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 and FRUIT LAB part 1
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.
Use a blank paper to draw your observations.
SPECIMENS: FOR EACH NUMBER BELOW, USE HALF A PAGE TO DRAW THE FOLLOWING:
1. Find a small HEAD type of flower and draw it (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?
