BiologyIGCSECIE Created by: Emma VosCreated on: 05-05-13 15:44 Movement An action by an organsim causing a change in position or place 1 of 40 Respiration The chemical reaction that breaks down nutrient molecules to release energy 2 of 40 Sensitivity The ability to detect changes in the environment 3 of 40 Reproduction The process that make more of that same kind of organism 4 of 40 Excretion The removal of un-useful materials from an organism 5 of 40 Nutrition The taking in of nutrients 6 of 40 Binomial system A system naming species in which the scientific name of an organism is made up of 2 parts 7 of 40 How do we properly write "HOMO SAPIENS"? Homo sapiens 8 of 40 Vertebrates (MR FAB) Mammals, Reptiles, Fish, Amphibians and Birds 9 of 40 Example of a Ampthibian is..? Frog (They live on land and on water) 10 of 40 The 3 main kingdoms are: Animal, Plant and Fungi 11 of 40 Invertebrates Have no backbone (Arthropods, Annelids, Nematodes and Molluscs) 12 of 40 Types of Arthropods: CAMI- Crustaceans, Arachnids, Myriapods and Insects 13 of 40 Example Nematode Nematode 14 of 40 Example Annelid Earthworm 15 of 40 Feature of a Mollusc: Muscular foot e.g Snail 16 of 40 Types of flowering plants Monocotyledons and Dicotyledons 17 of 40 What is Mitochondria? An organelle where aerobic (with oxygen) respiration happens 18 of 40 What comes first in a PLANT cell the cell wall or the cell membrane? The cell wall 19 of 40 Chloroplast Only in plant cells and is used for light absorbtion 20 of 40 Function of the red blood cell: Transports oxygen 21 of 40 Function muscle cells: Contracts to get structures closer together 22 of 40 Function and adaptations of a Cilliated cell: Used to move mucus (snot like substance) they have tiny hairs called cillia which waft to move the mucus 23 of 40 Function and adaptations of a Root hair cell: Found in plant, they absorb minerals and water, they are elongated for more surface area 24 of 40 Function and adaptations of a xylem vessel: Transport water and support plant, no cytoplasm so water passes freely. 25 of 40 Function and adaptations of a pallisade cell: Carries out photosynthesis, many chloroplasts 26 of 40 What is an organelle A specialisized cell that has its own function 27 of 40 How do you calculate magnification? size of drawing/ size of specimen 28 of 40 Active transport Movement of ions in or out of a cell, against the concentration gradient using energy released during respiration 29 of 40 Osmosis The diffusion of water molecules from a region of high to low concentration through a semi-permeable membrane 30 of 40 Isotonic solution Concentrations are the same, no change in size 31 of 40 Hypertonic solution Concentration is greater in the cell so the cell shrinks 32 of 40 Hypotonic solution Concentration is greater outside the cell so the cell swells 33 of 40 Catalyst A substance that speeds up a chemical reaction 34 of 40 Enzyme Proteins that function as biological cataylsts 35 of 40 Substrate The molecules before they are made to react 36 of 40 Product The molecules that are made in a reaction 37 of 40 Catabolic reaction Molecules are broken down (e.g Digestion) 38 of 40 Anabolic reaction Molecules are combined (e.g turing glucose into starch for plant storage) 39 of 40 Biological washing powders Enzymes are added and help remove stains for example lipase- for fatty acids 40 of 40
