Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

What will happen to the rate of contractile vacuole function if the paramecium is placed in a: a) 100% water solution - Water will move rapidly into the Paramecium. The contractile vacuole will have to pump faster and faster to keep out excess water. If too much water enters the cell‚ cytolysis

Biology 1003 - Cells: Size‚ Structure and Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the

Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the
