Kingdom Animalia Flashcards
(31 cards)
Kingdom Animalia nutritional mode compared to other Kingdoms
Heterotrophic, eating other organisms
Kingdom animalia cell structure compared to other kingdoms
No call walls
Kingdom animalia reproduction and development vs other kingdoms
Gametes (eggs and sperm), zygotes.
Theorized ancestor of all living animals?
A suspension feeder similar to present choanoflagellates
Types of symmetry in animals? How does symmetry relate to lifestyle?
Radial: Sessile or planktonic (floating around), able to face stuff from any direction
Bilateral: Coordinate and move, turn to face stuff.
Animals with two germ layers are…
Dipoblastic
Animals with 3 germ layers are…
Triploblastic
All bilaterally symmetrical animals are ____blastic
Triploblastic
A body cavity between the digestive track and outer body wall
Coelom
Having a pody cavity, having a psudo body cavity, having no body cavity
Coelomate, Pseudocoelomate, Acoelomate
Phylum Porifera Overview
Sponges
No true tissue
Aquatic environments
Suspension feeders
What are cnidocytes and nematocytes
Cinidocytes are special cells used for defense or prey capture
Nematocytes has a stinging thread to capture prey
Specific to Cnidarians (Medusa and polyps (jelly fish))
Phylum Platyhelminthes
Flatworms
Flattened for gas exchange
Acoelomate
Gastrovascular cavity
Heterotrophs (sometimes parasites)
Hermaphrodites (sometimes asexual)
Aquatic and damp environments
Phylum Rotifera
Rotifers
Small animals that live in aquatic and damp environments
“Alimentary canal” digestive tube with two openings (mouth and butt)
Phylum Mollusca
3 main parts: Foot, visceral mass, mantle
Radula (scraping tongue thing)
Aquatic and damp places
Hydrostatic skeleton
Often has hard shell
Many are hermaphrodites
Diversity
Phylum Cnidaria
Sessile or planktonic (still or floating)
Polyp or Medusa body types (jellies)
Gastrovascular cavity
Radial symmetry and diploblastic
Predators (tentacles to capture)
Hydrostatic skeleton
Nerve net (contractile fibers)
Phylum Annelida
Segmented worms (earth worms)
Moist places
Important decomposers
Digestive system
Closed circulatory system
Phylum Nematoda
Roundworms
Psudocelomate
Cuticle*
No circulatory system
Aquatic and moist places (and bodies, parasites)
Phylum Arthropoda
Nearly all habitats
Most successful animal phylum
Exoskeleton (Chitin)
Special organs for gas exchange
Segmented bodies
Two or more pair of jointed legs
Phylum Echinodermata
Starfish, urchins, sea cucumbers
Sessile or slow moving
Endoskeleton
Adults with Radial symmetry but bilateral as larvae
Phylum in Deuterostomia clade
Echinidermata (starfish)
Phylums in clade Lophotrochozoza
Platyhelminthes
Rotofera
Mollusca
Annelida
Phylums in Ecdysozoa
Nematoda and Arthopoda
Only Radial phylum we are learning about
Cnidaria
