Anaerobic respiration in plant and yeast cells is represented by the equations anaerobic respiration in yeast cells is called fermentation and has economic importance in the manufacture of bread and alcoholic drink. Stem cells from adult bone marrow can form many types of cells including blood cells. Know that these factors interact and any one of them may be the factor that limits photosynthesis.

This allows sufficient transport of molecules into and out of the cell to meet the needs of the organism. Respiration in cells can take place aerobically (using oxygen) or anaerobically (without oxygen), to transfer energy. Fever, abdominal cramps, vomiting and diarrhoea are caused by the bacteria and the toxins they secrete.

You should be able to link the structure of a root hair cell to its function. Trilogy biology paper 1 1f  paper 1 (foundation) specimen mark scheme aqa gcse grade 9-1 combined science trilogy biology higher tier (ht) gcse comb. Revise the practical you did on the effect of a range of salt or sugar solutions on plant material you should understand that active transport moves substances from a more dilute solution to a more concentrated solution (against a concentration gradient, the opposite of osmosis).

Factors which affect the rate of transpiration are temperature, humidity, air flow and light intensity. Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells. Know that plants, to make proteins, also use nitrate ions that are absorbed from the soil.

You should be able to explain the use of antibiotics and other medicines in treating disease. Scientists have identified lifestyle risk factors for various types of cancer including smoking, obesity, common viruses and uv exposure. You should be able to describe cellular respiration as an exothermic reaction which is continuously occurring in living cells.

Inserted stents are used to keep the coronary arteries open. You should be able to describe the process of discovery and development of potential new medicines, including preclinical and clinical testing. Know that traditionally drugs were extracted from plants and microorganisms. Know that cells are the basic unit of all forms of life and you should know how structural differences between types of cells enables them to perform specific functions within the organism. They can be a causal mechanism has been proven for some risk factors, but not in others.

You should be able to describe cellular respiration as an exothermic reaction which is continuously occurring in living cells. Benign tumours are growths of abnormal cells which are contained in one area, usually within a membrane. In multicellular organisms the smaller surface area to volume ratio means surfaces and organ systems are specialised for exchanging materials. You need to know the details of all of the five aspects above, and they are all covered in more detail in the relevant specification section but are linked together here under the heading metabolism.
