Explains STEM cells, comparing human embryonic, adult stem cells, and plant meristems, including cloning potential, immune matching, infection risk, and ethical concerns. Connects stem-cell treatment possibilities with diabetes and paralysis. Summarises mitosis across six stages, the cell cycle link, and how mitosis supports growth, repair, and asexual reproduction, then links DNA change to cancer and uncontrolled division.","Edexcel GCSE Biology Cells and Control Part 1  \nCell differentiation  \nhow a cell changes and becomes specialised so that different cells can carry out different functions.  \nSTEM CELLS  \nUndifferentiated cell of an organism  \nDivides to form more cells of the same type, and can differentiate to form many other cell types.  \n\n| Human Embryonic stem cells | Can be cloned and made to differentiate into any cell type | Therapeutic cloning of stem cells to produce new tissue uses same genes so the body does not reject the tissue. Can be a risk of infection |\n| --- | --- | --- |\n| Adult stem cells | Can form into surrounding human cells e.g. blood cells | Tissue made from adult stem cells is matched to avoid rejection, risk of infection. Only a few types of cells can be formed. |\n| Meristems (plants) | Can differentiate into any plant cell type throughout the life of the pant. | Used to produce clones quickly and economically, e.g. rare species, crop plants with pest /disease resisitance |\n\nTreatment with stem cells may be able to help conditions such as diabetes and paralysis. Some people object to the use of  \nstem cells on ethical or religious grounds  \nMitosis occurs during growth, repair, replacement of cells. Asexual reproduction occurs by mitosis in both plants & simple animals producing genetically identical clones.  \n\n| Stage 1 | Interphase\u003Cbr>(not part\u003Cbr>of mitosis) | Before mitosis: Increase the number of sub-cellular structures e.g. ribosomes, mitochondria. DNA replication makes copies of chromosomes. |\n| --- | --- | --- |\n| Stage 2 | Prophase | Nucleus breaks down and spindle fibres appear. |\n| Stage 3 | Metaphase | Chromosomes are lined up on spindle fibres on the equator (middle) of the cell. |\n| Stage 4 | Anaphase | Chromosome copies are separated and pulled to opposite ends of the cell. |\n| Stage 5 | Telophase | A new nuclear membrane forms around each set of chromosomes. |\n| Stage 6 | Cytokinesis | Cell surface membrane forms to separate the cells (+new cell wall in plants) . |\n\nCell division and growth  \nMITOSIS is part of THE CELL CYCLE  \nMITOSIS produces two genetically identical DIPLOID CELLS  \nCancer  \nThe result of changes in DNA that lead to uncontrolled growth and division  \n| Growth in organisms | Growth in plants | Cell division and differentiation, elongation (cells increase in length) |\n| --- | --- | --- |\n|  | Growth in\u003Cbr>animals | Cell division and differentiation. |\n\nPercentile charts can be used to monitor growth  \nThe 50th percentile (bold line) is the median (average) growth of the population at that age. Half will be below and half above.  \nCells divide in a series of stages to produce two daughter cells, each with identical set of chromosomes to the parent cell (in the nucleus).  \nbetter hope – brighter future","cbCaioI64TFftfOb","https://ap.wps.com/l/cbCaioI64TFftfOb","pdf",802757,1,"English","en",105,"# Cell differentiation\n## STEM cells\n## Mitosis and the cell cycle\n## Cancer and cell growth\n## Percentile charts and growth monitoring","[{\"question\":\"How does cell differentiation relate to different cell functions?\",\"answer\":\"A cell changes and becomes specialised so that different cells can carry out different functions.
