Plasmodiophores are pathogenic for a wide range of organisms, but mainly green plants.The more commonly recognized are agents of plant diseases such as clubroot, powdery scab and crook root of watercress, [6] or vectors for viruses that infect beets, peanut, monocots and potatoes, such as the potato mop-top virus or the beet necrotic yellow vein virus.
Myzozoa [1] is a grouping of specific phyla within Alveolata, [2] [3] that either feed through myzocytosis, or were ancestrally capable of feeding through myzocytosis. [1] Many protist orders are included within Myzozoa. [1] [4] It is sometimes described as a phylum, containing the major subphyla Dinozoa and Apicomplexa, plus minor subphyla. [5]
The taxon 'Protozoa' fails to meet these standards, so grouping protozoa with animals, and treating them as closely related, became no longer justifiable. The term continues to be used in a loose way to describe single-celled protists (that is, eukaryotes that are not animals, plants , or fungi ) that feed by heterotrophy . [ 9 ]
For example, protozoa can help maintain the quality of the soil by grazing on soil bacteria. Through their grazing, the protozoa can help maintain populations of bacteria, allowing the bacteria to more efficiently decompose dead organic material which will improve the fertility of the soil .
Haemoproteus is a genus of parasitic protozoa that belong to the Apicomplexa phyla. The megaloschizont cells measured 50 to 100 micrometers. The megaloschizont cells measured 50 to 100 micrometers. The merozoites inside the megaloschizonts were less than 1 micrometer in diameter.
The initial targets of Cavalier-Smith's classification, the protozoa were classified as members of the animal kingdom, [12] and many algae were regarded as part of the plant kingdom. With growing awareness that the animals and plants embraced unrelated taxa, the use of the two kingdom system was rejected by specialists.
Protozoa from "Zenon: Girl of the 21st Century" was basically the the coolest rockstar to come from Outer Space. He was a heartthrob to Zenon and girls and boys everywhere, and we all just wanted ...
Myxomycota, now considered a synonym of Myxogastria, comes from the Ancient Greek words μύξα myxa, which means "mucus", and μύκης mykes, which means "fungus".The name Myxogastria was introduced in 1970 by Lindsay Shepherd Olive to describe the family Myxogastridae, which was introduced in 1899 by Thomas Huston Macbride.
