Living Sunlight - The World of Flowers

Dear Wikiwatchers

Come and join in our musical flower dissection under the cherry tree, with Brooke, Shelby, Courtney and Nicole.

Watch the sequins sparkle in the sun as you dance to Tchaikovsky's Waltz of the Flowers...

When does it happen? Listen for the music at lunchtimes, when the sun is shining...

It's Daffodil Time!

daffodils-small-yellow-1.jpg

Daffadowndilly

She wore her yellow sunbonnet,

She wore her greenest gown;

She turned to the south wind

And curtsied up and down.

She turned to the sunlight

And shook her yellow head,

And whispered to her neighbour

"Winter is dead".

- A.A. Milne

Wikiwatchers, did you know...?

The word daffodil comes from a very old English word

affodell which means early-comer. It is one of the first flowers

to open in spring.

400 years ago affodell turned into daffadowndilly and daffodil.


'She turned to the south wind and curtsied up and down.'

A Daffodil Wind Vane!

Can you see how the daffodil turns away from the (purple) wind?

That's because of the shape of its stem! Most flowers have round stems.

If you cut across a daffodil stem it is shaped like a lemon.

When the wind blows against the stem, its shape twists the flower

away from the wind and stops the stem breaking. It takes a very

strong wind to blow over a daffodil!

Here's the daffodil's cut-across stem under the microscope...

Dissect a Daffodil... it's very interesting!

Parts of a Flower

Cut across the stem to see its lemon shape.

It's very sticky! Can you see some tiny tubes?

These move water and minerals up the stem from the

roots.

There are 6 petals - 3 inside ones and 3 outside ones.

The petals all join together at the bottom of the cup.

The cup is called the corona.

P1240981-2.JPG

The brown spathe protects the bud. Can you see

its stripes? It splits open along the stripes when

the bud opens.

P1240986-2.JPG

Cut or tear off each petal. There should be 6 - 3

inside petals. and 3 outside petals.

Lay out the spathe and the petals. The outside petals

are on the top row, the inside petals are on the bottom.

Slice down the cup with the scissors and cut the

cup away. Take care! Your don't want to cut the

stamens.

P1240990-2.JPG

There are 6 stamens. Pull them off gently...

The stamens are the male part of the flower.

A stamen has a long stalk with a pollen sac at the end.

The pollen sac is called an anther.

P1240993-2.JPG

Now you are left with the long pistil and the green,

round ovary. The pistil is a hollow tube.

Feel the stigma - it's very sticky. Can you see

some pollen grains stuck to it?

The pistil, stigma and ovary are the female parts of

the flower.

P1240997-2.JPG

Carefully cut the ovary in half - can you see the 'eggs'?

Pollen travels down the hollow pistil, joins with the 'eggs'

which become seeds.

A pretty clever design don't you think?
