Study Notes
- Flashcards for NEET Biology: Animal Kingdom
Symmetry and Body Cavity
- Bilaterally symmetrical and acoelomate organisms: Platyhelminthes (flatworms)
- Radially symmetrical and acoelomate organisms: Coelenterata, Ctenophora
- Bilaterally symmetrical and pseudocoelomate organisms: Aschelminthes (roundworms)
Animal Kingdom Features and Examples
- Choanocytes are present in Porifera.
- Nematocyst is present in Cnidaria.
- Polyp is present in Hydrozoa, like Hydra.
- Medusa is present in Aurelia.
- Metagenesis is present in Obelia.
- Flame cells (solenocytes) are present in Platyhelminthes and function in osmoregulation.
Excretion, Respiration and Classification
- Nephridia are for osmoregulation and excretion in Annelida.
- Malpighian tubules are present in Arthropoda.
- Haemocyanin is a copper protein present in the haemolymph for oxygen transport.
- Water vascular system is present in Echinodermata.
- Notochord in the larval tail is present in Urochordata (Ascidia, Salpa, Doliolum).
- Notochord exists throughout the life of Cephalochordata (Amphioxus or Lancelet).
- Notochord is replaced by vertebral column in adult Vertebrata.
- Jaw-less marine fishes that migrate to fresh-water for spawning are Cyclostomata (Petromyzon, Myxine).
- Torpedo are cartilaginous fish which have electric organs.
- Chondrichthyes are cartilaginous, have a ventral mouth, placoid scales, no air bladder, and gill slits without operculum.
- Osteichthyes have a bony endoskeleton, terminal mouth, cycloid/ctenoid scales, an air bladder, and gill slits with operculum.
- Porifera have a cellular level of organisation.
- Coelenterata and Ctenophora have a tissue level of organisation.
- Coelenterata and Ctenophora are diploblastic.
- Adult Echinodermata are radially symmetrical and coelomate.
- Cuttle fish is in the phylum Mollusca, genus Sepia.
- Silverfish is in the phylum Arthropoda, genus Lepisma.
