What is protoctista?
Protoctista is an outdated biological kingdom that encompassed a wide variety of eukaryotic organisms that did not fit into the plant, animal, or fungi kingdoms.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.
What do protoctista have in common with prokaryotes?
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.
To Which kingdom do fungi belong to?
it waz first in the kingdom protoctista but now in kingdom fugus
How do protoctista detect environmental changes?
Protoctista can detect environmental changes through various mechanisms such as sensing chemical cues in their surroundings, responding to changes in light intensity, or detecting variations in temperature and pH. These organisms may also rely on specialized sensors and receptors on their cell surface to perceive changes in their environment.
What are thallophytes?
Thallophyta are plants having thalloid plant body. Generally representatives of Algae and Fungi are called thallophytes. The official definition of the word thallophytes is "a plant that consists of a thallus."
Is the kingdom protista a legitimate taxonomic group?
No, the kingdom Protista is no longer considered a legitimate taxonomic group. It is a polyphyletic group, meaning it does not include all descendants of a common ancestor. The organisms once classified in Protista have been reclassified into other kingdoms such as Plantae, Animalia, and Fungi.
Are snakes and lizards polyphyletic?
yes they r polyphyletic

Are echinoderms monophyletic or polyphyletic?
monophyletic
Why are animals monophyletic?
Because they're descended from a common ancestor and the classified group includes all animals. The other kinds, para- and polyphyletic groups, are classified groups that have multiple ancestors (poly) or are a single group but with parts excluded (para). Carnivorous plants are polyphyletic, as they include many different genera, and reptiles are paraphyletic, because it excludes birds which are technically still reptiles.
Are protists monophyletic polyphyletic or paraphyletic?
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
Is protoctista a living thing?
Yes
Does a protoctista cell have a nucleus?
yes
How is microorganism of Monera kingdom different from Protoctista kingdom?
Protoctista are eukaryotic, meaning they have a true nucleus. Monera are prokaryotic, meaning they have no nucleus.
Why is the kingdom animalia polyphyletic and not monophyletic?
Its not polyphyletic, its monophyletic. There are no points where members stop being animals. Many mistake Porifera (sponges) as an exception, but they are animals too.
What genus is the toad?
'Toads' are actually not a scientifically valid group; they are simply a common name for a number of polyphyletic, warty skinned, mainly terrestrial amphibians in the order Anura.
Common name of kingdom protista?
The kingdom Protista (also known as Protoctista) includes organisms such as Protozoa, Algae and Fungus.
