Answer
i. All organisms are multicellular, eukaryotes with heterotrophic mode of nutrition.
ii.
iii. Linnaeus used artificial system kingdom of classification.
Drawbacks of Linnaeus two kingdom classification:
• Linnaeus developed a Two Kingdom system of classification with Plantae and Animalia kingdoms.
• This system did not distinguish between eukaryotes and prokaryotes, unicellular and multicellular organisms, photosynthetic (green algae) and non-photosynthetic (fungi) organisms.
OR
No, Fungi-Autotrophic (Photosynthetic) and Heterotrophic is not correct match. The walls of the fungi were made of chitin, whereas the green plants had a cellulose cell wall.
ii.
| Prokaryotic cell | Eukaryotic cell |
| Genetic material is not enclosed in a nuclear envelope and is present suspended in the cytoplasm in a region called nucleoid. | Genetic material is enclosed within the nucleus by a nuclear envelope and is not present in direc contact with cytoplasm. |
| Cell wall is made up of peptidoglycan. | Cell wall is made up of chitin in fungi and cellulose in plants. |
| Nucleolus is absent. | Nucleolus is present. |

There are thousands of different eubacteria or 'true bacteria'. They are characterized by the presence of a rigid cell wall, and if motile, a flagellum. The cyanobacteria (also referred to as blue-green algae) have chlorophyll a similar to green plants and are photosynthetic autotrophs. The cyanobacteria are unicellular, colonial or filamentous, freshwater/marine or terrestrial algae. The colonies are generally surrounded by gelatinous sheath. They often form blooms in polluted water bodies. Some of these organisms can fix atmospheric nitrogen in specialized cells called heterocysts, e.g., Nostoc and Anabaena. Chemosynthetic autotrophic bacteria oxidise various inorganic substances such as nitrates, nitrites and ammonia and use the released energy for their ATP production. They play a great role in recycling nutrients like nitrogen, phosphorous. iron and Sulphur.

The fungi constitute a unique kingdom of heterotrophic organisms. They show a great diversity in morphology
and habitat. Fungi are cosmopolitan and occur in air, water, soil, and on animals and plants. They prefer to grow in warm and humid places. Most fungi are heterotrophic and absorb soluble organic matter from dead substrates and hence are called saprophytes. When a fungus reproduces sexually, two haploid hyphae of compatible mating types come together and fuse. In some fungi, the fusion of two haploid cells immediately results in diploid cells (2n). The fungiform fruiting bodies in which reduction division occurs, leading to the formation of haploid spores. Symbionts - in association with algae as lichens and with roots of higher plants as mycorrhiza. Three types of reproduction occur in fungi
