3. Aggregation turns into a sluglike structure. 4. Sluglike structure moves toward light and eventually stops and forms a fruiting body that produces spores. 5. Fruiting body breaks down but spores survive and are spread by animals, wind, and water. 6. Spores germinate into single cells that exist as haploid amoebae.
3. They can be genetically engineered to produce insulin and other human hormones. 1. They spoil food, destroying timber, and causing diseases of crops, live stock, and humans. 2. Fungi cause the majority of plant diseases, which in turn cause serious economic loss. …
Microbiology Quiz 3. Which of the following is not a difference between endospores and vegetative cells? A) Vegetative cells are metabolically active, whereas endospores are dormant. B) Vegetative cells are more resilient due to their metabolic activities, whereas endospores are more sensitive to change. C) Vegetative cells normally have enzyme ...

Only some phyla of fungi can undergo sexual reproduction. This often involves the creation of a dikaryon cell: A cell with two haploid nuclei. Fungi produce three major types of sexual produced spores across the different phyla. Describe hyphae.
Fungi cause the majority of plant diseases, which in turn cause serious economic loss. Describe fungi reproduction. During the asexual phase, identical microscopic haploid spores are created be mitosis. When they land in the right conditions they germinate and grow new hyphae. Only some phyla of fungi can undergo sexual reproduction.
With animals fungi lack chloroplasts and with plants fungi have a cell wall and vacuoles, the produce sexually and asexually. To complete Step 8, use a pen or pencil to label the structures you identified in the Rhizopus slide images. ... Include your hypothesis from Step 5 here.
bactericide. Substance that kills bacteria. bacteriostatic. Prevents the growth of bacteria, but does not kill them. disinfectant. A chemical that destroys many, but not all, microbes. pasteurization. Brief heat treatment that reduces the number of spoilage organisms and destroys disease-causing microbes. preservation.
a) Disinfectants are chemicals that completely destroys all microbes on a product. Antiseptics are chemical s that reduce the number of microbes on a product. b) Disinfectants are chemicals that reduce the number of pathogenic microbes on an inanimate surface or object. Antiseptics are chemicals used to delay the spoilage ...
decontamination. reduces number of pathogens to a safe level. Healthcare-associated infection (HAI) infections acquired while receiving treatment in a hospital or other healthcare facility. disinfection by-products (DBPs) compounds formed when chlorine or other disinfectants react with natural chemicals in water.
preservation. Inhibition of microbial growth to delay spoilage. sterile. Free of all viable microbes, including endospores and viruses. sterilization. The destruction or removal of all microbes through physical or chemical means. decontamination. reduces number of pathogens to a safe level.
