Fichas del conjunto (9)
- 1What are stem cells?Unspecialised cells with the ability to differentiate.
They are also able to divide to produce more undifferentiated stem cells (can renew themselves) - 2Complete the sentences: In animals, at the bone marrow, adult stem cells divide and ______________ to replace worn out blood cells - ___________ and __________.In animals, at the bone marrow, adult stem cells divide and DIFFERENTIATE to replace worn out blood cells - ERYTHROCYTES and NEUTROPHILS.
- 3Complete the sentences: In plants, stem cells are found in the ____________. In the root and stem, stem cells of the ____________ __________ divide and differentiate to become ________ vessels and phloem ________ _______.In plants, stem cells are found in the MERISTEM. In the root and stem, stem cells of the VASCULAR CAMBIUM divide and differentiate to become XYLEM vessels and phloem SIEVE TUBES.
- 4Why are stem cells important for medicine?Stem cells can develop into different specialised cell types, so they have a huge potential for use in medicine. Studying stem cells can help us to understand more about things like developmental disorders and cancer
- 5What is developmental biology?How organisms grow and develop
- 6How can stem cells be used in treating heart disease?Researchers are trying to make replacement heart cells to repair damaged tissue by using stem cells
- 7What is alzheimer's disease?A neurodegenerative disease whereby nerve cells in the brain die in increasing numbers, resulting in severe memory loss
- 8How can stem cells be used in treating alzheimer's disease?Researchers are hoping to use stem cells to regrow healthy nerve cells.
There is current research into using a type of stem cell called Induced Pluripotent Stem (iPS) cells. Scientists are developing a method for growing neurons from iPS cells to study the neurons similar to those affected by the disease in the brain - 9How can stem cells be used in treating Parkinson's disease?Patients suffer from uncontrollable tremors. It causes the loss of a particular type of nerve cell found in the brain which releases dopamine, which is needed to control movement. Transplanted stem cells may help to regenerate these cells
