In human case, 2n=46 chromosomes. 
23 Homologous pairs provided by the parental and maternal genetic information.
After mitosis, there are 2 new daughter cells, therefore they have the identical genetic information as the original cell. 
This means that the diploid number stays stable and the daughters can suffer mitosis again.

Smooth ER specializes in making lipids and steroids and it stores calcium in muscle cells. The rough ER has ribosomes attached to them which are in charge of making proteins. 

Muscle cells need a large amount of smooth ER for muscle contraction. Cells in the digestive tract need a large amount of rough ER because they are involved with the production and secretion of digestive enzymes (made of proteins) and mucus. ]]> 2016-08-26 02:41:37 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119966301 Enzymes https://padlet.com/ryk/fllv2rnl0jmf/wish/119966524 2016-08-26 02:44:17 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119966524 Hard at work on the cells topic padlet ryk https://padlet.com/ryk/fllv2rnl0jmf/wish/119966628 Well done]]> 2016-08-26 02:45:22 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119966628 Internationals are very excited about the library ryk https://padlet.com/ryk/fllv2rnl0jmf/wish/119966937 2016-08-26 02:46:39 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119966937 Enzymes  https://padlet.com/ryk/fllv2rnl0jmf/wish/119967055 2016-08-26 02:48:12 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119967055 https://padlet.com/ryk/fllv2rnl0jmf/wish/119967162 2016-08-26 02:49:21 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119967162 Example of primary active transport, where energy from hydrolysis of ATP is directly coupled to the movement of a specific substance across a membrane independent of any other species. https://padlet.com/ryk/fllv2rnl0jmf/wish/119967236 2016-08-26 02:50:15 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119967236 Mitosis https://padlet.com/ryk/fllv2rnl0jmf/wish/119967316 2016-08-26 02:51:17 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119967316 Meiosis  https://padlet.com/ryk/fllv2rnl0jmf/wish/119967934 2016-08-26 02:57:46 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119967934 Gene Mutations https://padlet.com/ryk/fllv2rnl0jmf/wish/119967949 2016-08-26 02:57:57 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119967949 Natural Selection https://padlet.com/ryk/fllv2rnl0jmf/wish/119968140 2016-08-26 03:00:54 UTC https://padlet.com/ryk/fllv2rnl0jmf/wish/119968140 Meiosis https://padlet.com/ryk/fllv2rnl0jmf/wish/119969145 Cell division happening in the gametic - germ cells of the body. Responsible for the production of gametes and, as a consequence, the reproduction process.
In mitosis, in human case,  a cell starts with 2n=46 (Diploid number of chromosomes). However, in the end there are four new cells with n=23 (Haploid number of chromosomes) and gamete cells, used for fertilization in order to get a fertilized egg. 
An interesting fact is that in Meiosis, there is actually Mitosis, know as Meiosis I.
