    Digestion that takes place outside the cell is called what? _________digestion

    Explanation
    Extracellular digestion refers to the process of digestion that occurs outside the cell. In this type of digestion, enzymes are secreted into the external environment to break down food particles into smaller molecules that can be absorbed by the organism. This process is commonly found in organisms such as fungi, bacteria, and some animals. By digesting food outside the cell, organisms are able to obtain nutrients and energy more efficiently.

    What is the part of the fungus called that is responsible for extracellular digestion and absorption of digested food?

    Explanation
    The mycelium is the part of the fungus that is responsible for extracellular digestion and absorption of digested food. It is a network of thread-like structures that spread out and penetrate the substrate, secreting enzymes to break down organic matter. The mycelium then absorbs the nutrients from the digested food, allowing the fungus to obtain energy and grow.

    Rate this question:

  • 11. 

    A specialized aerial hypha that produces spores is termed what?

    Explanation
    A specialized aerial hypha that produces spores is called a sporophore. A sporophore is a structure that is specifically adapted for the production and dispersal of spores in fungi. It is formed by the hyphae of the fungus and can vary in shape and size depending on the species. The sporophore plays a crucial role in the reproductive cycle of fungi by producing and releasing spores into the environment, allowing for the dispersal and propagation of the fungus.

    Extracellular digestion is common to the majority of fungi.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Extracellular digestion is a process where fungi secrete enzymes outside of their cells to break down organic matter, which they can then absorb and use as nutrients. This process is indeed common to the majority of fungi. They release enzymes into their environment, such as soil or decaying organic material, to break down complex molecules into simpler forms that can be easily absorbed by the fungi. This allows them to obtain nutrients and energy from their surroundings. Therefore, the statement "Extracellular digestion is common to the majority of fungi" is true.

  • 14. 

    Septate hyphae lack a dividing cell wall between nuclei.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Septate hyphae actually have a dividing cell wall between nuclei. This is what differentiates them from aseptate hyphae, which do not have any dividing cell walls. The septa, or cross walls, in septate hyphae separate the hyphae into individual cells, each containing one or more nuclei. These cell walls help to compartmentalize the hyphae and allow for more efficient nutrient transport and resource allocation within the fungus. Therefore, the correct answer is False.

    A haustorium invades the cells of a living host to absorb food directly from the cytoplasm.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A haustorium is a specialized structure found in parasitic plants that invades the cells of a living host. It penetrates the host's cells and absorbs nutrients directly from the cytoplasm, bypassing the normal process of digestion. This allows the parasitic plant to obtain food and energy from the host plant without having to go through the usual methods of nutrient absorption. Therefore, the statement that a haustorium invades the cells of a living host to absorb food directly from the cytoplasm is true.

    The main difference between shelf fungi, puffballs, and mushrooms is the way they form their spores.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Shelf fungi, puffballs, and mushrooms differ in the way they form their spores. Shelf fungi release their spores from the undersides of their shelves, puffballs release spores when they are disturbed or stepped on, and mushrooms release spores from their gills. Therefore, the statement that the main difference between these three types of fungi is the way they form their spores is true.

    An example of an alternate host used by a type of fungi is the barberry bush.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Fungi often have multiple hosts in their life cycle, with one host being the primary host and others being alternate hosts. In the case of the barberry bush, it is an alternate host for a type of fungi. This means that the fungi can infect and reproduce on the barberry bush, even though it is not their primary host. Therefore, the statement "An example of an alternate host used by a type of fungi is the barberry bush" is true.

    Drying or raking the ground daily will kill slime molds.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Drying or raking the ground daily can kill slime molds because slime molds thrive in moist environments. By removing moisture from the ground, slime molds are deprived of the conditions necessary for their growth and survival. Additionally, raking the ground disrupts the slime molds' structure and disperses them, further hindering their ability to thrive. Therefore, regularly drying or raking the ground can effectively eliminate slime molds.

    An organism that eats its food and digests it probably belongs to kingdom Fungi?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because organisms that eat their food and digest it do not necessarily belong to the kingdom Fungi. While some fungi do obtain nutrients by absorbing organic matter from their surroundings, there are also organisms in other kingdoms, such as animals in the kingdom Animalia, that eat and digest their food. Therefore, the ability to eat and digest food is not exclusive to fungi.

    Imperfect Fungi have no known mode of sexual spore formation.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Imperfect fungi are a group of fungi that do not have a known mode of sexual spore formation. This means that they do not reproduce sexually by forming specialized structures for the production and dispersal of sexual spores. Instead, they reproduce asexually through processes such as fragmentation, budding, or the production of asexual spores called conidia. Therefore, the statement "Imperfect fungi have no known mode of sexual spore formation" is true.
