BiologyCell CycleGCSEEdexcel Created by: x.lily.revisionCreated on: 02-03-22 16:27 What does mitosis allow to occur? growth, repair, asexual reproduction 1 of 19 What is the first phase of the cell cycle? interphase 2 of 19 What occurs during interphase? Chromosome are replicated and sub-cellular structures form 3 of 19 What is the second phase of the cell cycle? Mitosis 4 of 19 What is the last stage of the cell cycle and what happens during it? Cytokinesis - cytoplasm and cell membranes divide to create two cells 5 of 19 What are the four stages of mitosis in order? Prophase, Metaphase, Anaphase, Telophase 6 of 19 What happens during prophase? Chromosomes condense/coil up tightly 7 of 19 What happens during metaphase? Chromosomes line up along the middle of the cell 8 of 19 What happens during anaphase? Chromosomes are pulled to opposite ends of the cell 9 of 19 What happens during telophase? Nucleus splits 10 of 19 What does mitosis produce? Two genetically identical diploid cells 11 of 19 What is cancer? a group of diseases, where changes in cells lead to uncontrolled growth and division of cells 12 of 19 What do malignant tumours do? invade neighbouring tissues and spread throughout the body in the blood, leading to the creation of more secondary tumours 13 of 19 What do benign tumours do? stay in a specific part of the body 14 of 19 What are the 3 zones in the root of a plant (from tip to base)? zone of cell division, zone of elongation, zone of differentiation 15 of 19 Why are plants always able to create new tissues? they keep their ability to differentiate 16 of 19 What is cell differentiation? a process where a cell gains new sub-cellular structures in order to perform a specific function. 17 of 19 What is a stem cell? an undifferentiated cell that has not yet specialised to perform a specific function 18 of 19 Where can stem cells NOT be found? brain 19 of 19
