By the end you’ll be able to

describe and compare the ultrastructure of animal, plant, fungal and protoctist eukaryotic cells, including the nucleus, nucleolus, nuclear envelope, rough and smooth endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, lysosomes, vesicles, vacuoles, chloroplasts, centrioles and cell-surface membrane
explain the functions of major organelles and relate structural specialisation to their roles in synthesis, transport, secretion, intracellular digestion, photosynthesis and aerobic respiration

compare prokaryotic cells with eukaryotic cells, including the presence of a cell wall, capsule, slime layer, plasma membrane, circular naked DNA, plasmids, 70S ribosomes, mesosomes or membrane infoldings in some specifications, and flagella

interpret electron micrographs and other images to identify organelles, distinguish between prokaryotic and eukaryotic cells, and infer likely cell functions from visible ultrastructure

describe the structure of viruses as acellular particles containing nucleic acid within a protein coat, and in some cases a lipid envelope and attachment proteins

explain the replication of viruses in host cells and evaluate why viruses are classified as non-cellular and can reproduce only inside living cells
