⭐️ 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 *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #Alevel #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IB #AP
