Make several outline drawings to illustrate the successive changes of 1. shape of the amoeba. Make drawings of the Amoeba you observe, and label its structures. C O O liko mer 0 AS 6 0 O Paramecium -- Paramecia are quite large, straw-colored, slipper-shaped and move rapidly, and they are thus very noticeable. If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again. Often, Paramecia tend to move to the edges of the coverslip, and even "escape" the coverslip at its edges. The trick to slowing the Paramecia is to mix a drop of methyl cellulose with a drop of the cell culture, as…Evolution of Photosynthetic Organisms Algae are autotrophs and can have photosynthesis, however, evolutionary evidence suggests that plants shared a common ancestor with only green algae and are closest relatives of Charophytes. What evidences support this statement? How an algal cell is different from fungal cells, even if both are eukaryotes? Why slime mold is a protist not a fungus even if it does not have chloroplast?
