: In an [[Animal Cell|animal cell]] the '''cell membrane''' is the outer layer of the [[Cell (Biology)|cell]].: In a [[Plant Cell|plant cell]] the '''cell membrane''' is protected by a [[Cell Wall|cell wall]] on top of it.: The '''cell membrane''' only allows in certain [[molecule]]s. This is referred to as a [[Partially Permeable Membrane|partially permiable membrane]]. This means some [[molecule]]s, like [[water]], can diffuse in and out of the [[Cell (Biology)|cell]], however, some cannot pass into the [[Cell (Biology)|cell]].{| class="wikitable"|-|[[File:AnimalCellMembrane.png|center|200px]]|[[File:PlantCellMembrane.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |The '''cell membrane''' of an [[Animal Cell|animal cell]] is the outer layer.| style="height:20px; width:200px; text-align:center;" |The '''cell membrane''' of a [[Plant Cell|plant cell]] is protected by the [[Cell Wall|cell wall]].|} ==Key Stage 5=={{#ev:youtube|https://www.youtube.com/watch?v=nsklF1w4eok}} ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/0198359373/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359373&linkCode=as2&tag=nrjc-21&linkId=952a73bbb09d222ecc4b50d200679849 ''Cell membranes, pages 6-7, 20-21, GCSE Biology; Third Edition, Oxford University Press, AQA ''] ====OCR====:[https://www.amazon.co.uk/gp/product/1782945695/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945695&linkCode=as2&tag=nrjc-21&linkId=ceafcc80bcad6b6754ee97a0c7ceea53 ''Cell membranes, pages 11, 25, 26, Gateway GCSE Combined Science; The Revision Guide, CGP, OCR '']:[https://www.amazon.co.uk/gp/product/1782945660/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945660&linkCode=as2&tag=nrjc-21&linkId=83aa4500ad7759e7f401a1c5ba5df758 ''Cell membranes, pages 12, 30, 31, Gateway GCSE Biology; The Revision Guide, CGP, OCR '']
