Earthworm is one of the most common annelids that we come across. It is a deposit feeder and shows extracellular digestive system consisting of a digestive tract along with the digestive organs. The digestive tract is a specialized tube in which the digestive contents move in one direction from the mouth to the anus. The esophagus, crop, gizzard, and intestine are the common digestive organs found in Annelids, such as the earthworm, insects, such as grasshopper, and birds, such as pigeon (refer Figure 47.4 (A), (B), and (C)).

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

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. Explain which domain, kingdom and phylum you believe this plant should be classified…
