AS Biology overview

Cells, Exchange and Transport Microscopes Cell Structures Membranes Cell Signals New Cells Cell specialisation What is the cell cycle? Mitosis Meiosis What are the organelles? What do they do? Structure and function The fluid mosiac model Crossing membranes Specialised cells organising the organism Cooperation between cells How do we know about cells? Magnification Types of microscope Transport in Animals Transport in plants Blood Lungs Xylem Phloem Transpiration Heart Lungs as exchange organs Tissues in the lungs Measuring lung capacity The mammalian heart The cardiac cycle Control of the cardiac cycle Blood vessels Body fluids Carrying oxygen Carrying carbon dioxide Xylem and phloem Water and plants Water uptake and movement Translocation-the movement of sugars Transpiration Reducing water loss Unit 1 Unit 2 Unit 3 AS Biology Molecules, Biodiversity,
