It details the mechanisms and purposes of mitosis, including growth, repair, and replacement of cells, leading to the formation of two genetically identical daughter cells with the same number of chromosomes as the parent cell. Meiosis is explained as the specialized cell division for sexual reproduction, producing four genetically distinct haploid cells (gametes). The text further defines stem cells as undifferentiated cells capable of differentiating into various cell types, highlighting their sources from embryonic and adult tissues. Their significant medical potential for tissue regeneration is emphasized, alongside a strong recommendation for using autologous (own) stem cells to avoid rejection, donor dependency, tissue typing, and ethical concerns associated with embryonic stem cells. Cancer is identified as a consequence of uncontrolled mitosis. Key concepts such as genes, chromosomes, alleles, and ploidy (diploid and haploid) are introduced within the context of cell division.","Cell division and stem cells  \nInside the cell nucleus: Cell division – Mitosis  \nStem cells  \nStem cells are undifferentiated cells that can differentiate into any other type of cell. Sources of stem cells are:  \n• embryonic tissue  \n• adult stem cells that occur in some tissue.  \nStem cells can be used to replace damaged or diseased tissue and so have many medical applications.  \nIf possible, it is better to use your own stem cells for the following reasons:  \n• no rejection  \n• no need to find a donor  \n• no need for tissue typing  \n• avoids the use of embryonic stem cells which raises particular ethical issues.  \nMitosis is a type of cell division which organisms use for:  \n• growth  \n• repair of damaged cells  \n• replacement of old cells.  \nMitosis produces 2 daughter cells. Each daughter cell is:  \n• genetically identical  \n• has the same number of chromosomes as the mother cell.  \nMeiosis  \nMeiosis is the type of cell division which only occurs for:  \n• formation of sex cells(gametes) like eggs and sperm for sexual reproduction.  \nGenes code for characteristics.  \nChromosomes are linear  \narrangements of genes.  \nChromosomes come in pairs, one from each parent. So, genes come in pairs. An allele is a different version of the same gene. For example:  \nGene = eye colour Allele = brown, blue, green or hazel  \nMother cell has 4 chromosomes.(2 pairs)  \nDNA replicatesand one copy of each chromosome goes into each cell.  \nCancer is the result of uncontrolled mitosis.  \nMother cell has 4 chromosomes.(2 pairs-Diploid)  \nDNA replicates but the chromosome and its copy remain attached. One of each pair of chromosomes goes into a new cell.  \n• 4 new cells are formed. Each cell has half the chromosomes the mother cell has-they are  \nhaploid.  \nCells are not genetically identical to themother cell.  \n•  \n•  \nDivision 1  \nDivision 2","cbCaijUbLVilaFRA","https://ap.wps.com/l/cbCaijUbLVilaFRA","pdf",257804,1,"English","en",105,"# Cell division and stem cells\n## Inside the cell nucleus: Cell division – Mitosis\n## Stem cells\n## Mitosis\n## Meiosis","[{\"question\":\"What are the main purposes of mitosis in organisms?\",\"answer\":\"Mitosis is essential for organismal growth, the repair of damaged cells, and the replacement of old cells.
