ACTIVITY 8 Flashcards
FLOWERS are the ____ unit of _____ (what division)
- reproductive
- angiosperms
sterile part of the flower?
perianth
combined part of a flower containing the CALYX and COROLLA
perianth
2 functions of flowers
- attract pollinators
- produce fruit and seed
2 main reproductive processes that occur in flowers?
- meiosis
- fertilization
FLOWER - 4 whorls
- calyx
- corolla
- androecium
anthers
filaments - gynoecium
stigma
style
ovary
TEPALS
sepaloids tepals
tepaloid sepals
petals and sepals mix
- tepals like sepals
- sepals like petals
how many petals and sepals on monocot
how many flowers on dicot
MONOCOT: 3 petals, 3 sepals
DICOT: 5 petals
COMPLETE VS INCOMPLETE
complete - 4 whorls
incomplete - lacks 4 whorls
PERFECT VS IMPERFECT FLOWERS
IMPERFECT CAN BE… (2)
perfect: bisexual
imperfect: staminate or pistillate
DIOECIOUS vs MONOECIOUS
DIO: male or female are in separate plants
MONO: both male and female in a plant
*ang perfect at imperfect ay within a flower, ito ay within a plant
actinomorphic VS zygomorphic
actino: radial symmetry in petals
zygo: bilateral symmetry in petals
FLOWER FUSION
- Free structure
- Connation
3, Adnation
- no fusion
- fusion between similar organs in same whorls
- fusion between dissimilar organs in different whorls
MONOCARPUS vs APOCARPUS VS SYNCARPUS
M: 1 carpel, 1 pistil
A: unfused carpels (3 carpel, 3 pistil)
S: fused carpels (3 carpel, 1 pistil)
filaments of gumamela
monoadelphous
polypetalous vs gamopetalous
poly: free petals
gamo: fused petals
ray florets vs disk florets
ray florets - attract pollinators
disk florets - real flowers
solitary vs inflorescence
s: flowers are not clustered
i: flowers are clustered
stalk of a solitary flower
peduncle
stalk of each floret in inflorescence
what do u call those w/o this
pedicle
sessile
another part found in flower
receptacle
TEPALS are usually seen in (dicot or monocot?) + example
monocot - lillies
pistil vs carpel vs gynoecium
Gynoecium = all carpels in a flower.
Carpel = individual reproductive unit.
Pistil = can be a single carpel or a group of fused carpels.
epipetalous vs epiphyllous vs gynandrous
Epipetalous – Stamens are attached to the petals.
Epiphyllous – Stamens are attached to tepals.
Gynandrous – Stamens are fused with the gynoecium (female reproductive part).
