Zorluk: OrtaHigher Invertebrates: Annelida, Mollusca, Arthropoda, and Echinodermata

Match each phylum of higher invertebrates on the left with its characteristic anatomical or diagnostic feature on the right.

  • AnnelidaMetanephridia opening into the coelomic cavity for waste excretion
  • MolluscaChitinous rasping radula used for feeding
  • ArthropodaMalpighian tubules suspended in hemolymph for excretion
  • EchinodermataHydraulic tube feet driven by a water vascular system

Cevap

Annelida matches metanephridia; Mollusca matches radula; Arthropoda matches Malpighian tubules; Echinodermata matches tube feet driven by a water vascular system.
Each phylum is accurately paired with its definitive anatomical feature: Annelida with metanephridia, Mollusca with the rasping radula, Arthropoda with Malpighian tubules, and Echinodermata with tube feet of the water vascular system.

Adım Adım Çözüm

1
Identify the diagnostic excretory and anatomical structures for Annelida and Mollusca.
Annelids feature metanephridia filtering coelomic fluid, whereas molluscs characteristically possess a specialized rasping radula for feeding.
Metanephridia and radulae serve as key evolutionary diagnostic structures for annelids and molluscs, respectively.
2
Identify the primary excretory organs for Arthropoda and the locomotory system for Echinodermata.
Arthropods use Malpighian tubules attached to the gut, while echinoderms uniquely utilize a hydraulic water vascular system operating tube feet.
These organ systems reflect major adaptations distinguishing arthropods and echinoderms from other invertebrate lineages.
