    • C.

      Ciliates

    • D.

      Spore-forming

    Correct Answer
    A. Amoebalike
    Explanation
    Amoebalike protists move by means of pseudopods, which are temporary extensions of the cell membrane that allow them to move and engulf food particles. Pseudopods are formed by the protrusion of cytoplasm, and they can be extended and retracted in different directions, enabling the protist to change its position. This mode of movement is characteristic of amoebas, which belong to the group of amoebalike protists. Flagellates, ciliates, and spore-forming protists have different mechanisms for locomotion and do not use pseudopods.

    Protists are both producers and consumers.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Protists are both producers and consumers because they have the ability to perform photosynthesis and produce their own food like plants (producers), as well as consume other organisms for energy like animals (consumers). This dual role allows them to occupy various ecological niches and play important roles in food webs and nutrient cycling in aquatic ecosystems.

    Green algae is green because chlorophyll is the main pigment contained.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Green algae is green because chlorophyll is the main pigment contained. Chlorophyll is a green pigment that is responsible for the process of photosynthesis in plants and algae. It absorbs light energy from the sun and converts it into chemical energy, which is used for growth and development. Green algae, like other photosynthetic organisms, contain chlorophyll in their cells, giving them their characteristic green color. Therefore, the statement is true.

    Plant like protists are also known as algae.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Plant-like protists, also known as algae, are a diverse group of organisms that possess characteristics of both plants and protists. They are photosynthetic, meaning they can produce their own food using sunlight, just like plants. Algae can be found in various habitats, including freshwater, saltwater, and even on land. They play a vital role in ecosystems as primary producers, providing food and oxygen for other organisms. Therefore, the statement "Plant-like protists are also known as algae" is true.

    Parameciums are a type of ciliate.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Parameciums are indeed a type of ciliate. Ciliates are a group of protozoa that possess hair-like structures called cilia, which they use for locomotion and feeding. Paramecium is a well-known example of a ciliate, characterized by its elongated shape and numerous cilia covering its surface. These organisms are commonly found in freshwater environments and play important roles in aquatic ecosystems.

    Fungi:

    • A.

      Are all producers

    • B.

      Cannot eat or engulf food

    • C.

      Only found in soil

    • D.

      Mostly single-celled

    Correct Answer
    B. Cannot eat or engulf food
    Explanation
    Fungi cannot eat or engulf food because they are heterotrophic organisms that obtain nutrients by absorbing them from their surroundings. Unlike producers, which can synthesize their own food through photosynthesis, fungi rely on external sources of organic matter for their nutrition. They secrete enzymes that break down complex organic compounds into simpler forms, which they can then absorb and use for energy. This characteristic sets fungi apart from producers and highlights their role as decomposers in ecosystems.

    Lichen:

    • A.

      Is a parasite

    • B.

      Made of an alga and fungus intertwined

    • C.

      Lives in water only

    • D.

      Is a consumer

    Correct Answer
    B. Made of an alga and fungus intertwined
    Explanation
    Lichen is not a parasite but a symbiotic organism made up of an alga and fungus living together in a mutually beneficial relationship. The alga provides food through photosynthesis, while the fungus provides structure and protection. This unique combination allows lichen to thrive in a variety of environments, including on rocks, trees, and soil.

    Which is NOT true about fungi?

    • A.

      All are consumers

    • B.

      All are multicellular

    • C.

      Are eukaryotic

    • D.

      Can be useful to humans

    Correct Answer
    B. All are multicellular
    Explanation
    Fungi are a diverse group of organisms that can be either multicellular or unicellular. While most fungi are multicellular, there are some unicellular fungi, such as yeast. Therefore, the statement that "all fungi are multicellular" is not true. Fungi can also be consumers, as they obtain nutrients by decomposing organic matter. They are eukaryotic organisms, meaning their cells have a nucleus. Additionally, fungi can be useful to humans in various ways, such as in the production of food, medicine, and biofuels.

      Imperfect fungus

    • D.

      Club fungus

    Correct Answer
    B. Sac fungus
    Explanation
    Yeast is classified as a sac fungus. Sac fungi, also known as Ascomycota, are characterized by their sac-like structures called asci, which contain spores. Yeast belongs to the genus Saccharomyces and is commonly used in baking and brewing due to its ability to ferment sugars. It reproduces asexually through budding, where a small daughter cell grows off the parent cell. Sac fungi are diverse and include many other species that play important roles in ecosystems, such as morel mushrooms and truffles.

    Yeast reproduce:

    • A.

      By conjugation

    • B.

      By budding

    • C.

      By fission

    Correct Answer
    B. By budding
    Explanation
    Yeast reproduce by budding, which is a type of asexual reproduction. In this process, a small bud forms on the parent yeast cell, gradually grows in size, and eventually separates to become a new individual yeast cell. This method allows yeast to rapidly increase their population size under favorable conditions. Conjugation, on the other hand, is a form of sexual reproduction, and fission refers to the splitting of a cell into two equal parts, neither of which is applicable to yeast reproduction.
