Reproduction In Flowering Plants Flashcards
(19 cards)
Parts of the stamen
Anther, filament
Parts of the carpel
Stigma, style, ovary
Function of the petal
Attracts insects
Function of the nectary
Produces nectar for insects
Function of the sepal
Protects flower bud
Function of the anther
Holds pollen (make sex cells)
Function of the ovary
Where the egg is kept
Function of the style
The pollen travels down the style to the ovary
Function of the stigma
Catches pollen
Is the carpel male or female?
Female
Is the stamen male or female?
Male
Function of the filament
To support the anther
Process of making a new plant?
Pollination Fertilisation Formation (fruit + seed developement) Dispersal (dispersing fruit + seed) Germination (Pretty flowers for dis girl)
Explain Pollination
Transfer of pollen from anther to stigma
2 types of pollination?
Wind and insect
Explain Fertilisation
Pollen lands on stigma, grows down through style, the male and female sex cells (gametes) fuse into a zygote
Explain Seed formation
The zygote becomes the seed embryo, the ovary becomes the seed coat
Sometimes the ovary swells to become soft a fleshy (the fruit)
Explain Dispersal
Seed is brought away from plant by wind, water, animal, or self dispersal
Explain Germination
When seed lands in good conditions, it will develop into a plant
