Diversity in Living Organisms

3,323 Questions

The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

  2. the bald eagle and the gray hawk live in the same place

  3. the bald eagle is more like the gray hawk than the osprey

  4. the bald eagle and the osprey eat the same food

C Correct answer
Explanation

Taxonomy groups organisms by shared characteristics. Being in the same family indicates a closer evolutionary relationship than being in the same order but different families.

Multiple choice

Which is a question a scientist might ask to classify an organism into the correct kingdom?

  1. Can the organism breed with similar organisms?

  2. Does the organism have one cell or many cells?

  3. Does the organism have a backbone?

  4. Are there other organisms that are the same?
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Kingdoms are broad categories often distinguished by cellular organization (unicellular vs multicellular) and metabolic processes. Whether an organism is single-celled or multicellular is a primary classification question.

Multiple choice

Bacterial cells are prokaryotic this means they lack

  1. Genetic material

  2. A cell membrane

  3. An organized nucleus

  4. Cytoplasm
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Prokaryotic cells, such as bacteria, are defined by the absence of a membrane-bound nucleus and other membrane-bound organelles.

Multiple choice

Many organisms are microscopic. What does this mean?

  1. They are GIANT!

  2. They are all clear and without color.

  3. They can not be seen with just your eye.

  4. They all have microscopes.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Microscopic refers to objects that are too small to be seen by the naked eye, requiring a microscope for observation. It does not refer to size in a giant sense or color.

Multiple choice

algae is an example of

  1. fungi

  2. protist

  3. animal

  4. plant

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Algae are eukaryotic organisms that are typically classified within the kingdom Protista. While they perform photosynthesis like plants, they lack the complex tissues found in true plants.

Multiple choice

Mold is an example of

  1. plant

  2. protist

  3. fungi

  4. animal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mold is a type of fungus. Fungi are heterotrophic organisms that absorb nutrients from their environment.

Multiple choice

All of these kingdoms have organelles EXCEPT

  1. animals

  2. plants

  3. protists

  4. monera
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Monera (prokaryotes) are unicellular organisms that lack membrane-bound organelles, such as a nucleus. Animals, plants, and protists are eukaryotes and possess these organelles.

Multiple choice

Bacteria are in this kingdom

  1. fungi

  2. plant

  3. animal

  4. monera
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bacteria are prokaryotic organisms traditionally classified in the kingdom Monera. Modern systems often use the domain Bacteria, but in this context, Monera is the intended answer.

Multiple choice

The simplestest protozoa is

  1. Amoeba

  2. Euglena

  3. Plasmodium

  4. Paramecium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Amoeba is often cited as one of the simplest protozoa due to its simple, unicellular structure and lack of complex organelles compared to others like Paramecium or Euglena.
