Do protists help humans

Answer 1

Protists are tiny organisms in the Domain of Eukarya. Historically they were part of the Kingdom of Protista, but this is no longer the case. Protists are incredibly diverse, and there is little to bind them together as a grouping, except for the simplicity of their structure. Protists have either one cell, or else have multiple cells without any specialized tissues. This is what distinguishes protists from other eukaryotes like animals, plants, and fungi. Historically, protists were divided into three groups, based on which of the major Kingdoms they were most similar to. Although this particular classification is no longer formally used, many people still use them to describe protists. The protozoa are the protists which have the most in common with animals. The protophyta have more in common with plants and slime molds are most similar to fungi. Some protists are motile, able to move by using flagella, pseudopodia, or cilia, while others are unable to move. They may live on their own by absorbing energy from sunlight, or they may live symbiotically with a host organism. In some cases, protists may engage in a mutual symbiotic relationship, where the protists gain energy from the host, but perform some beneficial service in return, but often they are parasitic, simply leeching energy off of the host. Protists play fundamental roles in the ecosystems of the world. As such, many protists are quite beneficial to humans. Others, however, are harmful to humans. Protists such as apicomplexa and kinetoplastids cause any number of diseases that afflict human beings, such as malaria, and some protists, such as the amoeba, can cause serious illness when their population gets out of control in the body. The protophyta, or algae, are the protists which play the most beneficial role for humans. Many of the protophyta form the basis of the food chain which drives the engine of life on the planet. The algae create food for other organisms, growing and expanding by absorbing the light of the sun through photosynthesis and serving as food for the lowest-level animal organisms, which in turn serve as food all the way up the food chain. The vast majority of the plankton in the ocean consists of various protists. These algae often look like plants, but they differ in a number of key ways: they have no leaves, no stems, no roots, and no distinct helper parts. In spite of this, they may reach large sizes not usually associated with simple oranisms. Protophyta not only create food, but they also respirate oxygen, making them crucial for sustaining animal life on the planet. In fact, algae generate about half of the oxygen generated by photosynthesis on the planet. It is beyond doubt that the protists play one of the most important roles in sustaining human health on the planet. Without the protists, the ocean’s food chain would collapse, and in turn the food chain as a whole would crumble, and at the same time oxygen would be reduced drastically.
