Viruses that infect plants generally possess single-stranded RNA as their genetic material. In contrast, animal viruses may contain single- or double-stranded RNA or double-stranded DNA.

Fungi may reproduce vegetatively by fragmentation, fission and budding. Spore formation is classified separately as asexual or sexual reproduction depending on the type of spore produced.

The fungal body generally consists of long, slender, thread-like structures called hyphae. The network formed by these hyphae is known as the mycelium.

Whittaker used cell structure, body organisation, mode of nutrition, reproduction and phylogenetic relationships as the principal criteria for his five-kingdom classification.

The plant life cycle has a diploid sporophytic phase and a haploid gametophytic phase that alternate with each other. The duration and independence of these phases vary among different plant groups.

Members of Kingdom Animalia are multicellular, heterotrophic eukaryotes whose cells lack cell walls. They store food reserves as glycogen or fat and generally show holozoic nutrition.

Fungi are heterotrophic organisms, whereas green plants are autotrophic. Their cell walls also differ: fungal walls contain chitin, while plant cell walls are mainly cellulosic. These differences support their placement in separate kingdoms.

The organism is a euglenoid. Euglenoids possess a flexible pellicle and two unequal flagella. They photosynthesise in sunlight but behave as heterotrophs by preying on smaller organisms when sunlight is unavailable.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Five Kingdom Classification and Kingdom Plantae Animalia
The organism belongs to Kingdom Animalia. Animals are multicellular heterotrophs without cell walls, ingest and internally digest food, and store reserve food as glycogen or fat.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Five Kingdom Classification and Kingdom Plantae Animalia
The organism belongs to Kingdom Fungi. Fungi are absorptive heterotrophs, their walls contain chitin and other polysaccharides, and their reserve food is stored as glycogen and oil droplets.

The diploid sporophytic phase and the haploid gametophytic phase alternate in plant life cycles. Their relative duration and dependence vary among different plant groups.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Five Kingdom Classification and Kingdom Plantae Animalia
The organism belongs to Kingdom Animalia. Animals are multicellular heterotrophs without cell walls, obtain food by ingestion and internal digestion, and store reserve food as glycogen or fat.
