Some protoctista have cell walls made of various materials, like cellulose or silica, while others do not have cell walls. The presence or absence of cell walls in protoctista can vary depending on the specific species.

Kingdom Protoctista is difficult to classify because it consists of diverse organisms with unique characteristics that don't fit neatly into other kingdoms. They are grouped based on mostly on their mode of nutrition, locomotion, and reproduction. For example, Protozoa: Unicellular organisms that primarily obtain nutrients through phagocytosis, such as Amoeba. Algae: Photosynthetic protists that can be unicellular or multicellular, like Chlamydomonas. Slime molds: Protists that exhibit characteristics of both fungi and amoebas, such as Physarum polycephalum.
Some examples of phenols include phenol itself (hydroxybenzene), cresol, guaiacol, and catechol. These compounds contain a hydroxyl group attached to a benzene ring.

Protoctista and prokaryotes both lack a true nucleus and membrane-bound organelles. They are both unicellular organisms, although some protoctista may be multicellular. Additionally, they can both be found in various environments and play important roles in ecosystems.

Yes
Protoctista are eukaryotic, meaning they have a true nucleus. Monera are prokaryotic, meaning they have no nucleus.
The kingdom Protista (also known as Protoctista) includes organisms such as Protozoa, Algae and Fungus.

Protoctista is an outdated biological kingdom that encompassed a wide variety of eukaryotic organisms that did not fit into the plant, animal, or fungi kingdoms. It is no longer considered a valid taxonomic group due to advancements in molecular biology and the understanding of phylogenetic relationships among eukaryotes.

The term Protoctista is an outdated kingdom classification that encompassed various eukaryotic organisms that didn't fit neatly into other kingdoms such as animals, plants, or fungi. It has since been replaced by more specific and accurate classifications based on genetic and evolutionary relationships.
