What is the main difference between protists and bacteria quizlet?

What is the main difference between protists and bacteria quizlet?

the major difference is that protists are eukaryotes while bacteria and archea are both prokaryotes. this means that prokaryotes do not have a nucleus, and contain circular DNA.

What does a protist have that a bacteria doesn t?

Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won’t be.

Which answer best explains the difference between protist and bacteria?

Which answer best explains the difference between protists and bacteria? A. Bacteria are prokaryotes and protists are eukaryotes. Bacteria have cytoplasm while protists do not.

How are protists different from bacteria and archaea quizlet?

How are protists different from bacteria and archaea? They are at least ten times larger. They are eukaryotes. They consist of both single- and multi-celled organisms.

What are two major differences between prokaryotic bacterial and eukaryotic protist cells?

Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Do protists eat bacteria?

Protist Nutrition Ingestive protists ingest, or engulf, bacteria and other small particles. They extend their cell wall and cell membrane around the food item, forming a food vacuole.

Can plant-like protists move?

Zooflagellates are a third type of protists. They are animal-like and move by using flagella. Flagella are whip-like structures that spin quickly, working like a boat’s propeller to move the organism through water. Plant-like protists are commonly called algae.

Why do protists and bacteria benefit us?

Why? 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. All protists make up a huge part of the food chain.

What are some characteristics of protists?

Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles….Characteristics of Protists

• They are eukaryotic, which means they have a nucleus.
• Most have mitochondria.
• They can be parasites.
• They all prefer aquatic or moist environments.

What’s the difference between protists and bacteria cells?

According to common biological classification, protists are classified under Kingdom Protista, while Bacteria are classified under Kingdom Monera. Unlike the cells of other organisms (plants and animals), protists and bacteria cells have very low level of cell differentiation.

Where are protists found in the human body?

They comprise a major part of the population in the environment. Protists are found only in moist surroundings. Although bacteria are notoriously known to cause diseases in humans, they are also beneficial in many ways. They maintain a healthy balance in the environment.

How are bacteria similar to plants and fungi?

They have organisms which show characteristics similar to animals, plants or fungi. Thus, they further divided into 3 categories i.e. plant-like Protists, animal-like Protists or fungi-like Protists. Bacteria are single-celled organisms and their cell structure is very simple. There is no nucleus which is the chief controller of a cell.

Which is the oldest organism on Earth bacteria or protists?

Bacteria are the oldest organisms known to exist on earth. They belong to the oldest Kingdom Monera while Protists are classified as Kingdom Protista. They have organisms which show characteristics similar to animals, plants or fungi.
