animal kingdom Flashcards
.1. In which phylum do the adults exhibit radial symmetry and larva exhibit bilateral symmetry?
Echinodermata
How are pneumatic bones and air sacs important in aves?
Pneumatic bones are hollow filled with air which helps them in flying. Air sacs are the air reservoirs. They also regulate body temperature and act as cooling devices
Amphibia Air Bladder
Mammals Cartilaginous Notochord
Chondrichthyes Mammary Glands
Osteichthyes Pneumatic bones
Cyclostomata Dual Habitat
Aves Sucking and circular mouth without jaws
Amphibia- Dual Habitat
Mammals- Mammary Glands Chondrichthyes- Cartilaginous notochord Osteichthyes- Air bladder
Cyclostomata- Sucking and circular mouth without jaws
Aves- Pneumatic bones
what are diploblastic animals
Diploblastic animals are those in which cells are arranged in two embryonic layers, internal endoderm, external ectoderm. For eg., coelenterates.
what are triploblastic animals
triploblastic animals are those that have a mesoderm along with the ectoderm and endoderm. For eg., chordates
Provide a technical term for the following:
1-Blood filled cavity in arthropods
2 A stinging organ of jellyfish
3 Free-floating form of Cnidaria
4 Lateral appendages in aquatic annelids
1 Haemocoel
2 Nematocytes
3 Medusa
4 Parapodia
Give an example of:
An oviparous mammal
Roundworm
A limbless reptile
Fish possessing poison sting
Duck-billed Platypus
Ascaris
Ichthyophis
Trygon
Mention the role of the radula in Molluscs.
The radula helps in scraping and scratching the food and creates depressions in the rocks. Molluscs use rocks as their habitat.
. What do you understand by metagenesis? Give an example.
Metagenesis is the phenomenon in which one generation of plants and animals reproduces asexually followed by sexually reproducing generation.
eg., Coelenterates.

eg., Coelenterates.
What is bioluminescence? Give an example.
The production and emission of light by a living organism is known as bioluminescence. It is widely seen in marine animals, in some fungi, and a few terrestrial invertebrates. Jellyfish and fireflies exhibit this phenomenon
How do endoparasites survive inside the body of the host?
1 Anaerobic respiration.
2 Exchange of gases through the body surface.
3 They possess an additional organ for attachment.
4 Well-developed reproductive organs.
5 A thick body covering is present.
6 They have no locomotory organs.
7 Tapeworms do not have a digestive system and absorb the digested food of the host.
Mention two similarities between Aves and Mammals.
Both Aves and Mammals are homeotherms, i.e., warm-blooded. They have a four-chambered heart
What is the function of feathers in birds?
1 The feathers help in maintaining body temperatures.
2 They provide airfoil shape for wings to help in flight.
3 They act as the secondary sex characters in both the sexes.
4 The colour and markings help in attracting mates.
Name the classes of vertebrates with two, three and four-chambered hearts.
1- Two-chambered hearts– Fish One atria and one ventricle are present. The oxygenated and deoxygenated blood mixes together.
2- Three-chambered hearts- Amphibians Two auricles and one ventricle
3- Four-chambered hearts- Mammals Two auricles and two ventricles
