CELL STRUCTURE CELL THEORY: Structural and functional unit of all living things New cells arise from already existing cells Cells contain information that instructs growth. This information can be passed onto new cells. MICROSCOPES: There are two main types of microscopes: Light and Electron Electron Micrographs- shown in colour LIGHT ELECTRON Uses beam of light Magnification = x1500 Resolution = 200 nm Wide range of specimens can be used Samples are fairly quick + easy to prepare

Cells are made of many organelles‚ these include the Nucleus‚ DNA‚ Ribosomes‚ Lysosomes‚ Mitochondrion‚ Vacuoles‚ Cytoplasm‚ Endoplasmic‚ Golgi‚ and the Cell Membrane. There is one specific job of each organelle in a cell. The Nucleus is basically the control

Biology Notes 1. Organisms are made of cells that have similar structural characteristics. 1 Outline the historical development of the cell theory‚ in particular the contributions of Robert Hooke and Robert Brown. The development of the cell theory starts in the 1600ʼs with Robert Hookeʼs discovery of cells when viewing a piece of cork under a microscope and describing them as a nun house. Anton van Leeuwenhoek was crucial in the development of microscopes making simple microscopes through advanced
