- Outline
Reproduction in Flowering Plants
self - pollination
advantages
faster
more likely to occur
disadvantages
lesser genetic variation, less immune to diseases
harmful recessive alleles may be expressed in the offspring
how it is prevented
male and female parts mature at different times
cross - pollination
advantages
more genetic variation, offspring are more resistant to diseases
lower probability of harmful recessive alleles being expressed in offspring
disadvantages
dependent on external factors that are needed
less likely to occur
wind - pollinated
have a feathery stigma that can catch pollen grains floating in the air
stigma and style protruding out of the flower
pendulous
smooth, light pollen grains
to be easily carried away by the wind
Insect pollination
stigma and style do not protrude out of the flower
the stigma is swollen and sticky
rough pollen grains
to stick to the insects' hairy bodies
pollination
mature pollen grains land on a mature stigma
the pollen grain then germinates on the stigma due to the substance secreted by it
the pollen grain then produces a pollen tube
Fertilization
the pollen tube is then directed by the pollen tube nucleus to grow downwards towards the ovule
generative nucleus in the pollen tube divides into 2 by mitosis, forming the 2 male gametes
both are haploid in nature
enzymes are secreted to digest the stigma and style
the pollen tube grows downwards, towards the ovule and enters the ovule through the micropyle
The pollen tube bursts open and releases the 2 male gametes
one of them is attracted to the egg cell due to the smell produced by the synergids
fuses with the haploid egg cell 2 form diploid embryo
the other male gamete fuses with the diploid central nucleus containing the 2 polar nuclei
to form the triploid endosperm nucleus, which develops to form the endosperm in the fruit. The endosperm provides food for the fruit
Parts of a monocotyledonous flower
carpels
stigma
sticky and swollen structure that receives pollen grains during pollination
withered or modified to help in fruit dispersal after fertilization
style
a stalk that holds up the stigma
withered or modified to help in fruit dispersal after fertilization
ovary
where fertilization occurs
contains ovules that will develop into seeds after fertilization
develops into fruit after fertilization
ovary wall
protective layers around the ovary
develops into the fruit wall after fertilization
ovules
develop into seeds after fertilization
stamens
anther
contains pollen sacs which contain pollen grains
contains vascular bundle
withered or modified to help in fruit dispersal after fertilization
filament
supports the anther
positions anther in a suitable position for dispersal of pollen grains
withered or modified to help in fruit dispersal after fertilization
sepals
modified green leaves that protect the flower bud and petals
together they make up the calyx
withered or modified to help in fruit dispersal after fertilization
petals
modified leaves
together they make up the corolla
brightly coloured in insect pollinated flowers; small or absent for wind pollinated ones
withered or modified to help in fruit dispersal after fertilization
recepTacle
enlarged end of flower stalk
bears other parts of the flower
pedicel
holds the flower in proper position
