9. KINGDOM : MONERA
•THEY ARE UNICELLULAR AND PROKARAYOTES.
• BODY ORGANISATION IS ON CLLULAR LEVEL.
MODE OF NUTRITION - Heterotroph .Well defined
nuclear membrane is absent.
Example : Bacteria , Blue – Green algae
,Cynobacteria.

18. KINGDOM PHANEROGAMAE
This division is made up of plants that bear flowers
and seeds and make up the majority of the larger
plants. The body is differentiated into true stem, leaves
and roots. Propagation of the plant takes place with the
help of seeds. Seeds are formed as a result of sexual
reproduction. The male and female gametes (sex cells)
fuse together inside the ovary (female part of the
flower) and develop into the seed. In some plants seed
is not produced inside an ovary. Phanerogamae is
made into two further divisions.
Gymnosperms (naked seeded plants)
Angiosperms (Seed borne within a fruit)

19. GYMNOSPERM
• Naked seed is the most characteristics features of
gymnosperm means seed coat are absent from the side
• Root , stem , leaves are well developed.
• Vascular bundle is well developed.
• Fruit , Flower and Seed formation takes place.
• Male and female plant are seperated and they are
unisexual
• Wood formation takes place.
EXAMPLAE- pinus , cycas

20. ANGIOSPErm
• It is the most advanced plant in the kingdom.
• All the characters are well developed in angiosperm
that is root stem and leaves are well developed.
•Vascular bundle is well developed .
• Seed coat was around the seed.
• It is divided into two types-
1. Monocotyledons (One seed leaf)
Example: Rice, Wheat
2. Dicotyledons (two seed leaves)
Example: Beans, Mango

21. MONOCOTYLEDON
The plant in which the seed can not be divided into
two equal half called monocotyledon.
Single cotyledon is called monocotyledon.
EXAMPLE – wheat , rice , maize , barley .
Paphiopedilum
dicotyledon
The seed which can be divided into two equal half is
called dicotyledon.

5. CLASS - MAMMALIA

25. INVERTIBARTES
These are those animals which are lack of vertibrate column
(backbone) called in vertibrates.
Invertebrates are animal species that do not develop a
vertebral column. This in effect includes all animals apart
from the subphylum Vertebrata. Familiar examples of
invertebrates include insects, worms, clams, crabs, octopus, sn
ails, and starfish. Taxonomically speaking "invertebrate" is no
more than a term of convenience. The vast majority of animal
species are invertebrates, since only about 3% of
animal species include a vertebral column in their anatomy. In
other words all animals except those in
the chordate subphylum Vertebrata
(fish, amphibians, reptiles, birds, and mammals) are regarded
as invertebrates.

26. general points
• Symmetry.

divided into two equal halves those animals are
called asymmetrical.

Euglena , Paramecium .

27. 2. Bilateral symmetrical - The animal which can be
divided into two equal halves they are called bilateral
symmetrical .

divided into equal parts when cute to any radii are
called radial symmetry .
