Fruit and Flower lab

I am giving you a handout which is like a  colouring book showing the structures of flowers, leaves and fruit.  It is from the "Botany Colouring Book", a resource for university level botany courses.

Use this as a reference.


FLOWER LAB IS OUT OF 20 MARKS
Go into the school garden and find the following specimens.  Bring them back for dissection and observation under the dissecting microscope.
Draw each specimen.  2 marks
Identify the flower type and label the parts.  2 marks
Write one interesting observation you notice  1 mark

 Each drawing should be at least a half page.  You should have three specimens.  If you cannot find the flower, show me a pic from the internet that shows the same kind of flower.

Use a blank paper to draw your observations.

1.  Find a small HEAD type of flower  (simlar to a sunflower)  It ought to have a disk flower and ray flower within the head.  Observations:  Count the disc flowers in your specimen.  What is the advantage of this kind of flower?
