Question 1

All of the following are TRUE of fungi,EXCEPT

Accepted Answer

Fungi are not autotrophs, meaning they cannot produce their own food through photosynthesis like plants do. Rather, they are heterotrophs that obtain their nutrients by absorbing organic matter from their surroundings.

Question 2

Fungi evolved approximately

Accepted Answer

Fungi are believed to have evolved from a protist ancestor approximately 1 billion years ago. This is supported by genetic and fossil evidence. Option A is incorrect because fungi are much older than 200,000 years. Option B is also incorrect because protists themselves did not exist 4 billion years ago. Option C is incorrect because fungi are much older than 1 million years. Option E is incorrect because fungi are much older than 1 million years and did not evolve from a protist that recently.

Question 3

A protist is the common ancestor of

Accepted Answer

Protists are considered the most diverse and primitive eukaryotes, and all other eukaryotic groups, including plants, animals, fungi, and slime molds, are descendants of protists. Hence, the correct option is E, i.e., all of the above.

Question 6

Which term can be used to describe a protist?

Accepted Answer

A protist can be autotrophic (able to produce its own food), heterotrophic (obtaining food from other organisms), a decomposer (breaking down dead organic material), or a saprotroph (obtaining nutrients from dead organic material). Therefore, all of the above terms can be used to describe a protist.

Question 7

Which would NOT be considered a protist?

Accepted Answer

Saccharomyces cerevisiae is a fungus and not a protist. Protists are a diverse group of eukaryotic microorganisms that are not fungi, animals, or plants. The other options are all examples of protists.

Question 8

Which does NOT describe a member of the kingdom Fungi?

Accepted Answer

All of the options describe members of the kingdom Fungi, so E is incorrect.

Question 11

All of the following are true of algae,EXCEPT

Accepted Answer

Algae are not considered plants, as they lack certain characteristics found in true plants such as roots, stems, and leaves. They are unicellular or multicellular photosynthetic organisms that are typically found in aquatic environments.

Question 12

Protists are difficult to classify because

Accepted Answer

Protists share features with multiple kingdoms (plants, animals, fungi) but do not fit within any one of them perfectly, hence making classification difficult.

Question 13

Why are the protists so difficult to classify?

Accepted Answer

The answer of Why are the protists so difficult to...

Question 14

Which is NOT true of protists?

Accepted Answer

Protists are usually found in aquatic environments, not terrestrial areas.

Question 15

Accepted Answer

The answer of All species of fungi are
...

Question 16

Conservationists prefer to protect large,contiguous tracts of land rather than areas that are fragmented by roads,farmland,and other human-induced changes.Why are large,undisturbed areas better for protecting biodiversity?

Accepted Answer

The answer of Conservationists prefer to protect large,contiguous tracts of...

Question 17

Major threats to biodiversity include

Accepted Answer

Habitat loss and fragmentation by human activities and the expanding human population that leads to increasing demands for resources are the major threats to biodiversity. Therefore, options A, B, and C are all major contributors to the decline in biodiversity around the globe.

Question 18

An organism that is eukaryotic,multicellular,and heterotrophic is

Accepted Answer

Animals and fungi are both eukaryotic, multicellular, and heterotrophic, distinguishing them from plants, which are autotrophic.

Question 19

An organism that is eukaryotic,multicellular,and has cell walls is

Accepted Answer

Plants and fungi are both eukaryotic, multicellular organisms that have cell walls. However, the composition of their cell walls differs, with plants primarily having cellulose and fungi having chitin. Animals do not have cell walls, and while some protists may have cell walls, they are not typically multicellular in the same way plants and fungi are.

Question 20

An organism that is eukaryotic and photosynthetic is

Accepted Answer

Plants and some protists are eukaryotic and capable of photosynthesis. Fungi, however, are not photosynthetic; they absorb nutrients from their environment.
