Protists are generally single celled organisms grouped under the Protista Family, but recently they have been reconsidered to be a grouping of organisms that have little in common but that they do not fit in elsewhere and while they do have complex organelles, they do not differentiate tissues. They can have various trophic modes, motility, cell coverings, and life cycles.

A eukaryotic organism that lacks complex organ systems?

An example of a eukaryotic organism that lacks complex organ systems is a protist like an amoeba. Protists are single-celled organisms that do not have specialized tissues or organs like multicellular organisms. Instead, they rely on various organelles within their cell to carry out essential functions.


Why is volvox considered a protist rather than a metazoan animal?

Volvox is considered a protist because it is a colony of individual cells working together as a single organism. Each cell within the colony retains its own identity and functions, unlike in metazoan animals where cells are specialized and cannot survive independently. Additionally, Volvox lacks the complex tissue organization and body plan characteristic of metazoans.

What criteria could you use to determine the most primitive protist?

The most "primitive" protist in the Kingdom Protista would be the more ancestral protists. One major group of protists called the Excavates (which include the Diplomonads and the Parabasalids) are considered by some scientists as the most "primitive" because it lacks a mitochondria while other protists have mitochondria.


What division lacks a well differentiated body design?

The division that lacks a well-differentiated body design is often referred to as the division of "primitive" or "simplistic" organisms, such as certain members of the phylum Porifera (sponges). Sponges are characterized by their simple structure, lacking true tissues and organs, and they rely on a porous body plan for filter feeding. This simplicity distinguishes them from more complex multicellular organisms that have specialized structures and functions.

Is a sponge an organism?

No, a sponge is not considered an organism in the traditional sense because it lacks complex organ systems and does not exhibit characteristics of living organisms like movement or the ability to consume nutrients. Sponges are classified as multicellular filter feeders belonging to the animal kingdom.


Is it true that the relationship between drug and alcohol use and crime is complex and lacks a cohesive explanation?

Yes, the relationship between drug and alcohol use and crime is complex, and thus the problem lacks a cohesive explanation. There are many factors involved, but no one factor completely explains the relationship between drug/alcohol use and crime.


Is an amoeba a eucaryotic cell?

Nope it prokaryotic because it's a single celled organism. It lacks complex internal cellular structure. Hope this helps


What are the disadvantages of MINIX?

MINIX, while a great educational tool for understanding operating system concepts, has several disadvantages. Its performance is generally inferior to modern operating systems due to its microkernel architecture, which can lead to inefficiencies in handling system calls. Additionally, MINIX lacks the extensive hardware support and software ecosystem found in more popular systems like Linux, making it less practical for real-world applications. Furthermore, its focus on simplicity can limit advanced features that are present in more complex operating systems.
