BULAKLAK Flashcards
These are the group of leaves modified or adapted for reproduction in the angiosperms
FLOWER
Floral morphology
SEPALS, PETALS, STAMENS, PISTIL, RECEPTACLE
- It enclose the outer flower parts in the bud, outermost whorl of the flower
- Generally green in color
SEPALS
All the sepals taken collectively constitute the _______
CALYX
Types of sepals
- POLYSEPALOUS (all sepals are free from each other) (e.g. mustard, radish)
- GAMOSEPALOUS (sepals are fused with each other) (e.g. cotton, datura, brinjal)
Duration of sepals
- CADUCOUS (sepals, fall just at the time of opening of flower bud) (e.g. poppy)
- DECIDOUS (sepals fall after pollination) (e.g. mustard)
- PERSISTENT (if sepals do not fall and remain attached to the fruit) (e.g. tomato, capsicum, brinjal, cotton)
Usually the conspicuous, colored,
attractive part of a flower
PETALS
When petals are taken together, it constitute the ______
COROLLA
Types of petals
SYMMETRICAL, ASYMMETRICAL, POLYPETALOUS, GAMOPETALOUS
It is the male part of the flower lying inner to the corolla
STAMENS
Anther, filament, and connective is called ______
ANDROECIUM
It is the female part of the flower which comprises the central whorl or modified floral leaves
PISTIL
Pistil is collectively called the ______
GYNOECIUM
Pistil is consist of
- OVARY (enlarged basal part)
- STYLE (connects the ovary to the stigma)
- STIGMA (usually at the tip of the style and is receptive surface for pollen grains)
