- 1LIST FOUR FEATURES THAT ANIMAL AND PLANT CELLS HAVE IN COMMONNucleus, cytoplasm, mitochondria and cell membrane
- 2GIVE TWO SUB-CELLULAR STRUCTURES THAT ARE PRESENT IN PROKARYOTIC CALLS BUT NOT EUKARYOTIC CELLSChromosomal dna, plasmids
- 3GIVE TWO SUBSTANCES THAT A PLANT TAKES IN VIA ITS ROOT HAIR CELLSWater and mineral ions
- 4WHAT IS RESPIRATION?Transferring energy from the breakdown os glucose
- 5HOW CAN YOU CALCULATE TE MAGNIFICATION OF AN IMAGE IF YOU DON'T KNOW WHICH LENSES WERE USED?Magnification= image size divided by real size
- 6WHAT IS A GENE?A section of dNA that codes for a particular protein
- 7TWO VARIABLES THAT NEED CONTROLLING WHEN INVESTIGATING THE EFFECT OF PH ON AN ENZYME CONTROLLED REACTION?The product used and the size of the product pieces
- 8DESCRIBE HOW YOU COULD INVESTIGATE THE EFFECT OF CO2 CONCENTRATION ON THE RATE OF PHOTOSYNTHESISMoving a lamp closer or further away from a plant
- 9NAME THE TYPE OF RESPIRATION THAT REQUIRES OXYGENAerobic respiration
- 10THE BASIC UNITS THAT LIPIDS ARE MADE FROMCarbon, hydrogen and oxygen atoms
- 11THE TYPE OF POLYMERS YOU GET WHEN YOU JOIN TOGETHER SIMPLE SUGARSCOMPLEX CARBOHYDRATES MADE OF MONOMERS (THE SIMPLE SUGARS)
- 12DESCRIBE AN EXPERIMENT TO SHOW THAT CARBON DIOXIDE IS A PRODUCT OF RESPIRATIONhydrogen and carbonate indicator into 2 test tubes, place beans in each, seal tubes with a bung and leave them for set time- the hydrogen carbonate should have turned yellow
- 13WHICH FORM OF RESPIRATION TRANSFERS MORE ENERGY PER GLUCOSE MOLECULE ?ANAEROBIC RESPIARTION
- 14AN EXAMPLE OF WHEN LACTIC ACID WOULD BE PRODUCED AS A PRODUCT OF RESPIRATIONin anaerobic respiration, lactic acid builds up in the muscles causing fatigue
- 15IS RESPIRATION AN EXOTHERMIC REACTION OR AN ENDOTHERMIC REACTIONan exothermic reaction
- 16IN WHAT PART OF A CELL ARE AMINO ACIDS JOINED TOGETHER TO FORM A PROTEINthe cytoplasm
- 17WHAT IS THE PROCESS OF MAKING MRNA FROM DNA CALLEDProtein synthesis
- 18GIVE THE INITIALS OF THE FOUR BASES PRESENT IN DNAA + T
C + G - 19WHY IS IT IMPORTANT TO TAKE A THIN SLICE OF A SAMPLE BEFORE VIEWING IT UNDER A LIGHT MICROSCOPE?because it needs to let the light through it
- 20HOW HAVE ELECTRON MICROSCOPES BEEN ABLE TO INCREASE OUR UNDERSTANDING OF SUB-CELLULAR STRUCTURESThey let us see really tiny things, e.g. plasmids or viruses
- 21GIVE THREE FACTORS THAT CAN LIMIT THE RATE OF PHOTOSYNTHESISNot enough light, too little carbon, the temperature
- 22WHAT IS A TRIPLET CODE?When an amino acid is coded by a sequence of three bases in the gene
- 23DESCRIBE THE STRUCTURE OF A NUCLEOTIDE?A base attached to the sugar, to the phosphate group
- 24IN WHAT PART OF THE CALL DOES PHOTOSYNTHESIS TAKE PLACEINSIDE CHLOROPLASTS
- 25WHAT CAN YOU CONCLUDE IF A TEST SAMPLE TURNS A BLACK-BLUE COLOUR WHEN IODINE SOLUTION IS ADDED?Starch is present
- 26TWO THINGS THAT YOU COULD MEASURE WHEN INVESTIGATING THE RATE OF AN ENZYME CONTROLLED REACTIONhow fast the product appears and how fast a substrate disappears
