Plant growth and flower Flashcards
do a worksheet on flowers name make sure you know the structure of the flower and can name them
in ur iPad
what is a stamen made of ?
- stamen is made out of anther and filament
what is the male gamete in a flower ?
The male gamete in a flower is the pollen .
what is the name of the female gamete in a flower ? and what is inside ?
The female gamete is called a pistil , it contains (Stigma , Style and ovary)
why are flowers brightly coloured ?
Flowers are brightly coloured to attract insects to help with plants to reproduce .
what is the function of the stamen ? the male gamete ? what is the male gamete made out of ?
The stamen is made out of a filament and a anther .
The function of the anther (produces pollen that contains the male gamete)
The function of the filament (holds the anther, it is also tall which makes it easier for the insects to transfer pollen )
What is the Function of the stigma ?
Stigma is a site for pollen to be deposited and produces the female gamete (ovule)
what is the function of style ?
The function of style id it connects the stigma to the ovary .
what is the function of a petal ?
It is a coloured part that attracts animals to allow pollination .
What is the function of a ovary ?
It produced eggs (ovule) the female gamete .
what is the function of the sepal
It supports and protects the flower bud .
what is pollination ?
Pollination is the transfer of pollen from anther to stigma .
what are the different type of pollination ? state the difference
- self pollination ( pollen grains from the same flower or same plant lands on the stigma )
- cross - pollination (pollen grains from a different plant lands on another plant )
different type of ways pollen gets transferred .
- wind - pollination
2. insect pollination
what does all flowers have ?
A flower has both female and male gamete .
what is fertilisation for a plant ? and what dos it form ?
Fertilisation is the fusion of male and female gamete . it forms a zygote , fertilisation is only complete when a zygote formed .
what does the zygote become ?
The zygote becomes an embryo
what does an ovule of a flower become after fertilisation ?
the ovule becomes a seed after fertilisation
where do plant get their water ?
Plants get their water through xylem cell
what does the ovary of a flower become after fertilisation ?
the ovary becomes a fruit .
what is seed dispersal ?
seed dispersal is the movement , spread or transport of seed away from the parent plant .
what are the different type of seed dispersal ?
- wind
- animals
- explosion
What completes fertilisation in flower ?
The formation of zygote
What is fertilisation of plants ?
The fusion of the female and male gamete nuclei to form a zygote
