2.3: Eukaryotic Cells Topic 2: Cells Miss Friedman
2.3.1: Draw and label a diagram of the ultrastructure of a liver cell as an example of an animal cell Include: • Endoplasmic reticulum (ER) • Ribosomes • Lysosomes • Golgi apparatus • Mitochondria • Nucleus • Centrosomes • Vacuoles
2.3.6: Roles of extracellular components • Extracellular matrix (ECM) is composed of collagen fibres (a protein) plus a combination of sugars and proteins called glycoproteins • These form box-like structures that anchor the matrix to the plasma membrane • The ECM allows for cell-to-cell interaction • Many researchers think the ECM is involved in directing stem cells to differentiate
