Eukaryotes 1 of 17 What does animal cells and plant cells both contain? Nucleus 2 of 17 What is Nucleus? Contains genetic material 3 of 17 What are Eukaryotic cells? Cells that contain their genetic material enclosed in a nucleus 4 of 17 What are Bacteria? Prokaryotes 5 of 17 What are Prokaryote cells? When the genetic material is NOT enclosed in a nucleaus 6 of 17 What's smaller Eukaryotic cells or Prokaryote cells? Prokaryote cells are much smaller 7 of 17 What do Prokaryote cells consist of? A single loop of DNA 8 of 17 What is 1cm? 1 × 10 to the power of 2 metres 9 of 17 What does the word 'mirco' mean in Biology? 1 millionth (1/1, 000,000) 10 of 17 What is the symbol for micrometer μm 11 of 17 What does the word 'nano' mean in Biology? 1 billionth (1/1,000,000,000) of a metre 12 of 17 What does 1 order of a magnitude mean? 10× bigger 13 of 17 A fox is around 40cm long. A tick living on a fox is 0.4cm long. How many orders of magnitude is the fox longer than the tick? 40/0.4 = 100. There are two orders of magnitude so that means that it is 2 orders of magnitude 14 of 17 What happens in mitochondria? Where aerobic respiration takes place 15 of 17 What is it called when cells divide? Cell cycle 16 of 17 Describe the stages of cell divison called mitois 1. The DNA repelicates to form two copies of each chromosome 2. One set of chromosomes is pulled to the end of the cell. The nucleus also divides 17 of 17
