Summary Introduction
To label: The structure of Paramecium and explain to which clade, subgroup, and super-group it belongs to.
Introduction: Protists belong to domain Eukarya. They show more structural and functional variation as compare to the other eukaryotes. The classification of the protists into the phylogenetic tree clade includes the species of the plants, animals and the

Carotenoids in algae have evolved through primary and secondary endosymbiosis. provide a well-constructed phylogenetic tree to show where carotene, neoxanthin, zeaxanthin, violaxanthin, fucoxanthin, and lutein arose in the macrophytic, multicellular groups of algae. add descriptive and informative title to it
Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features.
1) Symmetry: Asymmetrical, Radial, or Bilateral
2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic)
3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate
4) Developmental mode (if Coelomate): Protostome or Dueuterostome
Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla.
* Please answer 1) and 2) only. Reposting question for other two to be answered.
Your lab group is assigned an unknown organism to identify to the level of phylum. You have it narrowed down to either Phylum Porifera or Phylum Cnidaria. Which feature would allow you to identify the phylum of your unknown creature?
a) Presence of one or more germ layers
b) Presence of a central cavity
c) Presence of flagellated cells or cells with a long tendril extension
d) Presence of one large external opening
e) Presence of epidermal covering
