is called diploid and the organism is called a diploid organism. (The gametes of diploid organisms contain only single unpaired chromosomes and are called haploid.)

Body cells make up the body of the organism, while gametes are sex cells that could be either a sperm or an egg cell. What does homologous mean? It means that each of the 4 chromosomes from one parent has a corresponding chromosome from the other parent.

Somatic cells and gametes. -Each body cell contains a set of 46 chromosomes, which come in 23 pairs.

Meiosis I is a type of cell division unique to germ cells, while meiosis II is similar to mitosis. Meiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes.

The difference is that each species has its own set number of chromosomes. For instance, all human cells (except gametes) have 46 chromosomes.

Organisms that reproduce sexually produce sex cells, or gametes, that carry a single set of chromosomes, the haploid number for the species. In contrast, body, or somatic, cells are the regular cells that form the organism's tissues and organs.

Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Difference Between Human Sperm and Ovum. Sperm is the male gamete, produced in the testis of a male, while Ovum is the female gamete, produced in the ovary of a female. Ovum, also known as egg cell and is said to be the largest cell in the female body. On the contrary Sperm cells is the smallest cell in the male body.

Germ cells are cells that create reproductive cells called gametes. Germ cells are located only in the gonads and are called oogonia in females and spermatogonia in males. In females, they are found in the ovaries and in males, in the testes.

Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

Which choice best distinguishes between mitosis and meiosis? Mitosis produces sex cells that are genetically identical to the parent cell, whereas meiosis produces somatic cells that are genetically different from the parent cell.

Sperm is the microscopic male reproductive cell while semen refers to the seminal fluid that contains millions of sperms. ... Sperm is the genetic bearer and is haploid, while semen has no such characteristic other than nourishing the sperm cells and keeping them motile.

The major difference between meiosis II and mitosis is the ploidy of the starting cell. Meiosis II begins with two haploid cells, which have half the number of chromosomes as somatic cells. ... Mitosis begins with a diploid cell. It will divide into two sister cells, both of which are also diploid.
498705
All cells in a higher eukaryote (like us) are diploid EXCEPT...for the germ cells eggs and sperm. Germ cells have only half the number of chromosomes as a diploid cell one of each pair - and are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.

Somatic mutation, genetic alteration acquired by a cell that can be passed to the progeny of the mutated cell in the course of cell division. Somatic mutations differ from germ line mutations, which are inherited genetic alterations that occur in the germ cells (i.e., sperm and eggs).
1162528
The key difference between somatic cell and egg cell is that somatic cell is a diploid cell that has a total of 46 chromosomes while egg cell is a haploid cell that contains 23 chromosomes. ... Somatic cells are the biological cells that involve in the formation of the body of an organism.
