5 Kingdom Classification Flashcards
1
Q
Classification
A
– The organization of objects / organisms using characteristics & attributes
2
Q
Species
A
Species means an organism of a particular kind whose members can interbreed
among themselves to produce fertile young ones.
3
Q
Kingdom – Monera
A
- Single celled (unicellular)
- Microscopic
- Nucleus does not have a membrane
(Prokaryotic) - DNA is distributed in cell without
being enclosed. - Absorbs food
- EX: Blue-green algae, Bacteria
4
Q
Kingdom -Protista
A
- Unicellular; microscopic
- Nucleus is membrane-bound
(eukaryotic) - Has membrane bound cell structures
- Appendages – cilia or flagella
- Nutrition – autotrophic or
heterotrophic - Absorbs, ingests or photosynthesizes
food - EX: Amoeba, Paramoecium, Euglena.
5
Q
Kingdom – Fungi
A
- Multicellular , eukaryotic
- Made up of thread like hyphae
- Absorbs food
- Saprophytes- absorbs nutrients
from dead matter - Parasites – attack living tissues
- EX: Mushrooms, Yeast, Mildew,
Mould
6
Q
Kingdom – Plants
A
- Multicellular, Autotrophic
- Eukaryotic
- Photosynthesizes food
- Specialized cells and structures
- Rigid cell walls for support
- EX: Mosses, Flowering plants,Ferns,
Algae
7
Q
Kingdom - Animalia
A
- Multicellular, eukaryotic
- Specialized cells & structures,
including tissues, organs, organ
systems - Locomotion
- Heterotrophs
- No cell walls
- EX – Worms, Spiders, Snails,
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
