BIOLOGY SL SYLLABUS DETAILS Topic 1: Cells 1.1 Cell theory 1.1.1 Discuss the theory that living organisms are composed of cells. 1.1.2 State that a virus is a non-cellular structure consisting of DNA or RNA surrounded by a protein coat. 1.1.3 State that all cells are formed from other cells. 1.1.4 Explain 3 advantages of using light microscopes. 1.1.5 Outline the advantages of using electron microscopes. 1.1.6 Define organelle. 1.1.7 Compare the relative sizes of molecules, cell membrane thickness, viruses, bacteria, organelles and cells, using appropriate SI units. 1.1.8 Calculate linear magnification of drawings. 1.1.9 Explain the importance of the surface area to volume ratio as a factor in limiting cell size. 1.1.10 State that unicellular organisms carry out all the functions of life. 1.1.11 Explain that cells in multicellular organisms differentiate to carry out specialised functions by expressing some of their genes but not others. 1.1.12 Define tissue, organ and organ system. 1.2 Prokaryotic cells 1.2.1 Draw a generalized prokaryotic cell as seen in electron micrographs. 1.2.2 State one function for each of the following: cell wall, plasma membrane, mesosome, cytoplasm, ribosome and naked DNA. 1.2.3 State that prokaryotes show a wide range of metabolic activity including fermentation, photosynthesis and nitrogen fixation. 1.3 Eukaryotic cells 1.3.1 Draw a diagram to show the ultrastructure of a generalized animal cell as seen in electron micrographs. 1.3.2 State one function of each of these organelles: ribosomes, rough endoplasmic reticulum, lysosome, Golgi apparatus, mitochondrion and nucleus. 1.3.3 Compare prokaryotic and eukaryotic cells. 1.3.4 Describe 3 differences between plant and animal cells. 1.3.5 State the composition and function of the plant cell wall. 1.4 Membranes 1.4.1 Draw a diagram to show the fluid mosaic model of a biological membrane. 1.4.2 Explain how the hydrophobic and hydrophilic properties of phospholipids help to maintain the structure of cell membranes. 1.4.3 List the functions of membrane proteins including hormone binding sites, enzymes, electron carriers, channels for passive transport and pumps for active transport. 1.4.4 Define diffusion and osmosis. 1.4.5 Explain passive transport across membranes in terms of diffusion. 1.4.6 Explain the role of protein pumps and ATP in active transport across membranes. 1.4.7 Explain how vesicles are used to transport materials within a cell between the rough endoplasmic reticulum, Golgi apparatus and plasma membrane. 1.4.8 Describe how the fluidity of the membrane allows it to change shape, break and reform during endocytosis and exocytosis. l.5 Cell division
