ii. Bacteria and cyanobacteria were placed in plant kingdom
iii. Uniellular or simple multicellular eukaryotes wrongly placed in kingdom plantae and animalia.
iv. Fungi are wrongly placed in kingdom plantae
Ans 2: Three Kingdom:
i. It includes three kingdoms plantae, Animalia, Protista
ii. Euglena was placed in kingdom protista.
iii. Multicellular microscopic organismsm were spearated from uncellular microscopic organisms.
iv. Fungi were placed in kingdom plantae
Ans 3: Five Kingdom:
i. It includes five kingdoms Monera, protista, Fungi, plantae and Aimals
ii. Bacteria and cyanobacteria are placed in kingdom Moneara
iii. Unicellular or simple multicellular eukaryotes placed in kingdom Protista
