Summary Introduction
To review:
To identify the group of protists and the reason why they are referred as “animal like protists”.
Introduction:
Protists are diverse group of eukaryotic organisms. They are unicellular, some are colonial or multicellular. They do not have specialized tissue organization. They live in any environment which contains water.

Students have asked these similar questions
The internal structure of many protists is much more complexthan that of cells of multicellular organisms. Does thismean that the protist is engaged in more complex activitiesthan the multicellular organism is? If not, why are protistancells more complicated?
1. How is designated the ancestral protist lineage that gives origin to the metazoans?
2. Layout that protist lineage (inform the names of the structures)
3. Wich big philo of metazoa is most related to this protist lineage?
4. What is the main sinapomorphy of this meathozary group?
5. How can the relationship be morphologically proven to the ancestral protist lineage?
6. The feeding of the basal metazoan has characteristics considered plesiomorphic. Indicate the food habit and digestion process of the basal metazoan
(I'm sorry, i don't speak english very well)
A parasitic protist has been isolated and is on a microscope slide. How could you
determine whether it belongs to te Apicomplexans or Excavata supergroup?
Look for spores which would indicate Excavata
Look for flagella which would indicate Excavata
There is no way to distinguish based on structural characteristics.
Look for flagella which would indicate Apicomplexans

You note the organism appears to be “eating” the smaller microorganism. Chemical analysis of test tube 2 indicates the presence of a chemical that is toxic to fish and humans. In test tube 3, you detect the presence of substantial amounts of silica. Microscopic analysis of organisms in tube 4 reveals the presence of an apicoplast in the organism Microscopic analysis of the contents in tube 5 reveals the presence of one large macronucleus and several small micronuclei in each organism Match the description with the correct protistarrow_forwardWhich group of organisms do not have microtubules inside their cells?
