In the space below, diagram generalized haplontic, diplontic, and alternation of generations life cycles. Make sure to indicate whether each stage in the life cycle is haploid or diploid, and unicellular or multicellular. Also write the stage's name (e.g., zygote, gametophyte, spore, etc.) if it has one. You don't need to draw the stages - e.g., for a zygote you can just write "zygote, unicellular, 2N". Also make sure to indicate where exactly in the life cycle meiosis takes place. Please draw and label these as possible clearly as Haplontic Diplontic Alternation of generations

Find the large nucleus located near the cell. 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…

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.
