Things to note about the formatting: Words in red are words where in the syllabus it says “define aerobic respiration as ...” so I copy pasted the definition, therefore you should probably memorise these definitions. Important vocabulary is normally in bold. I have put all the section and sub-section names in bold and underlined e.g. “1. Characteristics of living things” so that you can find the corresponding section in the syllabus easily. Any information marked with a * is not necessary, but can make other stuff make more sense, or I used it on diagrams where I couldn’t remove a label without ruining the diagram. As far as I can remember, I have written on top of a diagram if you have to know the diagram or the position of the labelled parts etc.
Section I: Characteristics and classification of living organisms 1. Characteristics of living organisms Movement: an action by an organism or part of an organism causing a change of position, place, or aspect Respiration: the chemical reactions that break down nutrient molecules in living cells to release energy Sensitivity: the ability to detect or sense changes in the environment (stimuli) and to make responses Growth: a permanent increase in size and dry mass by an increase in cell number or cell size or both Reproduction: the processes that make more of the same kind of organism Excretion: removal from organisms of toxic materials, the waste products of metabolism (chemical reactions in cells including respiration) and substances in excess of requirements Nutrition: taking in of nutrients which are organic substances and mineral ions, containing raw materials or energy for growth and tissue repair, absorbing and assimilating them 2. Classification and diversity of living organisms 2.1 Concept and use of a classificatory system binomial system: a system of naming species in which the scientific name of an organism is made up of two parts showing the genus (starting with a capitol letter) and species (starting...
