disadvantages of each method.
2. Name the parts of a flower; explain their function and how wind / insect pollinated flowers
differ.

a) Plants can reproduce __________________ where there is a meeting of male and female
_____________ and _____________ . Plants can also reproduce ______________ where a piece
of stem, root etc. can be broken off from the parent and _________________ again. Pollination
is where ___________________ from the male _______________ finds its way to the female

ovary. Plants and animals have _____________________ cycles.
b) Draw the parts of the pistil and show on your drawing how fertilisation takes place.

Pollination types
Read this information about pollination, and use it to answer
the questions below.
If you want to send a letter you would probably buy a stamp and post it. If you were on a desert
island, you might push it into a bottle and throw it into the sea. If that letter was important,
though, you would be wise to put hundreds of copies into bottles and throw them all into the sea –
because the chances of one bottle drifting to the correct destination are very small.
The problem of pollination is also one of delivery to the correct destination. Wind-pollinated
flowers use currents of air to carry hundreds of tiny, light pollen grains in all directions, in the
hope that a few grains will reach the large, feathery stigma of the correct plant.
Animal-pollinated flowers make a payment – in the form of nectar or the pollen itself – to
encourage animals to deliver the pollen to the correct plant. To make sure the animal postie gets
the address right, these flowers advertise their presence with perfumes and bright colours.
Because the pollen is highly likely to reach the right place, there is no need for the great volumes
of pollen that wind-pollinated flowers produce.
Write these characteristics of flowers under the headings below.
colourful flowers
small, light pollen
feathery stigma
dull colours
distinctive scent
large amounts of pollen
heavy, sticky pollen
contains nectar

Plants use different methods to disperse their seeds. Study the drawings of fruit and seeds below, and
decide which method they are best suited to. Methods are: wind, water, hooks, popping, eaten by
animals. (There are two plants for each method.)
