What are plant-like protists collectively called?

  1. Protozoans

  2. Algae

  3. Fungi

  4. Pseudopodia
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The five kingdom classification was proposed by R. H. Whittaker which classifies all the living organisms into these five kingdoms. The Protista is a kingdom of simple single-celled eukaryotic organisms. They have well-developed cell organelles on the basis of which they have been classified into plant and animals like protists. The plant-like protists have chlorophyll, can perform photosynthesis and are collectively known as protists.
Thus, the correct answer is option B.

A group of biology students were studying about the algae. They prepared a sample slide using a water sample drawn from a puddle. While observing the sample under microscope, they noted that those were living in the colony and the colony was coated with a jelly-like substance. Using these hints identify the organism.

  1. Ulva

  2. Sargassum

  3. Volvox

  4. Diatom

C Correct answer
Explanation

Volvox is a freshwater green alga. It is found in multicellular colonies. These colonies are known as "coenobium". They also move together in colonies.

So, in this case, option C " Volvox" is the correct answer.

Colourless, unicellular, cell wall bound, spherical or rod-shaped micro-organism lacking organized nucleus is called as

  1. Mycoplasma

  2. Virus

  3. Bacteria

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

According to five kingdom classification, bacteria are placed in kingdom monera. Organisms of kingdom monera are single celled and they have cell wall made up of peptidoglycans. Their nuclear membrane is absent, have single chromosome and do not have membrane bound cell organelles. DNA is double stranded and suspended in cytoplasm (called nucleoid).

Which of the following kingdom includes Amoeba?

  1. Porifera

  2. Protozoa

  3. Platyhelminthes

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The kingdom protozoa include single-celled eukaryotic organisms. Amoeba is a single-celled eukaryotic organism that has no definite shape and that moves by means of pseudopodia. As amoeba is single-celled eukaryotic organism it is placed is kingdom Protozoa.
So, the correct answer is 'Protozoa'.
