7
Q
Kingdom - Animalia
A
- Multicellular, eukaryotic
- Specialized cells & structures,
including tissues, organs, organ
systems - Locomotion

Fishes,Birds, Elephants, Humans.
8
Q
Vertebrates
A
- Have rigid backbone and
- Have a internal skeletal system for support - endoskeleton
- Ex Fish, Frog, Human
9
Q
Invertebrates
A
- No rigid backbone or skeleton
- Some have external exoskeleton for support
– EX: Insects, Spiders
10
Q
Phylum - Porifera
A
- Simplest multicellular
- Body - hollow tube
- Many Pores (Ostia) or canals all
over the body through which water
can enter which helps in capturing
food - single and large opening on the top
through which the water exit -
Osculum - eg – Sycon and Bathsponge
11
Q
Phylum - Coelenterata
A
- single cavity – coelenteron
where digestion takes place - cavity opens by mouth at one end
- tentacles present around the mouth
- aquatic by habitat
- Exoskeleton - hard - calcium
carbonate - Eg – Hydra, Jelly fish.
12
Q
Phylum – Platyhelminthes[flat worms]
A
- small, soft, flattened body
- unsegmented body
- acoelomate (no body cavity)
- parasites or free living
- sea water or fresh water
- eg – Planaria, Liverfluke,
Tapeworm
13
Q
Phylum- Annelida
A
- Segmented or ringed body
- Cylindrical body
- well-developed digestive system
- alimentary canal opens at both ends with mouth and anus.
- true body cavity
- Eg –Earthworms, Leeches , Nereis
14
Q
Phylum – Nematoda[Roundworms]
A
- long, cylindrical body
- unsegmented body
- fluid filled or false body cavity
- Alimentary canal opens at both the
end – Mouth and Anus - mostly parasitic or live free in soil
- Eg – Ascaris, Hookworm, Eelworms in
potato plants
15
Q
Economic importance of earthworm
A
- Loosens up and aerates the soil as it burrows which
helps in respiration of roots - Interchanges top soil with the lower layers
increasing the fertility - Excreta is rich in nitrogenous matter required for
plant growth - Used in vermiculture for producing high quality
manure
16
Q
Phylum - Arthropoda
A
- Jointed legged
animals - largest number of species
- exoskeleton made up of chitin
- cast off and regrowing of the
exoskeleton during growth -
Moulting - Eg – Butterflies, Honeybees,
C ockroaches etc.
17
Q
Phylum - Echinodermata
A
- Spiny –skinned
- unsegmented
- Marine animals
- Locomotion – Tube feet
- Eg – Starfish, Brittle star, Sea urchins etc.
18
Q
Phylum - Mollusca
A
- Soft
- Unsegmented body
- hard calcareous shell
- muscular foot – locomotion and as a
weapon
Eg - Slugs, Cuttlefish, Snail,
Octopus
19
Q
Phylum - Chordata
A
- Possess a notochord
- well developed vertebral column
- body is divided into – head, trunk, two pairs of appendages
- Five class
– Pisces
– Amphibia
– Reptilia
– Aves
– Mammalia
20
Q
Class – Pisces
A
- Fishes – Bony and Cartilaginous
- Habitat- Aquatic
- Body – streamlined , head, trunk and tail.
- Heart - two chambered
- Respiration - through gills
- Exoskeleton – scaly
- Body temperature - cold blooded or poikilothermic
- Locomotion – fins
- Reproduction – Oviparous - by laying eggs
21
Q
Bony fishes
A
- Skeleton – bones
- gill slits – covered - operculum
- Paired fins, mouth terminal
- Eg– Rohu,Catla
22
Q
Cartilaginous
fish-
A
- Skeleton - cartilage
- Gill slits all open
- Unpaired fins
- Mouth is ventral
- Eg – Shark
23
Q
Class -Amphibian
A
- Land and water
- Egg and larva –
– Lives in Water
– Respires through Gills - Adult
– Lives on Land
– Respires through Moist skin/ lungs - Ear drum on skin
- Five digits limbs
- 3 chambered heart
- Cold blooded
- Eg – Frog, Toads, Salamander
24
Q
Class- Reptilia
A
- Habitats -> Terrestrial [lives on land]
- Heart-> 3 chambered, ventricle is partially divided
- Body temperature -> Cold blooded
- Respires by lungs
- Exoskeleton-> Rough, horny scales on skin
- Locomotion -> Short stout limbs,
- { exception} snake is a limbless reptile
- Rep-> Oviparous, eggs have a leathery shell.
- The eardrum tympanum – lies at the bottom of a tubular depression
- Eg – Crocodiles, Lizards, Turtles & Tortoises, Snakes etc.
25
Q
Class- Aves
A
- Warm blooded (Homeothermic)
- Four chambered heart
- Respiration by lungs
- Aerial – for flight
- Forelimbs modified into wings for flying
- Feathery exoskeleton
- Reproduction by laying calcareous eggs
- Eg – peacock, crow, sparrow, ostrich, emu
26
Q
Class - Mammals
A
- Highly developed animals
- Mostly Land – habitat
- Aquatic – Whales
- Aerial – bat
- Mammary glands –production of milk – nourishment of young ones
- Directly give birth to young ones without laying eggs (vivipary) except Spiny Anteater
and Duck billed platypus. - Hair on skin
- warm blooded
- muscular diaphragm which divides body into thorax and abdomen
- lungs for respiration
- 4 chambered heart
- external ear [Pinna]
- external testes in scrotum
