Summary Introduction
Slime molds belong to group amoebozoa which comes under kingdom Protista. Slime molds are motile and can be categorized into plasmodial slime molds (acellular slime molds) and cellular slime molds. Plasmodial slime molds represent cells which contain masses of indefinite size protoplasm called plasmodium, whereas cellular slime molds represent forms which are of single amoebae type. Dictyostelium and Physarum are two major members of slime molds.

- Explain how the definition of protists ensures that the kingdom Protista includes a wide diversity of cellular structures. Provide an example of two different structures that perform the same function for their respective protist.arrow_forwardIn the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions: Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments. Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments. Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments. Non-filamentous cyanobacteria generally produce spores…arrow_forwardIn the following diagram of a black bread mold (Rhizopus stolonifer), identify the following structures of a multicellular fungus: mycelium, rhizoids, stolon, sporangium, sporangiophore, sporangiospores. After that, give a brief description/function of each structure: 1. Hypha/Mycelium 2. Rhizoid 3. Stolon 4. Sporangium 5. Sporesarrow_forward

Ascomycete hyphae have simple pores in their septa and lack clampconnections, whereas basidiomycete hyphae display complex septalpores and clamp connections.b. Ascomycetes produce sexual spores in sacs, whereasbasidiomycetes produce sexual spores on the surfaces of clubshaped structures.c. Ascomycetes are commonly found in lichens, whereasbasidiomycetes are less commonly partners in lichen associations.d. Ascomycetes are not commonly mycorrhizal partners, butbasidiomycetes are commonly present in mycorrhizal associations.e.
