1. We know fungi are eukaryotic (have membrane-bound nuclei and organelles). Explain three unique ways fungi are different from other microbes (algae, protozoans, bacteria, and archaea). Compare cell walls, cell membranes, morphology, reproduction, and life cycles. (Words to use in your answer include chitin, cellulose, peptidoglycan, pseudopeptidoglycan, ergosterol, hopanoids, cholesterol, mycelium, hyphae, multinucleate, multicellular, unicellular, nutritional needs, environmental needs, chemoheterotrophy, saprobes, parasites, free-living, reproductive strategies, spores). 2. Algae and protozoans are loosely grouped as protists and are different from plants because they lack specific characteristics of plants. Explain what differentiates algae from plants and two ways they are different from protozoans. Talk about algae being part of our environment and how algae may positively or negatively impact our health or the environment. (Words to use in your answer: cell wall, cell membrane,…

Which of these organelles is not found in a fungal cell? a. chloroplast b. nucleus c. mitochondrion d. Golgi apparatus
2. Bryozoan and Hydroid polyps share several apparent similarities with each other when it comes to shape, function, and behavior yet they are distinctly different in several ways as well. Your challenge is to identify two separate functions (ie feeding, exchange, protection, reproduction) that these structures are utilized for and then contrast how the polyp arrays are either used in a similar or different manner to achieve this goal. For the latter, you may consider such things as structure, mechanics, behavior etc. Your focus should be on the polyp itself and not on any structure(s) that house the polyp. To summarize - list two specific functions that polyp structures are used for. For each function, discuss similarities and differences in the way that bryozoans and hydroids use their polyps to achieve these functional goals.

Protists that have a pellicle are surrounded by ___________ . silica dioxide calcium carbonate carbohydrates proteins
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?
The cell walls of fungi are strengthened by chitin, a strong but flexible polysaccharide. Which of these statements about the function of chitin in fungal cell wall is TRUE? a. Chitin-rich walls of fungi improves feeding by facilitated diffusion. b. The movement of water and nutrients into fungal cells creates pressure that could cause them to burst if they were not surrounded by a chitin-rich cell wall. c. The chitin present in fungal cell wall does not impart any advantage in terms of nutrient acquisition from the environment. d. Chitinous tubular cell walls confers motility to multicellular fungi.
Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…
