Which of these kingdoms contains unicellular animals?

  1. Eubacteria

  2. Archaebacteria

  3. Fungi

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

The kingdom Protista includes diverse forms of predominantly water-dwelling, eukaryotic unicellular micro-organisms. Some of these organisms are animal-like(protozoan), others resemble plants (algal protists), and others demonstrate the characters of fungi. In kingdom Protista, all organism are unicellular during most phases of their life cycle or are colonial. Thus option D is the correct answer.

An organism without membrane-bound organelles belongs to

  1. Monera

  2. Protista

  3. Fungi

  4. Plantae

  5. Animalia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Kingdom protists, Fungi, Plantae, and Animalia belong to domain eukarya and include only eukaryotic organisms. Kingdom monera includes unicellular prokaryotic organisms that lack a well-defined nucleus and other membrane-bound organelles.Thus, the correct answer is option A.

George Bentham and J.D. Hooker divided dicots into

  1. 3 divisions

  2. 3 sub-divisions

  3. 2 sub-kingdoms

  4. 3 sub classes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Bentham and Hooker divided the Angiospermae into two classes: Dicotyledons and Monocotyledons and in between this they have placed Gymnosperms. Dicotyledons is again divided into three subclasses. They are Polypetalae,  Gamopetale and Monochlamydeae. These sub classes are again divided into series. Series is again divided into order or cohort and order into family. So, the correct answer is '3  sub classes'.

  2. Fungi, Monera and Protista

  3. Protista, Plantae and Animalia

  4. Plantae, Monera and Fungi
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Decomposition is primarily performed by fungi, bacteria (found in Monera), and some protists. While the question asks for a set, these three groups contain the primary decomposers in ecosystems.
