Question 1
Multiple choiceWhich phylum do protozoans primarily belong to?
Explanation
Protozoans are classified under the phylum Protozoa, which consists of diverse unicellular organisms.
Question 2
Multiple choiceWhich of the following characteristics is NOT typical of fungi?
Explanation
Most fungi are heterotrophic and have cell walls made of chitin; they do not perform photosynthesis.
Question 3
Multiple choiceMetazoans are primarily characterized by their:
Explanation
Metazoans, also known as multicellular animals, are characterized by their multicellular organization.
Question 4
Multiple choiceWhich of the following represents a common reproductive method in fungi?
Explanation
Fungi typically reproduce through spore formation, which allows for dispersal and colonization of new environments.
Question 5
Multiple choiceWhich genus of protozoan is known for causing malaria?
Explanation
The genus Plasmodium is responsible for malaria, transmitted to humans through the bite of infected mosquitoes.
Question 6
Multiple choiceThe mycelium is a characteristic structure of which organism?
Explanation
Mycelium is a network of fungal filaments (hyphae) that is essential for nutrient absorption in fungi.
Question 7
Multiple choiceWhich of the following is NOT a classification of metazoans?
Explanation
Euglenozoa is a group of protists and not classified as metazoans, which are multicellular animals.
Question 8
Multiple choiceFungi obtain nutrition primarily by:
Explanation
Fungi are heterotrophs and absorb organic material from their environment for nutrition.
Question 9
Multiple choiceWhich structure in protozoans is primarily responsible for locomotion?
Explanation
Flagella are tail-like structures that provide motility to many protozoans.
Question 10
Multiple choiceWhich of the following metazoan phyla is known for having a body plan organized around a central cavity?
Explanation
The phylum Porifera, or sponges, have a simple body plan organized around a central cavity.
Question 11
Multiple choiceWhich genus of protozoan is commonly found in the intestines and can cause dysentery?
Explanation
The genus Amoeba, specifically Entamoeba histolytica, is known to cause amoebic dysentery.
Question 12
Multiple choiceWhat is one of the principal roles of fungi in ecosystems?
Explanation
Fungi play a crucial role as decomposers, breaking down organic material and recycling nutrients in ecosystems.
Question 13
Multiple choiceWhich of the following is a defining feature of unicellular protozoans?
Explanation
Protozoans are primarily defined by their unicellular organization, comprising individual cells that carry out all life processes.
Question 14
Multiple choiceWhich characteristic is common to both fungi and some protozoans?
Explanation
Both fungi and some protozoans (like chitin-containing species) show similarities, such as having chitin in their cell walls.
Question 15
Multiple choiceWhich of the following best describes the mode of life of most protozoans?
Explanation
Most protozoans can be free-living or exist as parasites, depending on the species and environmental conditions.
Question 16
Multiple choiceIn which phylum would you classify organisms that have radial symmetry and stinging cells?
Explanation
Cnidarians, such as jellyfish and corals, are known for their radial symmetry and possess stinging cells called nematocysts.
Question 17
Multiple choiceWhich growth form of fungi invades and decomposes organic matter externally?
Explanation
Molds are a type of fungi that grow by spreading mycelium and actively decompose organic matter externally.
Question 18
Multiple choiceWhich organism is classified as a metazoan?
Explanation
Hydra is a classic example of a metazoan, as it is multicellular and exhibits characteristics typical of animal life.
Question 19
Multiple choiceWhich of the following phyla is NOT classified under metazoans?
Explanation
Euglenozoa is classified as a phylum of protozoans, while Cnidaria, Platyhelminthes, and Arthropoda are all metazoan phyla.
Question 20
Multiple choiceWhich characteristic is most commonly associated with fungi?
Explanation
Fungi are primarily heterotrophic, absorbing nutrients from their environment, unlike plants which are autotrophic and have chlorophyll.
