“Watennelon snow” in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae areaalsofound in high- altitude year-round snowfields. In both locations, UV light levels tend to be high. Based on what you learned in this chapter, proposc an explanation for why thisphotosyntheticalga appears reddish-pink.

O The fungus serves as the substrate the alga needs to perform mitosis, while the alga produces enzymes the fungus needs for decomposition. O The fungus produces the sugars the alga uses for cellular respiration, while the alga provides a safe place for the fungus to live. O The alga offers camouflage to the fungus against herbivory, while the fungus secretes toxic substances that release nutrients from the rocks to the alga. Mark this and return A lichen is an organism that is actually made of both a fungus and an alga. These organisms live together on rocks and other hard surfaces.

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…arrow_forward
