The ultrastructure of cells (Edexcel SNAB)

This lesson bundle contains 7 lessons which have been designed to cover the Pearson Edexcel A-level Biology A (Salters Nuffield) specification points which focus on the structure of eukaryotic and prokaryotic cells and the functions of their components. The lesson PowerPoints are highly detailed, and along with the accompanying worksheets, they have been planned at length to contain a wide range of engaging tasks which cover the following A-level Biology content found in topics 2, 3 and 4 of the course:

2.2 (i): Know the structure and function of cell membranes
3.1: Know that all living organisms are made of cells, sharing some common features
3.2: Know the ultrastructure of eukaryotic cells, including nucleus, nucleolus, ribosomes, rough and smooth endoplasmic reticulum, mitochondria, centrioles, lysosomes, and Golgi apparatus
3.3: Understand the role of the rough endoplasmic reticulum (rER) and the Golgi apparatus in protein transport within cells, including their role in the formation of extracellular enzymes
3.4: Know the ultrastructure of prokaryotic cells, including cell wall, capsule, plasmid, flagellum, pili, ribosomes, mesosomes and circular DNA
3.6: Understand how mammalian gametes are specialised for their functions (including the acrosome in sperm and the zona pellucida in the egg)
3.13: Understand how the cells of multicellular organisms are organised into tissues, tissues into organs and organs into systems
4.7: Know the ultrastructure of plant cells (cell walls, chloroplasts, amyloplasts, vacuole, tonoplast, plasmodesmata, pits and middle lamella) and be able to compare it with animal cells.
