Question

DATE NAME SECTION/GROUP INSTRUCTOR DATA: EXERCISE 5 MAKING CONNECTIONS A. Plant Cell 1. Which magnification level gives you the best view of the leaf? 2. Can you see individual cells in your live leaf slide? If so, what makes them look individual? 3. What structures are visible in the live leaf slide? 4 What structures are visible in the stained prepared slide? B. Animal Cells 1. What level of magnification gives you the most information? Were there more structures visible in the prepared plant slide or the prepared animal cell slide? 2. Exercise S Cell Structure: Observing Cells under a Microscope 57 3. What cell structures do you find in plant cells that are not found in animal cells? What cell structures do you find in animal cells that are not found in plant cells? 4. Conclusion 1. Which structures were visible with the light microscope? 2. What is the biochemical makeup of the structures you could see? Those you could not see? 3. What factors, other than staining, are important in visualizing intracellular structures?

Answer 1

1. Most microscopes have a 10x (10-power magnification) eyepiece and three objective lences of 10x and 40x and 100x to provide magnification levels of 100x and 400x and 1000x . The Magnification of 400x is the best level for best view leaf cell structure.

2. Yes, individual cells of live leaf can be seen.  

By using ta compound light microscopes individual live leaf cells can be seen. We can see the individual live cells due to the presence of resolution power of microscopes. Resolution power of microscope can distinguished minimum distance between two cells or two points.

3. All of the anatomical structures are visible in a stained prepared cells, such as cell wall, membrane, cytoplasm,organelles(if high resolution power is very high), various types of cells(parenchaymatous,pallisade,spongy cells, vascular bundles(xylem,phloem), cortex,pith,medullary rays etc.

B.

1. The magnification is varies from one microscope to another. But mostly 1000x(10x eyepiece * 100x objective lence) provide more information than 400x(10x eyepiece * 40x objective lence).

2. In stem cell more structures are visible in case of animal cell and in plants vegetative cells provide more informations.

3. Cell wall, vacuoles, chloroplast are found in plant cell but not in animal cell.

4.centrosome,lysosome present in animal cell but not in plant cell.
