Protists

Protist Kingdom

Cell Type: Protists are eukaryotic. Most have one cell, but some have many cells, such as algae. Some are heterotrophic and some are autotrophic


Cell Structure: Cells have a membrane around the nucleus


DNA and RNA characteristics: They keep their DNA inside the nucleus and is unique to the protist kingdom.


Mode of movement: Most of the organisms in the Protista kingdom move by either flagella or cilia, but some move because of the change in pressure in their cells.


Reproduction: Most types of Protista reproduce asexually, but there are some types sexually, such as types of algae. Although most of them reproduce by binary division.


Habitat: Most Protista can be found in ponds, wet patches of moss and moist soil, but there is the potential that they can be found in any moist place.

How they gain nutrition or energy: Fungus like protists absorb food from their surroundings, plant like protists and photosynthetic and animal like protists ingest food particles


Interesting facts: The organisms in the Protista kingdom don’t share many similar characteristics. Lots of them are just in this kingdom because they don’t fit into any other kingdom properly
