Reproduction In Flowering Plants Flashcards
(21 cards)
What is pollination?
The act of transferring pollen from anther to stigma.
What is fertilization?
Fertilization is the process in which a pollen grain fuses with the egg of an ovule.
Which parts of the flower are in the carpel ( female part of a flower )?
Stigma, style, ovary
Which parts of the flower are in the stamen ( male part of a flower )?
Anther and filament
They have large brightly coloured petals
Insect pollinated flowers
They have large brightly coloured petals
Insect pollinated flowers
These flowers have small, smooth, and light pollen grains
Wind pollinated
What is a stigma for?
A sticky surface that receives pollen
What is the style used for?
Links the stigma to the ovary
What is the ovary for?
contains ovule, which develop into seeds when fertilized
What is the anther used for?
Produces pollen
What is the filament used for?
It holds the anther
What is the sepal used for?
Protects the bud, it forms a ring called calyx
What are the petals used for?
Attract insects, it forms a ring called corolla
What do pollen grains contain?
The male gamete
What does the ovule contain?
The female gamete
What are the two kinds of pollination?
Self pollination and cross pollination
What are the two types of pollination?
Wind and insect polliantion
What is self pollination?
Transfer of pollen from anther to the stigma of the same flower or of different flower on the same plant
What is the advantage of cross-pollination over self-pollination?
Cross pollination ensures the exchange of genetic materials from different plants and results in greater variation
What is the advantage of self-pollination over cross-pollination?
If there are no pollinating insects and If plants of the same species are growing in isolation.
