Photosynthesis Lab Report

Through this experiment, Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell, cytoplasmic streaming, and plasmolysis of Egeria densa. First, the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x, 10x and 30x. During the latter part of the experiment, the Egeria densa was observed using the microscope to understand the use of microscope by actually examining Egeria densa. The different types of cells of Egeria densa that were required to observe were the general cells, spinulose, a typical cell or idioblast, and base cell. Also, cytoplasmic streaming, and plasmolysis of the Egeria densa were observed and
Also, adjust the eyepiece by pushing close or separating them to the appropriate position.
Perform the same process by changing the degree of the objective lens and focus to be able to see the grid clearly.

Using Egeria densa, cut a leaf using a scissor and place it onto the slide glass using a forcep and using the droppers drop some water and place coverslip on top of the leaf by sliding the coverslip when placing on top to prevent air which produces bubbles. Place the slide glass on the stage, by moving the stage clip and move the coarse adjustment knob toward the experimenter to set the stage to the lowest. Use the 4x or 10x objective lens, so move the revolver to that and also the iris diaphragm lever matched to the objective lens. Then, adjust the stage using the coarse adjustment knob, the knob controlling the x-axis, the knob controlling the y-axis, and the fine adjustment knob to focus. Observe and sketch the different cells (spinulose cell, atypical cell, general cell, base cell, and the
