Plant Reproduction Flashcards
Sepal…
To protect the unopened flower
Style…
A tube that connects the stigma and the ovary together
Anther…
Contains pollen grains/produces male sex cells
Petals…
Brightly coloured to attract insects
Filament…
To hold up the anthers
Stamen…
The male parts of the flower: the anther and the filament
Ovary…
Produces female sex cells (contained in ovules)
Nectary…
Produces a sugary liquid called nectar to attract insects from the scent
Stigma…
The top of the female parts of the flower and collects pollen from the anthers
Carpel/pistil…
The female parts of the flower: ovary, ovule, stigma and style
What is pollination?
Pollination is when pollen grains need to be moved from the stigma from one flower to a stigma of another flower
Insect-Pollinated…
The petals and the nectar attract insects and the insects take the pollen and stick the pollen to themselves from the stigma of one flower and moves the pollen grains to the stigma of another flower for plant reproduction
Wind-Pollinated…
This is when the pollen grains from the stigma of one flower is carried by the air currents and the pollen grains move to a stigma of another flower for plant reproduction
What is fertilisation?
Fertilisation is when the nucleus of the pollen grain drops down from the pollen tube and joins the egg cell inside an ovule in the ovary to fertilise the egg cell
What are the factors of competition in dispersal?
Light. Space. Water. Minerals in the soils.
