Question

Pick up the wrong statement
A. The nuclear membrane is present in Monera
B. The cell wall is absent in Animalia
C. Protista have photosynthetic and heterotrophic mode of nutrition
D. Some fungi are edible

Answer 1

Hint: Kingdom Monera is prokaryotic and organisms of this kingdom lack a true nucleus, and membrane-bound organelles. The cell wall is the structural wall surrounding the cell and provides rigidity to the cell. Kingdom Protista comprises eukaryotic organisms and Kingdom Fungi also include eukaryotic organisms such as yeasts and moulds.

Complete answer: Kingdom Monera includes bacteria and cyanobacteria and organisms that belong to this kingdom are prokaryotic and they do not have membrane-bound organelles such as a true nucleus and the nuclear membrane. Organisms belonging to the kingdom Monera include unicellular organisms. The peptidoglycan cell wall is present. Autotrophic, heterotrophic, parasitic and saprophytic are the modes of nutrition.
a) Plants have a cell wall made up of cellulose but animals do not have a cell wall and chlorophyll. Animals have heterotrophic mode of nutrition. Kingdom Animalia has several subphylas.
c) Organisms belonging to the kingdom Protista have two modes of nutrition, viz. autotrophic: They produce their food through photosynthesis or chemosynthesis and heterotrophic mode of nutrition. Autotrophic protists are red, brown and green algae, diatoms, etc. Heterotrophic protists are Amoeba, Paramecium, Sporozoa, etc.
d) Kingdom fungi have both edible and poisonous species, for example, mushrooms are edible. Other species belonging to the kingdom Fungi are Yeasts, Moulds, Truffles, etc. Fungi have a filamentous structure with a cell wall made up of chitin. Reproduction is mainly by the formation of spores.
Hence, the correct answer is option A.

Note: The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866. Subsequently, the phylum was elevated to the rank of the kingdom in 1925 by Édouard Chatton.
