Staying Alive
A Biology Unit for Year 11

The precise structure of the revised unit is not yet finalised. However, the specification statements which will be covered by the activities in this unit are shown below:

Staying Alive

2.1 (1) know differences between plant and animal cells using mesophyll cells and cheek cells as examples
2.1 (2) know that cell membranes are selectively permeable, allowing diffusion and osmosis [CC]
2.1 (3)n know that cell membranes are selectively permeable, allowing active transport [CC]
2.1 (6) know how cells, tissues, organs and organ systems are related to ensure the viable functioning of living organisms
2.2.1 (1) know the structure and function of the main organs of the digestive system (limited to stomach, pancreas, gall bladder, small and large intestine, rectum and anus)
2.2.1 (2) understand the role of enzymes in digestion (limited to amylase, protease and lipase)
2.2.1 (3) know the main changes to starch, protein and fats in the digestive system
2.2.1 (4)n understand the role of bile in emulsifying fats
2.2.1 (5) know tests to detect sugar, starch and proteins
2.2.2 (5) know that nutrients must be broken down into small, soluble molecules for absorption though the gut wall
2.2.2 (6) know that the waste products of respiration are removed from cells in the blood stream [SS]
2.2.4 (1) understand the difference between breathing and respiration [SS]
2.2.4 (2) understand that cellular respiration involves oxidation of food to release energy [SS]
2.2.4 (3) know the overall chemical equation for aerobic respiration of glucose [SS]
2.2.4 (4) know the role of mitochondria in respiration [SS]
2.2.4 (5) know the difference between aerobic and anaerobic respiration [SS]
2.2.4 (6)n understand the concept of 'oxygen debt' [SS]
2.3.1 (1) know that sunlight is the ultimate source of energy for the formation of all bio-mass [BA, ET]
2.3.1 (2) know the overall chemical change occurring in photosynthesis [BA, ET]
2.3.1 (3) know that the rate of photosynthesis may be affected by light intensity, carbon dioxide concentration or temperature [BA, WW]
2.3.1 (4) understand how these factors may limit the efficiency of photosynthesis [BA, WW]
2.3.1 (5) understand that the main product of photosynthesis (glucose) is stored as starch or used for growth and repair [BA, WW]


Specification statement codes in italic print indicate topics not included in single award science.
The square bullet (n) indicates statements that will only be assessed in the higher tier of the examinations.
