What is a
 Flower?
Reproductive structure
 of angiosperms
Consists of petals, sepals, 
stamens, and pistils
Produces seeds via pollination 
and fertilization
Parts of 
a Flower
Calyx: Outermost whorl, 
made of sepals
Corolla: Second whorl, 
made of petals
Stamen: Male part, includes 
?lament and anther
Carpel: Female part, includes 
style, stigma, ovary, and ovules
Pre-fertilisation: 
Structures and Events
Androecium: 
Male reproductive part, produces pollen
Gynoecium: 
emale reproductive organ, produces ovules
Pollination
Transfer of pollen from anther to stigma
Types: Self-Pollination and Cross-Pollination
Agents: Abiotic (wind, water) and Biotic (insects, birds)
Fertilization
Pollen reaches ovary, fertilizes ovule
Double fertilisation: One gamete forms zygote, other 
forms endosperm
Post Fertilisation: 
Structure and Events
Endosperm development
 precedes embryo
Ovule matures into seed, 
ovary into fruit
Seed and Fruit 
Development
Seed: Final product of 
sexual reproduction
Fruit: Developed from ovary,
 assists in seed dispersal
Apomixis and 
Polyembryony
Apomixis: Asexual reproduction,
 seeds without fertilization
Polyembryony: More than
 one embryo in a seed
