The defferent between a plant animal and a protist,e.g mango tree plant

Classification
When classifying eukaryotic organisms as plants or protists, it is important to note that plants belong to the Kingdom Plantae. Protists do not form a single kingdom because they did not evolve from a common ancestor. In fact, the spectrum of species known as protists are so varied that some have no more in common with one another than they do with plants.[i] To demonstrate this diversity, consider the fact that the nuclear genome sizes in plants vary by a factor of 1000, while the protista genomes differ up to 300,000-fold in s
Complexity
Nuclear DNA strands in plant cells have higher complexity than those in protists. This is because of the presence of genes that give plant cells the ability to differentiate into specific types according to structure and function. Totipotency leads to the formation of specialized tissues, and thus plants can develop into more complex organisms than protists.
In fact, unlike protists, all plants are multicellular. Some protists are unicellular, while some live in colonies of independent cells that communicate and cooperate tasks such as feeding and movement. These colonies are unique to the protist group. Still other protists, such as seaweed, are multicellular and even reach relatively large sizes.[iii]
Nutrition
Plants are primary producers; they are autotrophs that produce food from inorganic molecules. There are no parasitic plants that rely on other plants for nutrients. Some protists, such as algae, are autotrophs that carry out the photosynthetic process in a similar manner, using chloroplasts. However, other protists obtain nutrients in the form of organic molecules and are thus known as heterotrophs or consumers.
A group of protists known as ‘protozoans’ includes several predator and parasite species, which feed on bacteria and other protists. There are some protists known to cause diseases in humans and animals. Still other protists, such as slime molds, are similar to fungi and act as decomposers.
Respiration
Plants require oxygen for the process of cellular respiration. Here protists differ. While some protists are also aerobes, certain protist species are facultative anaerobes, capable of breaking down carbohydrates without the presence of oxygen. There are even obligate anaerobic protist species found in mud and animal digestive tracts. Some plant tissues may have facultative aerobic adaptations.
