A-Level Biology - Prokaryotic Cells - Structure & Function (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. The basic characteristics of prokaryotic cells. Prokaryotes as unicellular organisms. Key differences compared to eukaryotic cells, such as size and the absence of a nucleus. 2. The detailed structure of prokaryotic cells. The functions of the cell wall (made of murein), cell-surface membrane, and ribosomes (70S). The nature of genetic material, including the circular chromosome and plasmids. 3. Additional features found in some prokaryotic cells. The role of the capsule for protection. The function of the flagellum for movement. The use of pili for attachment to surfaces. ** CHAPTERS ** 0:00 Introduction to Prokaryotic Cells 0:22 What Are Prokaryotic Cells? 0:58 Structure of a Prokaryotic Cell: Cell Wall and Membrane 1:13 Structure of a Prokaryotic Cell: Ribosomes 1:37 Genetic Material in Prokaryotes: Chromosome and Plasmids 1:59 Additional Prokaryotic Features: Capsule, Flagellum, and Pili ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #Alevel #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IB #AP
