| Question | Answer |
| LIST FOUR FEATURES THAT ANIMAL AND PLANT CELLS HAVE IN COMMON | Nucleus, cytoplasm, mitochondria and cell membrane |
| GIVE TWO SUB-CELLULAR STRUCTURES THAT ARE PRESENT IN PROKARYOTIC CALLS BUT NOT EUKARYOTIC CELLS | Chromosomal dna, plasmids |
| GIVE TWO SUBSTANCES THAT A PLANT TAKES IN VIA ITS ROOT HAIR CELLS | Water and mineral ions |
| WHAT IS RESPIRATION? | Transferring energy from the breakdown os glucose |
| HOW CAN YOU CALCULATE TE MAGNIFICATION OF AN IMAGE IF YOU DON'T KNOW WHICH LENSES WERE USED? | Magnification= image size divided by real size |
| WHAT IS A GENE? | A section of dNA that codes for a particular protein |
| TWO 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 |
| DESCRIBE HOW YOU COULD INVESTIGATE THE EFFECT OF CO2 CONCENTRATION ON THE RATE OF PHOTOSYNTHESIS | Moving a lamp closer or further away from a plant |
| NAME THE TYPE OF RESPIRATION THAT REQUIRES OXYGEN | Aerobic respiration |
| THE BASIC UNITS THAT LIPIDS ARE MADE FROM | Carbon, hydrogen and oxygen atoms |
| THE TYPE OF POLYMERS YOU GET WHEN YOU JOIN TOGETHER SIMPLE SUGARS | COMPLEX CARBOHYDRATES MADE OF MONOMERS (THE SIMPLE SUGARS) |
| DESCRIBE AN EXPERIMENT TO SHOW THAT CARBON DIOXIDE IS A PRODUCT OF RESPIRATION | hydrogen 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 |
| WHICH FORM OF RESPIRATION TRANSFERS MORE ENERGY PER GLUCOSE MOLECULE ? | ANAEROBIC RESPIARTION |
| AN EXAMPLE OF WHEN LACTIC ACID WOULD BE PRODUCED AS A PRODUCT OF RESPIRATION | in anaerobic respiration, lactic acid builds up in the muscles causing fatigue |
| IS RESPIRATION AN EXOTHERMIC REACTION OR AN ENDOTHERMIC REACTION | an exothermic reaction |
| IN WHAT PART OF A CELL ARE AMINO ACIDS JOINED TOGETHER TO FORM A PROTEIN | the cytoplasm |
| WHAT IS THE PROCESS OF MAKING MRNA FROM DNA CALLED | Protein synthesis |
| GIVE THE INITIALS OF THE FOUR BASES PRESENT IN DNA | A + T C + G |
| WHY 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 |
| HOW HAVE ELECTRON MICROSCOPES BEEN ABLE TO INCREASE OUR UNDERSTANDING OF SUB-CELLULAR STRUCTURES | They let us see really tiny things, e.g. plasmids or viruses |
| GIVE THREE FACTORS THAT CAN LIMIT THE RATE OF PHOTOSYNTHESIS | Not enough light, too little carbon, the temperature |
| WHAT IS A TRIPLET CODE? | When an amino acid is coded by a sequence of three bases in the gene |
| DESCRIBE THE STRUCTURE OF A NUCLEOTIDE? | A base attached to the sugar, to the phosphate group |
| IN WHAT PART OF THE CALL DOES PHOTOSYNTHESIS TAKE PLACE | INSIDE CHLOROPLASTS |
| WHAT CAN YOU CONCLUDE IF A TEST SAMPLE TURNS A BLACK-BLUE COLOUR WHEN IODINE SOLUTION IS ADDED? | Starch is present |
| TWO THINGS THAT YOU COULD MEASURE WHEN INVESTIGATING THE RATE OF AN ENZYME CONTROLLED REACTION | how fast the product appears and how fast a substrate disappears |
