1.2 Relate structure to function in named specialised eukaryotic cells  
2      Describe the main features of eukaryotic membrane structure 2.1 Explain the importance of the major components of the fluid mosaic model of plasma membranes  
3      Demonstrate an understanding of how substances may enter and leave cells 3.1 Evaluate the importance of active and passive transport mechanisms

“There are some phrases that you may not be familiar with when answering TAQs or trying to match your answers with assessment criteria. Here are some helpful tips:
To compare Identify the similarities and differences between two or more phenomena. Say if any of the shared similarities or differences are more important than others. ‘Compare’ and ‘contrast’ will often feature together in an essay question.
To describe Give an account of the properties of something, its features or characteristics, or how it looks / smells so as to provide an accurate description of it.
To evaluate To review the information stressing advantages, disadvantages and limitations and then bring the information together in the form of a conclusion. Give evidence to support the views and/or statements.
To explain To say how and/or why something occurs and setting out its meaning in detail (with reasons) to make it more understandable. To give an example of what you mean, start with the topic and then give the ‘how’ or ‘why’.
To relate Show how things are connected, and how they possibly affect, cause, or resemble each other. “
