Stem cells

    Cards (19)

    • Meristems are plant tissue
    • Meristems are found in plant tissue of areas that are still growing
    • Meristems produce cells that can differentiate into any cell type
    • Meristems act like embryonic cells
    • Meristems can divide and differentiate into any cell type for aslong as it lives
    • Root hair cell has hairs to increase surface area of roots to absorb more water
    • Stem cells are found in early stage embryos and can differentiate into any cell
    • Stem cells are crucial for growth, repair and development in organisms
    • Adult stem cells are only found in certain places: bone marrow
    • Adult cells aren’t as versatile and can’t produce any type of cell, only certain ones
    • Stem cells can be used to make new blood cells or skin cells
    • Stem cells can be used in medicine to treat paralysis
    • Stem cells can be used in medicine to cure sickle cell ammonia with bone marrow transplant to produce red blood cells
    • Risks of stem cells: tumour development due to uncontrollable cell division
    • If transported stem cells are not grown using the patient, the body may recognise it as a a foreigner and trigger immune system to attack.
    • In stem cells, virus can live inside of stem cell and then infect patient to make them even more ill
    • People have ethical issues with stem cells and believe embryos shouldnt be used as it is a waste of a potential life.
    • a cell that is not already a specialised cell
    • a stemcell cannot change and then change again
