An interactive, visual lesson exploring the structures and functions of animal and plant cells, designed for KS3 Science. Students investigate detailed cell models, select individual organelles and watch animations demonstrating their functions, including how water loss from the vacuole causes plants to wilt. The lesson includes interactive labelling, cell comparisons, animated microscope slide preparation, real microscope images, knowledge checks and application questions. It follows pages 9–13 of the Year 7 Cells booklet, allowing teachers to deliver the lesson without PowerPoint or students to work through the activities independently. simopsis
