Prokaryotic 7 of 30 Name the type of specialist cell found in the body which begins with an N nerve cell 8 of 30 where most of the chemical reactions in the cell take place mitochondria 9 of 30 the process by which a cell changes to become specialised for its job differentiation 10 of 30 image size / real size. is the ---- equation magnifcation 11 of 30 undifferentiated cells are called stem cells 12 of 30 mitosis results in the formation of 2 genetically --- cells identical 13 of 30 the ---- the surface area the faster the diffusion rate bigger 14 of 30 The net movement of water across a partially permeable membrane from an area of high concentration to an area of low concentration osmosis 15 of 30 Active transport requires energy from respiration 16 of 30 the spreading out of particles from an area of high concentration to an area of low concentration diffusion 17 of 30 thin membrane, large SA, lots of blood vessels and ventillation are all adaptations of exchange surfaces 18 of 30 When substances are absobed agaisnt a concentration gradient active transport 19 of 30 The cell used to fertilise the female egg sperm cell 20 of 30 Sperm cells have lots of mitochondria to give them energy 21 of 30 these cells have very few subcellular structures phloem cells 22 of 30 name the specialist cell that increases the surface area of the plants roots root hair cell 23 of 30 Name the structure that controls what goes in and out of the cell and holds it together cell membrane 24 of 30 The ribosomes are where --------- takes place protein synthesis 25 of 30 Which organisms have the most stem cells human embryos 26 of 30 how many cell divisions are there in mitosis one 27 of 30 single layer of surface cells and a good blood supply are adaptations of the small intestine 28 of 30 Stem cells can make ---- producing cells for diabetics insulin 29 of 30 gill filaments are covered in ----- which increases the surface area further lamellae 30 of 30
