Cells - The Building Blocks of Life - GCSE Science

Here is a comprehensive overview of cell structure and function tailored for GCSE science revision. The video differentiates between the three major cell types—animal, plant, and bacterial cells—by detailing their sub-cellular components and explaining how each component’s structure relates to its specific purpose, such as the mitochondria providing energy for respiration and ribosomes facilitating protein synthesis. A key distinction is made between eukaryotic cells (plant and animal, which possess a nucleus) and prokaryotic cells (bacteria, which lack a nucleus). Furthermore, the texts examine specialized animal cells like sperm, egg, and ciliated epithelial cells, illustrating how their unique adaptations enable them to perform particular biological functions within an organism.
