    A protozoan that moves by beating hairlike parts that cover its cell:

    • Colony

    • Pseudopodia

    • Ciliate

    Correct Answer
    A. Ciliate
    Explanation
    A ciliate is a type of protozoan that moves by beating hairlike parts that cover its cell. This movement is facilitated by tiny hair-like structures called cilia, which cover the surface of the ciliate's cell. These cilia beat in a coordinated manner, creating a wave-like motion that propels the ciliate through its environment. This movement allows the ciliate to find food, escape from predators, and navigate its surroundings effectively. Therefore, the correct answer is ciliate.

    Extensions of a protozoan's plasma membrane which function in getting food and in locomotion are called:

    • Alternation of generations

    • Pseudopodia

    • Asexual reproduction

    Correct Answer
    A. Pseudopodia
    Explanation
    Pseudopodia are extensions of a protozoan's plasma membrane that function in both obtaining food and facilitating movement. These temporary projections allow the protozoan to surround and engulf its food, as well as to move by extending and retracting these pseudopodia. This mechanism is commonly observed in amoebas, which use pseudopodia for both feeding and locomotion. Therefore, pseudopodia is the correct answer in this context.

    The diploid form of an alga that develops from a zygote and produces spores is:

    • Algae

    • Sporophyte

    • Lichen

    Correct Answer
    A. Sporophyte
    Explanation
    The correct answer is sporophyte. The question is asking for the diploid form of an alga that develops from a zygote and produces spores. A sporophyte is a diploid organism that undergoes meiosis to produce haploid spores. In the life cycle of many algae, the sporophyte stage is the dominant phase, where it produces spores that eventually develop into haploid gametophytes. This is in contrast to the gametophyte stage, which is haploid and produces gametes.

    Which of the following is a common feature shared by fungi?

    • Cellulose cell walls

    • Heterotrophic nutrition

    • Unicellular organization

    Correct Answer
    A. Heterotrophic nutrition
    Explanation
    Fungi are organisms that obtain their nutrients through heterotrophic nutrition, meaning they absorb nutrients from organic matter in their environment. Unlike plants, fungi do not perform photosynthesis. Additionally, fungi typically have chitin cell walls, another characteristic that distinguishes them from plant cells with cellulose cell walls.

    In slime molds, the mass of cytoplasm that contains many diploid nuclei but no cell walls or membranes:

    • Plasmodium

    • Ciliate

    • Colony

    Correct Answer
    A. Plasmodium
    Explanation
    Plasmodium is the correct answer because it refers to the mass of cytoplasm in slime molds that contains multiple diploid nuclei but lacks cell walls or membranes. This structure allows for the movement and feeding of slime molds, as well as the formation of spore-producing structures. Ciliate and colony do not accurately describe this specific characteristic of slime molds.

    Life cycle of organisms that have a haploid stage followed by a diploid stage is:

    • Alternation of generations

    • Sporophyte

    • Gametophyte

    Correct Answer
    A. Alternation of generations
    Explanation
    The correct answer is "alternation of generations." This refers to the life cycle of organisms that have both haploid and diploid stages. In this life cycle, the organism alternates between a multicellular diploid stage called the sporophyte, which produces haploid spores, and a multicellular haploid stage called the gametophyte, which produces gametes. This cycle allows for genetic variation and reproduction in these organisms.

    What is a defining characteristic of protists?

    • Multicellular organization

    • Presence of a true nucleus

    • Chitin cell walls

    Correct Answer
    A. Presence of a true nucleus
    Explanation
    Protists are characterized by the presence of a true nucleus within their cells. Unlike prokaryotes, such as bacteria, protists have a well-defined membrane-bound nucleus that encloses genetic material. This feature distinguishes them from other microorganisms.

    In mushrooms this take place in the gills:

    • Meiosis

    • Mitosis

    • Digestion

    Correct Answer
    A. Meiosis
    Explanation
    Meiosis is the correct answer because it is the process of cell division that occurs in the reproductive organs of organisms, such as mushrooms. In mushrooms, meiosis takes place in the gills, which are the structures responsible for producing spores. Meiosis is important for the production of genetically diverse spores, which can then germinate and give rise to new individuals.

    A kind of reproduction in which a single parent produces offspring identical to itself:

    • Ciliate

    • Fragmentation

    • Asexual

    Correct Answer
    A. Fragmentation
    Explanation
    Fragmentation is the correct answer because it is a type of reproduction in which a single parent organism breaks into fragments, and each fragment develops into a new individual that is genetically identical to the parent. This process is commonly observed in simple organisms like bacteria, fungi, and some plants. It allows for rapid reproduction and colonization of new habitats, as each fragment can grow into a new individual without the need for fertilization or the involvement of another parent.
