Cells
All cells, whether animal or plant, have three basic features - a cell membrane, cytoplasm, and a nucleus. Plant cells also contain additional structures that distinguish them from animal cells. The document provides an overview of the key components of plant cells and how to view them under a microscope.

Editor's Notes
- #5 Teacher notes Cell Worksheet 1 accompanies this section. This worksheet has been designed to be used alongside a practical that involves the students collecting, preparing and studying onion and cheek cells in the lab. However, it could be used alongside the flash activity on slide 22 if the pupils do not have the opportunity to carry out the practical themselves.
- #6 Photo credit: Herve Conge, ISM / Science Photo Library Cells Worksheet 2 accompanies this slide. This could be completed while the animation is playing or in a practical session in which the students use microscopes. Teacher notes Some microscopes do not have a built in lamp/illuminator so this part of the animation will not be relevant. In this case students should be advised that they need to place their microscopes in an area with good lighting in order to see the slide. There are several safety issues involved in using microscopes. For example, when moving the microscope students should make sure they always carry it with both hands. They should hold the arm with one hand and place the other hand under the base for support. It is important that students are careful when using the coarse focusing wheel – turning this too far can result in the objective lens hitting the slide or stage. This could cause breakages.
