Lab 2: Animal and Plant Cells

Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells.

Question: What are the differences between multi and single celled plant and animal organisms?

Prediction:
Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall, cell membrane, nucleus, chloroplasts, vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible under the microscope will be; cell wall, cell membrane, nucleus, vacuole and cytoplasm. Tomato Cell: The parts of the tomato cell that will be visible will be; cell wall, cell membrane, nucleus, vacuole and cytoplasm. Paramecium Cell: The parts of the paramecium cell that will be visible will be; cell wall, cilia, nucleus and mitochondrion. Smooth Muscle Cell: The parts of the smooth muscle cell that will be visible will be; cell membrane, nucleus and mitochondrion.

Design: The first action taken in this lab was the recording of predictions of what will be visible in the cell under the microscope. The next action taken was viewing a spirogyra cell under a microscope at 40x magnification to focus it. Then the ocular lens was rotated to the 100x magnification and a picture was recorded of what was visible under such magnification, after the slide had been focused. After recording the picture, the ocular lens was rotated to 400x magnification and another picture was recorded of what was visible under the microscope, once again after the slide had been focused. After the 100x magnification and also the 400x magnification, and estimation was recorded of how many cells fit across the field of view. The same process was followed for the banana cell, tomato cell, paramecium cell and smooth muscle cell, with the tomato slide being stained with methylene blue solution, and the banana stained with Lugol's solution, both to highlight certain cell parts. The independent...
