Lab 2 cell structure and function experiment 2

We can see those organelles due to the fact that they are the largest organelles in the cell and also due to the dye which brought them out. The 6H as well as the previously produced 4H and 2H will now be used as reactants in the last stage, and 3O2 oxygen molecules are also added in as reactants in the formula.

Leave the stain on the slide for 1 minute. When you stain your cheek cells, you should be able to distinguish between the nucleus, cytoplasm, cell membrane. Cheek cells are epithelial cells that line the interior surface of our mouths. The onion's large cells can be seen easily under a microscope and also used to teach the fundamentals of cell biology.

The cytosol also carries inclusions, which are starches, proteins and other elements that act as building blocks for a number of functions. When we viewed the cheek cells at 40X total magnification, we noticed that the cells were secluded and spread out see diagram provided.

Blot your slide with bibulous paper. What is the function of a lysosome? Stained human cheek cells. In The Biology Lab Primer, you will Draw a representative onion epidermal cell identifying the following structures: The phloem tubes then transport the glucose down to all parts of the plant.

After 30 seconds, wash off with a gentle stream of water. Cilia have three uses: The onion skin cell, an example of a plant cell, generally has a rigid, rectangular shape.

Glossary of Biological Terms

Methylene blue will stain the sample, allowing visualization of the nucleus, cytoplasm, and even some organelles. Part Three - Labeling the Diagram Label the diagram below with the following parts: Below is a simplified version of eukaryotic organelles.

However, most of the ATP produced from glucose is derived from hydrogens that are released as glucose is metabolized. How would you classify this paramecium: If someone knows about the cell and how it works they could find a way to counteract viruses and illnesses, thus creating medicine and a way to cure the virus or illness.

The final statement in my hypothesis was that the overall image will not be clear enough for further detail. The pellicle is a stiff, outer covering that helps give the paramecium its shape.

This organelle is involved in cellular respiration and is capable of producing up to a net of 38 ATP the universal currency of energy of all cells from a single glucose molecule. Where is the DNA housed in a prokaryotic cell? The Krebs Cycle This is the first stage that uses oxygen.

Press down on the coverslip and remove excess methylene blue with a paper towel. What is the difference between the rough and smooth endoplasmic reticulum?

How did the surface area affect the diffusion of the block?The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue.

2 Laboratory 4: Plant Structure OBJECTIVES After completing this lab you will be able to: 1. Differentiate between dicots and monocots within the following (2o) cell walls which are often lignified.

Fibers, however, are long unbranched cells which are normally dead They are often found in vascular tissue where they function in support.
