In fertilisation in plants this is the first step..
The pollen grain grows a pollen tube
The pollen nucleus fuses with the ovum
A zygote (fertilised egg) is formed
The pollen tube enters the ovary
3
Which part of the flower becomes the fruit coat (hard or soft)
The ovule
The ovary wall
The ovum
The stigma
4
Which is NOT an adaption of the stigma in a wind pollinated flower?
Exposed (outside petals)
Sticky end
Long
Feathery structure
5
This is the best description of pollination
The wind or insects carry pollen
An animal carries pollen from one flower to another
Pollen transfer from anther to stigma (of another flower)
The transfer of pollen from stigma to anther
6
This is typical of an insect pollinated flower
Exposed Anther
Large colourful petals
Exposed Stigma
No nectar
7
What is the best description of fertilisation?
The fusion of male and female gametes

The growing of a pollen tube
8
Which is NOT an adaption to dispersal by animals
A streamlined shape
A sweet, edible fruit coat
Light with wings or feathery hairs
Hooks or spikes on the seed
9
