Blane Smith Biology 104 October 10, 2007 Conclusion Questions 1. When a microscope increases in magnification, the viewing area gets smaller. This is because the lens is moving closer to the object being viewed and is cutting out the rest of the viewing field. The object does not get larger, the lens just gets closer. The field of visibility is more centralized in one spot. 2. Some of the cellular structures that can be observed with a compound light microscope include: Nuclei, Nucleoli, Cytoplasm, Chromoplasts, Chloroplasts, Vacuoles, and some of the other bodies within cells that are larger than 2 micrometers. With an electron microscope, those smaller bodies within cells can be seen even better than with a compound light microscope. An electron microscope can see up to 200,000 or more times of regular viewing ability. 3. The cell wall was first discovered by Robert Hooke in 1665. The cell wall is very unique because it is what defines the shape of a cell. The main structural component is cellulose. The plasma membrane is important because it

The cytoplasm in most living cells is located in the open area of each cell. It is what fills the empty space inside of a cell. 5. Vacuoles in a plant cell are very important. Vacuoles usually make up about 90% of a mature plants cell. They hold a watery fluid called cell sap which helps to maintain pressure within the cell. Vacuoles also aid in the breakdown and digestion of organelles, such as plastids and mitochondria. 6. Chromoplasts are different from chloroplasts because chromoplasts sometimes develop from chloroplasts through internal changes that include the disappearance of chlorophyll. All chloroplasts are chromoplasts but not all chromoplasts are chloroplasts because in order for it to be considered chloroplast, it must have chlorophyll or that green color to them.
