This means that they have the property of cells with nuclei, but cannot be categorised as an animal plant of fungus. Although most Protista species are identified as unicellular, there is a few that can be multicellular protists species such as kelp Because Kingdom Protista present themselves in soil or area with moisture, the are usually known to be aquatic. They may occur to be autotrophic or heterotrophic in nature. If they are classified as autotrophic organisms, they can create their own food and survive. But if they are classified as heterotrophic organisms, they have to derive nutrition from other organisms such as plants or animals to survive. Kingdom Protista is associated as asexual, this means that they reproduce with without sexual feelings, but with freelining’s of stress instead. Kingdom Protista use cilia and flagella for locomotion, but there are only a few Protista organisms with pseudopodia that can insure movement. Kingdom Fungi Fungi are eukaryotic, non-vascular, non-motile (not exhibiting or capable of movement and heterotrophic organism. Kingdom fungi plays a critical role in the ecosystem because some fungi are responsible for the decomposition of dead matter. With this decomposition proses, they provide nutrition for other plans so that the ecosystem can continue to prosper. Because Fungi lacks chlorophyll, they cannot perform the process of photosynthesis. Fungi has the ability to store their food as a form of starch. Kingdom Fungi may occur to be unicellular or filamentous. Fungi are known to reproduce asexual or sexual, but they don’t have an embryonic stage. They develop using spores. Although some Fungi (like mushrooms) are a food source for animals, some are known to be parasitic and can infect the host. Kingdom Plantae Kingdom Plantae represents all plants. They are eukaryotic, multicellular and autotrophic organisms with a sufficient sell wall.
