Lab 2 cell structure and function experiment 2

Materials The materials that were used in this lab are: As with the amoeba, the contractile vacuole collects and removes excess water.

The same processes are true for paramecium. Play it several times if you like. Cells require energy for active transport, synthesis, impulse conduction nerve cellscontraction muscle cellsand so on.

Onion Root Cell Cycle Lab Answers

In this stage the chromosomes reached the centrioles and a nuclear membrane begins to form around each nucleus. The net result is that nothing changed. Which bag increased the most in volume? 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.

How to remember which way xylem and phloem flow. They are 2 the formation of acetyl coenzyme A, 3 the Krebs cycle, and 4 the electron transport system. Overall, I have learned that onion skin cells plant cells are rectangular and are always with other plant cells and cheek cells animal cells are circular and are secluded from each other, and that the smaller organelles cannot be seen with just our school microscope.

What about the surface area to volume ratio? Instead, use the methylene blue solution as the dye Observations When observing the onion skin cell, we noticed that the cells took on a brick-like structure and within the cells, small dots the nuclei can be seen.

Then, on the inside of the cell, ATP Adenosine TriPhosphate binds to another site on the carrier and phosphorylates adds one of its phospate groups, or -PO4, to one of the amino acids that is part of the carrier molecule. What appears to be the cell membrane is actually a part called the pellicle.

This stage produces the most energy of all four stages. As these electron transfer reactions occur, energy is released that is used to pump the hydrogen ions across that membrane and into the area between the two mitochondrial membranes. Due to the fact that the cheek cell was not in groups or clumps, the arrangement of this type of cell is unknown.

Remember, the catalyst for plants is chlorophyll. The acetyl coenzyme A is used as a reactant in the next stage, but the hydrogen and carbon dioxide are not. Like the last two specimen, this was viewed in X magnification.

At X total magnification, we were only able to view one cell at a time, due to the fact that the cells were separated from each other. Unlike the onion skin cells, the cheek cells were more spread out from each other and they all had a round shape.

The same applies to guard cells.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.

Lab 2 Cell Structure and Function BIOL Student Name: Edwina Addo Dankwa Kit Code (located on the lid of your lab kit): Pre-Lab Questions 1. Identify three major similarities and differences between prokaryotic and eukaryotic cells. The similarities are both have DNA, ribosomes and membrane bound%(38).

Lab 2- Bio - 1 - Name: _____ Prokaryotic and Eukaryotic Cells OBJECTIVES • To explore cell structure and morphology in prokaryotes and eukaryotes. • To gain more experience using the microscope, and in particular, to learn how to use the oil Understanding the nature of cell structure and function is important to an.

Exploring Cell Size Read the entire procedure and answer the pre-lab questions before proceeding with the lab activity. In this activity, you will measure the size of a period at the end of a sentence and then.

Onion Root Cell Cycle Lab Answers. You are here: Home; Science; Biology; When observing the onion root tip cells for the stage of prophase, the cells took on a brick-like structure and within the cells, small dots (the nuclei) can be seen.

In one particular cell’s nucleus, the chromatin has condensed so much that it can be seen using a. Plant & Animal Cells Staining Lab Answers.

You are here: The animal cell structure is the most prominent in human cheek cells. The onion skin cell, an example of a plant cell, generally has a rigid, rectangular shape.

is still commenting here but I’m doing an assignment in college and I need help on the clear objectives of this.
