Concept explainers
To enlist:
The characteristics and representatives of the given animal phyla.
Introduction:
Animal phyla include a list of the major groups of animals that include invertebrates and vertebrates. Invertebrates are the animals that do not have a backbone and the vertebrates are the backbone bearing animals.

Explanation of Solution
The key characteristics and the representatives of the animal phyla are described in the following table.
Phylum |
Characteristics |
Representatives |
Sponges |
They are included in phylum porifera. It is a simple animal with no mouth, heart or muscles. It is sessile animal containing many pores and cells for filter feeding. Asymmetrical. |
Sponges and common bath sponge. |
Cnidarians |
They are aquatic animals. Coelom is absent. They contain cnidocyte cells to capture prey. Radial symmetry. |
Sea anemone, jellyfish, corals and Obelia. |
|
Included in phylum Platyhelminthes. No body cavity. Bilateral symmetry. |
Planaria and tape worms. |
Nematodes |
They have complete |
Roundworms and hookworms. |
Molluscs |
They have a soft and unsegmented body. Have mantle and the muscular foot. |
Snails, squids, octopus and mussels. |
Annelida |
They are the true segmented worms. Have closed circulatory system. |
Earthworms and leeches. |
Arthropods |
Presence of jointed legs, antennae, exoskeleton and closed circulatory system. Bilateral symmetry. |
Insects, crab and millipedes. |
Echinoderms |
They have spiny skin, water vascular system, body containing 5 equal segments and tube feet. Radial symmetry. |
Star fish and sea urchin. |
Chordates |
Presence of notochord, dorsal nerve chord, gill slits and bilateral symmetry. |
Mammals, fish, birds, reptiles and amphibians. |

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas.
