Flowers have reproductive organs called pistils and stamens. Pistils are the female organs and stamens are the male organs. Flowers can be classified based on their parts, symmetry, sex, composition, and inflorescence. Pollination is the transfer of pollen from the anthers to the stigma and can be cross-pollination between plants or self-pollination within a plant. Common agents of pollination include wind, water, insects, mammals, and birds.

5. REPRODUCTIVE ORGANS
 PISTIL – female reproductive organ of
the flower which includes the:
 Stigma
 Style
 Ovary
 STAMEN – male reproductive organ
 Anther
 Filament

6. CLASSIFICATION OF FLOWERS
Accdg. to PARTS:
 COMPLETE FLOWER
A flower having all four floral parts:
sepals, petals, stamens, and carpels.
 INCOMPLETE FLOWER
A flower lacking either sepals, petals, stamens, or
pistils

7. CLASSIFICATION OF FLOWERS
Accdg. to SYMMETRY:
 REGULAR FLOWER – a radially symmetric
flower.
Examples:
WATER LILY DAISY

8. CLASSIFICATION OF FLOWERS
 IRREGULAR FLOWER – a flower in
which one or more members of a whorl
differ in form from other members
 Example: Pea flower

9. CLASSIFICATION OF FLOWERS
Accdg. to SEXES:
 PERFECT – flower showing both carpels
and stamens
 IMPERFECT – flower with only one
reproductive organ, either female or male

10. CLASSIFICATION OF FLOWERS
Accdg. to COMPOSITION:
 SIMPLE – a flower head made up of few flowers
 Example: Gumamela
 COMPOUND - a flower head made up of many
small flowers appearing as a single bloom.
 Example: marigold

11. INFLORESCENCES
 It is the mode of development and
arrangement of flowers on an axis.

12. TYPES OF INFLORESCENCE

13. EXAMPLES
UNIPAROUS UMBEL
RACEME CYME

14. EXAMPLES
CAPITULUM SPIKE
BIPAROUS CYME

15. EXAMPLES
CORYMB
SPADIX

16. POLLINATION
 The transfer of pollen from the anthers
of a flower to the stigma of the same
flower or of another flower.

17. TYPES OF POLLINATION
 Cross-pollination - occurs when pollen is
delivered to a flower from a different plant
 Self-pollination - occurs when pollen
from one flower pollinates the same flower
or other flowers of the same individual

18. AGENTS OF POLLINATION
 Wind
 Water
 Insects
 Mammals
 Birds
