Protist & Fungi Questions and Answers
- 1.
The haploid form of an alga that produces gametes is called:
- A.
Gametophyte
- B.
Pseudopodia
- C.
Stolons
Correct Answer
A. GametophyteExplanation
The correct answer is gametophyte. In the life cycle of an alga, the gametophyte is the haploid stage that produces gametes. This stage is responsible for the production of reproductive cells, such as eggs and sperm, which will later fuse to form a diploid zygote. The gametophyte is typically a distinct and independent organism from the diploid sporophyte stage.Rate this question:

Extensions of a protozoan's plasma membrane which function in getting food and in locomotion are called:
- A.
Alternation of generations
- B.
Pseudopodia
- C.
Asexual reproduction
Correct Answer
B. PseudopodiaExplanation
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.Rate this question:

What is a defining characteristic of protists?
- A.
Multicellular organization
- B.
Presence of a true nucleus
- C.
Chitin cell walls
Correct Answer
B. Presence of a true nucleusExplanation
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.Rate this question:

Life cycle of organisms that have a haploid stage followed by a diploid stage is:
- A.
Alternation of generations
- B.
Sporophyte
- C.
Gametophyte
Correct Answer
A. Alternation of generationsExplanation
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.Rate this question:

The diploid form of an alga that develops from a zygote and produces spores is:
- A.
Algae
- B.
Sporophyte
- C.
Lichen
Correct Answer
B. SporophyteExplanation
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.Rate this question:

A protozoan that moves by beating hairlike parts that cover its cell:
- A.
Colony
- B.
Pseudopodia
- C.
Ciliate
Correct Answer
C. CiliateExplanation
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.Rate this question:

Which of the following is a common feature shared by fungi?
- A.
Cellulose cell walls
- B.
Heterotrophic nutrition
- C.
Unicellular organization
Correct Answer
B. Heterotrophic nutritionExplanation
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.Rate this question:

A kind of reproduction in which a single parent produces offspring identical to itself:
- A.
Ciliate
- B.
Fragmentation
- C.
Asexual
Correct Answer
B. FragmentationExplanation
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.Rate this question:

In slime molds, the mass of cytoplasm that contains many diploid nuclei but no cell walls or membranes:
- A.
Plasmodium
- B.
Ciliate
- C.
Colony
Correct Answer
A. PlasmodiumExplanation
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.Rate this question:

In mushrooms this take place in the gills:
- A.
Meiosis
- B.
Mitosis
- C.
Digestion
Correct Answer
A. MeiosisExplanation
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.Rate this question:
