Single - Cellular organisms. 1 of 20 What are Eukaryotes? Multi - Cellular organisms. 2 of 20 What is a Plasma Membrane? Found in plants and animals. Made of lipids and proteins. Regulates movement in and out of cells. Contains receptors for cell signalling. 3 of 20 What is the Cell Wall? Found in plants. Made of carbohydrates and cellulose. Supports plant cells. 4 of 20 What is a Nucleus? Found in plants and animals. Large organelle which contains cromotin and a nucleolus. 5 of 20 What is a Lysosme? Contains digestive enzymes that can be used to digest invading cells, or worn down components. 6 of 20 What is a Ribosome? Is either free floating or attached to RER. Where proteins are made. 7 of 20 What is the Rough Endoplasmic Reticulum (RER)? Folds and processes proteins that have been made in the ribosomes. 8 of 20 What is the Smooth Endoplasmic Reticulum (SER)? Synthesises and processes lipids. 9 of 20 What is the Golgi Apparatus? Processes and packages lipids. Makes lysosomes. 10 of 20 What is Mitochondria? Site of aerobic respiration. Where ATP is produced. 11 of 20 What are Chloroplasts? Where photosynthesis occurs. 12 of 20 What is Cilia? Microtubules that move substances along cell membrane. 13 of 20 What is Flagella ? Microtubules that propel cell foward. 14 of 20 What is the Cytoskeleton? Network of protein threads that run through the cell. Arranged in microfilaments and microtubules. 15 of 20 What are the functions of the Cytoskeleton? Support cells organelles. Strengthen cell to maintain shape. Transport organelles. Causes cell to move. 16 of 20 What is Magnification? How much bigger the image is than the specimen. 17 of 20 How do you calculate Magnification? Image size / Object size 18 of 20 What is Resolution? How well you can distinguish between two points that are close together. 19 of 20 What are the types of Microscopes? Light microscope and Electon microscopes. 20 of 20
