- 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?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 ApicomplexansThe termite gut environment is lacking a fresh supply of oxygen O2. However, it is rich with food due to the presence of bacteria that contain enzymes capable of breaking down cellulose and lignin, the macromolecules that make wood. Use this information to determine which of following protista groups is more likely to be found in a termite gut. Diatoms Radiolaria Parabasilids O Rhodophyta O Foraminifera (Forams)
- 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 prot ist has been isolated and is on a microscope slide. How could you determine whether it belongs to te Apicomplexans or Excavata supergroup? Look for flagella which would indicate Excavata Look for flagella which would indicate Apicomplexans Look for spores which would indicate Excavata There is no way to distinguish based on structural characteristics.Pseudopodia are commonly found in protistans.

- If an ancestral protist was classified as an opisthokont, then what should be true of this protist? -They should also have given rise to the plants. -They should perform heterotrophy by secretion of exoenzymes. -Like diplomonads and parabasalids, they should bear multiple flagella. -They should be parasitic -They should be the common ancestor of the basidiomycetes and animals.Phylum Sarcomastigophor Labyrinthomorpha Apicomplexa Microspora Acetospora Myxozoa Ciliophora Habitat Symmetry Germ Layer Give two classes belonging in each phylum.
