Is Chlamydomonas a plant or animal?
So, Chlamydomonas is a plant-animal, still related to the last common ancestor of the two kingdoms. The green yeast has been a denizen of the laboratory for decades. It is easy to grow in liquid cultures and has fascinating morphology and behaviors.
What is the purpose of protists?
Protists produce almost one-half of the oxygen on the planet through photosynthesis, decompose and recycle nutrients that humans need to live, and make up a huge part of the food chain. Humans use protists for many other reasons: Many protists are also commonly used in medical research.
Where can protists be found?
Most protists can be found in moist and wet areas. They can also be found in tree trunks and other organisms.
What do all protists have in common?
What do all protists have in common? They have a nucleus and other complex organelles. They lack some characteristics that prevent them from being classified as plants,animals, or fungi.
What are the similarities between protists and bacteria?
Both bacteria and protists have cell membranes made of chemicals called phospholipids. A phospholipid in a bacterium or a protist has a water-soluble group at one end and a water-insoluble tail at the other, so the cell membranes of bacteria and protists are constructed from a bilayer of phospholipids.
What is the main difference between bacteria and protists?
Protists have a highly evolved and well defined cell structure in comparison to Bacteria. Protists are only found in moist surroundings, while bacteria are found everywhere. Bacteria are single celled while protists can be single celled or multicellular.
Can all protists survive in any environment?
Most protists are aquatic organisms. They need a moist environment to survive and are found in places where there is enough water for them, such as marshes, puddles, damp soil, lakes, and the ocean. Some protists are free-living organisms and others are symbionts, living inside or on other organisms, including humans.
How does protists respond to the environment?
Animal like Protists Respond to stimuli (changes, Reactions) by covering them selves when conditions become not right , ( That means no oxygen, water food or any other supplies can come in.) This also means they can avoid harmful chemicals from the environment.
How can protist infections be prevented?
Infection can only be prevented by stopping individuals from being bitten. People sleep under mosquito nets and wear insect repellent to avoid bites. Antimalarial drugs are also taken, which treat the symptoms and can prevent infection.
How are protists helpful to humans?
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.
