- Which of the following statement(s) is/are TRUE? a. yeasts are unicellular fungi b. molds and mushrooms are filamentous fungi. The filaments are chains of cells called "hyphae" C. most protozoa are unicellular, animal-like members of Domain Archaea, many of which are motile and lack cell walls d. algae have historically been described as "plant-like" protists because they contain chloroplasts and cell walls e. organisms which make chlorophyll a can perform oxygenic photosynthesis f. all organisms which make chlorophyll a have chloroplasts g. Nostoc, algae and plants all make chlorophyll a and all have chloroplasts h. Nostoc, algae and plants have mitochondria which evolved from primitive endosymbiotic bacteria i. Photoautotrophs perform photosynthesis and chemoheterotrophs require pre-formed organic molecules as a source of carbon and energy j. Cyanobacteria, algae and plants are photoautotrophs. Fungi, protozoa and animals are chemoheterotrophs k. Most bacteria, all fungi, all algae…Discuss the characteristics of fungus-like protists that make them similar to true fungi.Discuss why the slime molds and water molds are not considered true fungi and what they have in common with other members of Kingdom Protista.
- Twenty years ago, Pneumocystis jirovecii, a pathogen of immunocompromised patients that causes pneumonia, was classified as a protozoan because it is a chemoheterotroph that lacks a cell wall. However, taxonomists today classify Pneumocystitis as a fungus. Why do you think it was originally misclassified?Match the following description or given species to the correct phylum/division of Kingdom Protista or Kingdom Fungi. Match each item to a choice: causative agent of red tide Rhizopus stolonifer extracted carageenan used in toothpaste and cosmetics where unicellular fungi belong possessing pseudopodia most evolutionary advanced fungi unicellular protist having both animal and plant characteristic Plasmodium malariae belongs to fungus-like protists Paramecium sp. Choices: : Oomycota : Euglenozoa : Myzozoa : Apicomplexa : Mucoromycota : Amoebozoa i Ascomycota : Ciliophora : Basidiomycota : Rhodophyta1) Make a graphic/visual organizer of the four supergroups of Protists and the major groups of protists. 2) The graphic organizer must include all the following major groups. Include one example organism and one derived character (shared by most or all members of the group).

Phytophthora infrstansSome literature lists the 4 groups of protozoans as: 1) Flagellates 2) Amoebas 3) Ciliates 4) Sporozoans But other sources list the 4 groups as: 1) Flagellates 2) Amoebas 3) Heliozoans 4) Ciliates Compare and contrast heliozoans vs. sporozoans. Explain why one would replace the other in literature sources.A) Define the coelom and 1. describe its function. B) Give examples of an animal phyla that exhibit all the variation in coelom evolution. 2.

- Identify from the list below the protists that function almost like multicellular organisms when food is depleted, forming a multicellular mass that forms fruiting bodies. A. slime molds B. oomycetes C. cercozoans D. diatomsTo which phylum do you think the Penicilium and Aspergillus fungi belong to?. Please explain what are conidia and what is their function. amswer the following in 3-6 sentences.Health professionals refer to fungal skin diseases as “tineas” and name them according to the region affected (TABLE 23.1). Fungal skin diseases are persistent, in part because fungi can penetrate deeper layers of skin than can ointments and creams. There are fewer antifungal drugs than antibacterial ones, and antifungals often have more severe side effects. Reflect on the evolutionary relationships among bacteria, fungi, and humans. Why it is harder to fight fungi than bacteria?
