Kingdom Protista is said to be the most diverse kingdom,
because each of its members are so individual from each other
. If an organism does not belong any particular kingdom, it goes into kingdom Protista. This miscellanous grouping causes the organisms in the kingdom to be very different from each other.
Is the kingdom Protista diverse?
Protists are
a diverse collection of organisms
. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.
How do protists demonstrate diversity?
Protists are extremely diverse in terms of
their biological and ecological characteristics
, partly because they are an artificial assemblage of phylogenetically unrelated groups. … Most single-celled protists are motile, but these organisms use diverse structures for transportation.
What kingdom is most diverse?
Members of
the animal kingdom
are found in the most diverse environments in the world.
Does kingdom Protista still exist?
NOTE: The current system of classification for eukaryotes has been changed. In 2005, based on new phylogenetic data the kingdom Protista was split into 5 supergroups. … Protists belong to the Kingdom Protista, which include mostly unicellular organisms that do not fit into the other kingdoms.
What defines the kingdom Protista?
:
any of a diverse taxonomic group and especially a kingdom
(Protista synonym Protoctista) of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi (such as slime molds)
What diseases can protists cause?
Most protist diseases in humans are caused by protozoa. Protozoa make humans sick when they become human parasites. Trypanosoma protozoa cause
Chagas disease
and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.
Do protists need oxygen?
Although
most protists require oxygen
(obligate aerobes), there are some that may or must rely on anaerobic metabolism—for example, parasitic forms inhabiting sites without free oxygen and some bottom-dwelling (benthic) ciliates that live in the sulfide zone of certain marine and freshwater sediments.
How do protists grow and develop?
Slime molds are an example of sexually reproducing protists. They give
off spores
, which grow to the amoeboid form. They are then fertilized and undergo mitosis to form the feeding plasmodium stage. Finally, they mature and eventually give off spores of their own.
Are there 5 or 6 kingdoms?
Living things are
divided into five kingdoms
: animal, plant, fungi, protist and monera. Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.
When biologists say the kingdom Protista is very diverse they mean?
Protists are said to be the most diverse
of all eukaryotic kingdoms
because the organisms in the Protista kingdom are eukaryotic organisms that are not plants, animals, or fungi. You just studied 10 terms!
What makes the Protista kingdom unique?
Protists are eukaryotes, which means their cells have
a nucleus and other membrane-bound organelles
. … These unique organisms can be so different from each other that sometimes Protista is called the “junk drawer” kingdom.
Why is Protista not a kingdom anymore?
Explanation: Because
Protist has many organisms that are related to the other kingdoms of animals, plants, and fungi
. Protists is a word that is know used as a “eukaryote that isn’t a plant, animal, or fungus.”
Is virus a Protista?
Whereas viruses as pathogens of humans and livestock have been intensely studied for a century, much less is known about the majority of viruses – especially those that infect microbes. Protists are
unicellular eukaryotes
and harbor a wide spectrum of viruses, from small RNA viruses to giant DNA viruses.
Why are protist no longer in their own kingdom?
Protista polyphyletic: some protists are more closely related to plants, fungi or animals than they are to other protists;
it was too diverse
, so it no longer a single kingdom.
What best describes the kingdom Protista?
Protists are
eukaryotic organisms that cannot be
classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. … Protists primarily live in water, though some live in moist soil. They can be found almost anywhere on Earth where there is liquid water, even in humans.
