Step by step
Solved in 3 steps
- A dikaryotic fungus will; Have two nuclei per cell lack crosswalls in its hyphae reproduce sexually by creating mushroomsAmoeba is a single cell prokaryote O True O FalseCan you please help label these parts of the amoeba. Nucleus Phagocytic Vacuole Contractile Vacuole Pseudopodium Cilia Pelicle Cytoproct Micronucleus
- Label the Amoeba and Identify whether it is eukaryote or prokaryote and Indicate the type of cellular reproduction process the cell undergoFind 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…Amoeba multiplies by mitotic cell division .is theis phenomena growth or reproduction explain?
- An organism is a mixotroph loses its plastids, it survives because of which reason; 1. It has an endospore and becomes dormant until conditions improve 2. It has photosynthesis by membranes present in the cytoplasm 3. since it is also a heterotroph engulfs organic material by phagocytosis or by absorption for nutrition 4. uses mitochondria that acquite after loosing its plastidsWhich parasitic protist evades the host immune system by altering its surface proteins with each generation? a. Paramecium caudatum b. Trypanosoma brucci c. Plasmodium falciparum d. Phytophthora infrstansDuring excystation (excysting) of Giardia which occurs in the lumen of small intestine: * O trophozoites are converted into cysts trophozoites represent dormant stage cysts release trophozoites O cysts multiply by binary fission all answers are correct rdıCdle ie dograded
- In 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…Jr. Scientist discovers a never-before-classified protist. It contains multinucleated filaments, similar to fungal hyphae however, upon closer examination the cell walls are found to be composed of cellulose rather than chitin. They do not perform photosynthesis but instead acquire nutrients by way of parasitism or decomposition. Jr. Scientist has likely discovered a rhizarian a foraminiferan an oomycete a mycetozoanThe Zygomycetes (bread molds) are a coenocytic fungus. This means that; Their hyphae lack crosswalls They only reproduce sexually They reproduce using conidia They have heterokaryotic hyphae
