The four distinguishing Chordate traits. Concept introduction: Chordates belong to the Phylum Chordata. The chordates are the highly advanced phylum and includes diverse species with varying adaptations and habitats. Chordates have a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail in their life cycle.

Concept introduction: Chordates belong to the Phylum Chordata. The chordates are the highly advanced phylum and includes diverse species with varying adaptations and habitats. Chordates have a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail in their life cycle.

Expert Solution & Answer

Explanation of Solution

The Phylum: Chordate shares the following distinguishing characters from invertebrates. These characters are expressed during their embryonic development or post-embryonic development.

Notochord
The notochord derived from the mesoderm is present in the anteroposterior axis of the chordates made of a substance similar to cartilage. The notochord is found closer toward the dorsal side than the ventral side. The notochord gives rise to nucleus pulposus of the vertebrae in higher chordates.
Dorsal tubular nerve cord
Only chordates have dorsal nerve cord that is derived from the ectoderm. The nerve cord during embryonic development later gives rise to the central nervous system during development.
Pharyngeal gill slits
The invertebrate chordates are filter feeders that feed with the help of pharyngeal gill slits. The pharyngeal gill slits later developed into gills of the aquatic chordates. The higher non-aquatic vertebrates have pharyngeal gill slits during development.
Post anal tail
Tail is the extension of the body that gives balance for movement. The tail extends beyond the anus and occurs lifelong in most vertebrates. In tailless vertebrates like humans, it occurs during embryonic development.

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
