What is the size of Protista?

Answer 1

Protozoa can be 0.01 mm to 1.0 mm in length.

*The exact classification and definition of Protozoa has been changing, and should not be confused with Protists. Traditional classification states Protists as one of the five kingdoms; this kingdom is then broken down into the two subkingdoms of Protozoa and Algae. Modern classification generally uses the terms Protozoa and Algae as convenient ways to refer to an organism's characteristics rather than official taxonomic categories.

-Protozoa includes heterotrophic organisms (animal-like protists) that are unicellular and usually mobile by their own means. Good examples include Amoebas, Paramecia, and Trypanosomes.

-Algae includes photosynthetic Protists (plant-like or autotrophic protists), they can be multi-celled or single-celled. Multi-cellular structures can reach over 300 feet (100 meters) in length; a good example would be kelp.

Answer 2

Protista is a varied kingdom consisting of unicellular, colonial, and multicellular organisms. It is not characterized by a specific size, as it can range from microscopic single-celled organisms to large multicellular algae.

Answer 3

he largest known protist is the xenophyophore Syringammina fragilissima. Xenophyophores are one-celled, multinucleate creatures found at depths of 800 to 6000 meters on the ocean floor. A characteristic feature of xenophyophores is that they construct a sort of artificial exoskeleton by gluing together particles of sediment and the microscopic shells of foraminifera. (The name "xenophyophore" is Greek for "foreign body bearer.") These agglomerations are called tests.

In the case of S. fragilissima, the test is a network of tubes. The tests are extremely fragile, and specimens are rarely recovered.

In 2006 in an area called the Darwin Mounds, northwest of Scotland, researchers discovered specimens of Syringammina fragilissima with tests as large as 20 centimeters in diameter.

Answer 4

Protists are a very diverse group and include organisms that range in size from single cells to complex structures more than 100 meters long.

Answer 5

The protists are bigger than big but not that big ok big boy?

Answer 6

I don't know the exact size but a protist is much larger than viruses and bacteria.

Answer 7

The average size of a Protista cell is between 10 and 100 micro meters. A Protista cell is a classification of organisms that include both single and multicellular organisms.

Answer 8

some 10-15
