How do protists get oxygen?

Animal like protists use cellular respiration, plant-like protists can use photosynthesis or cellular respiration, and fungi-like protists can use either aerobic or anaerobic respiration. … Insects use a system of spiracles,tracheal tubes on the sides of the body, to supply oxygen for cellular respiration.

What do protists use for energy?

Protists Nutrition That means that protists can obtain food like plants, fungi, or animals do. There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis.

What are the 3 groups of protists?

Lesson SummaryAnimal-like protists are called protozoa. Most consist of a single cell. … Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. … Fungus-like protists are molds. They are absorptive feeders, found on decaying organic matter.

What are the three types of nutrition found in protists?

The major modes of nutrition among protists are autotrophy (involving plastids, photosynthesis, and the organism’s manufacture of its own nutrients from the milieu) and heterotrophy (the taking in of nutrients).

How do protists benefit humans?

Humans use protists for many other reasons: Many protists are also commonly used in medical research. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Other protists are used in scientific studies.
