3,829 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.

Diversity in Living Organisms Questions

Multiple choice

Fungi are like plants in many ways except they...

  1. Do not grow upward out of the soil

  2. Do not have eukaryotic cells

  3. Do not have cellulose

  4. Cannot make there own food
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fungi are heterotrophs that cannot produce their own food through photosynthesis, unlike plants. They absorb nutrients from organic matter in their environment, which is a key difference from autotrophic plants.

  1. water

  2. ground

  3. trees

Multiple choice

Hibernation occurs when:

  1. Geese fly to warmer climates in the winter.

  2. Bats decrease activity & breathing rate during cool seasons.

  3. Turtles form an attachment to a beach.

  4. A cat's learned behaviors are rewarded with treats.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hibernation is a state of reduced metabolic activity, such as lower heart and breathing rates, that allows animals to survive periods of cold or food scarcity.

Multiple choice

Sarcodines means of locomotion is _.

  1. cilia

  2. flagella

  3. pseudopods

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

Sarcodines, such as amoebas, move by extending temporary projections of their cytoplasm known as pseudopods. These are often called false feet.

Multiple choice

Protozoans that live on or in a host are _.

  1. sarcodines

  2. ciliates

  3. flagellates

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

Parasites are organisms that live on or inside a host organism, deriving nutrients at the host's expense. Many protozoans are classified as parasites.

Multiple choice

Protozoans with cilia are called _.

  1. sarcodines

  2. ciliates

  3. flagellates

  4. parasites
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia, which they use for movement and feeding.

Multiple choice

Protozoans with flagella are called _.

  1. sarcodines

  2. ciliates

  3. flagellates

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

Flagellates are protozoans that possess one or more whip-like appendages called flagella, which are used for locomotion.

Multiple choice

Protozoans with pseudopods are called _.

  1. sarcodines

  2. ciliates

  3. flagellates

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

Sarcodines are a group of protozoans that move and feed using pseudopods. The most well-known example is the amoeba.

Multiple choice

Plant-like protists are called _.

  1. protozoans

  2. fungi

  3. algae

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

Algae are photosynthetic, plant-like protists. They contain chlorophyll and produce their own food, similar to plants.

Multiple choice

Animal-like protists are called _.

  1. protozoans

  2. fungi

  3. algae

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