Question 1 of 10

Question 1

Basic multiple choice Understanding

Which of the following best describes the organisms in the kingdom Protista?

They are all autotrophic

They can be unicellular or multicellular

Correct

They are exclusively pathogenic

They are only aquatic organisms

Explanation

Organisms in the kingdom Protista can be either unicellular or multicellular, and may be found in various environments.

Question 2

Assertion reason Analyzing

Assertion (A): Kingdom Protista is comprised of unicellular organisms. Reason (R): Many protists are eukaryotic and have complex cellular structures.

Both A and R are true, and R is the correct explanation of A

Both A and R are true, but R is NOT the explanation of A

Correct

A is true but R is false

A is false but R is true

Explanation

While it is accurate that kingdom Protista comprises predominantly unicellular organisms, the reason explaining their complexity as eukaryotic does not directly support the assertion that they are unicellular, as protista can also include multicellular forms.

Question 3

True false Understanding

Kingdom Protista includes only multicellular organisms.

True

False

Correct

Explanation

This statement is false because Kingdom Protista includes both unicellular and multicellular organisms. Protists are a diverse group categorized differently from plants, animals, and fungi.

Question 4

True false Understanding

Members of Kingdom Protista are typically eukaryotic organisms.

True

Correct

False

Explanation

This statement is true as Kingdom Protista consists mostly of eukaryotic organisms, which have a defined nucleus and complex cellular structures.

Question 5

True false Understanding

All protists are autotrophic and capable of photosynthesis.

True

False

Correct

Explanation

This statement is false because not all protists are autotrophic. While some, like algae, are capable of photosynthesis, others are heterotrophic and obtain their food by consuming other organisms.

Question 6

Basic multiple choice Remembering

What is the primary classification of organisms in the kingdom Protista?

Multicellular organisms

Prokaryotic organisms

Eukaryotic organisms

Correct

Fungi

Explanation

The kingdom Protista is primarily made up of eukaryotic organisms, which have a nucleus in their cells.

Question 7

Basic multiple choice Remembering

What is one common characteristic of organisms in the kingdom Protista?

They lack a nucleus.

They reproduce only asexually.

They are mainly found in water.

Correct

They are all photosynthetic.

Explanation

Many organisms in the kingdom Protista are aquatic, but they can also be found in soil and other environments.

Question 8

Basic multiple choice Remembering

Which of the following types of organisms is NOT included in the kingdom Protista?

Algae

Slime molds

Bacteria

Correct

Protozoa

Explanation

Bacteria are prokaryotic and are not classified under the kingdom Protista, which consists of eukaryotic organisms.

Question 9

Complex multiple choice Understanding

Imagine you are studying the Kingdom Protista and discover a newly identified organism that exhibits both plant-like and animal-like characteristics. Which of the following characteristics would best classify this organism within the Kingdom Protista? Consider the distinct features that separate protists from both plants and animals.

It performs photosynthesis but does not have true tissues.

Correct

It has a fixed structure and forms roots like a plant.

It reproduces only sexually, similar to many animals.

It has complex organs for respiration like higher animals.

Explanation

The correct analysis involves recognizing that protists can exhibit characteristics of both plants and animals but lack the complex tissue structure that defines true plants and animals. The organism performs photosynthesis, characteristic of plant-like protists, but its lack of true tissues keeps it in the protist classification. The other options misinterpret the basic biological classification of protists by applying features more typical of plants or animals.

Question 10

Complex multiple choice Analyzing

In a laboratory experiment, a student observes a water sample and identifies a motile single-celled organism that has a nucleus and is capable of photosynthesis. How can this organism be classified within the Kingdom Protista and what implications does its motility have for its ecological role?

It is classified as a protozoan, and its motility helps it evade predators.

It is classified as an algae, and its motility allows for greater access to light and nutrients.

Correct

It is a fungus-like protist, and its motility is irrelevant to its function.

It should be classified as a higher plant given its ability to photosynthesize.

Explanation

The correct answer classifies the organism as an algae, which are photosynthetic protists. Its motility is advantageous as it enhances its ability to find light and nutrients in the aquatic environment. The other options incorrectly classify the organism or misinterpret the role of motility in its ecological context.
