How are protists helpful and harmful?

How are protists helpful and harmful?

Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis.

How do protists affect the environment?

Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers. In addition, many protists are parasites of plants and animals and can cause deadly human diseases or destroy valuable crops.

Are plant-like protists good or bad?

Plant-like protists are essential to the ecosystem. They are the base of the marine food chain, and they produce oxygen through photosynthesis for animals to breathe.

What are the disadvantages of protists?

The major negative about protists is that some cause diseases, both in humans and in other organisms. Examples are amoebic dysentery, meningo-encephalitis, malaria, toxoplasmosis, and African sleeping sickness.

What do plant-like protists have in common with plants?

Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Like plants, they contain chlorophyll and make food by photosynthesis.

How do animal like protists harm other living things?

How do “animal-like” protists harm other living things? They cause serious diseases like malaria & African sleeping sickness. the cytoplasm of the cell “streams” into the pseudopod and the rest of the cell follows. When under “stress” paramecia exchange genetic material with other individuals.

What are the advantages of protista?

Protists also provide many benefits to both humans and other organisms. For example, plant-like protists produce almost half of the oxygen found on our planet through the process of photosynthesis. That’s pretty impressive for organisms that are often microscopic in size! Other types of protists act as decomposers.

What are the advantage and disadvantage of fungi?

General Science ADVANTAGE : 1) As food – food like mushrooms and dried yeast which provide us protein and vitamin. 2) In agriculture – likemaking the soil fertile. DISADVANTAGES : 1) human diseases – A no.

How are plant-like protists and animal-like protists different?

Answer: Animal-like protists and plant-like protists are both eukaryotic and live in moist environments. All animal-like protists are unicellular, while plant-like protists can be unicellular, multicellular, or live in colonies. Most animal-like protists can move, while only some plant-like protists can move.

How are plant-like protists affect human health?

Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Click to see full answer

What are the symptoms of the protist Plasmodium?

Malaria is caused by plasmodium, a protist that uses mosquitoes as an intermittent host before infecting humans. Once a human is infected with malaria, common symptoms include fever, chills, sweating, headaches, nausea, vomiting, and body aches.

How are Giardia protists harmful to the human body?

Most cases are fatal, although in a few instances, non-symptomatic carriers have been identified. Giardiasis is caused by giardia protists. Humans consume them by eating or drinking food or water contaminated by fecal material.

How are protists and plants similar to each other?

Plant-like protists are autotrophs. This means that they produce their own food. They perform photosynthesis to produce sugar by using carbon dioxide and water, and the energy from sunlight, just like plants. Unlike plants, however, plant-like protists do not have true stems, roots, or leaves.
