Make a Flower LabASIM Biology
Biology COS Objective 10
IntroductionIn this lab, we will be studying angiosperms. Angiosperms are vascular plants (have water and nutrient conducting structures) that produce flowers, which contain the plant’s reproductive organs.
Within the flower, seeds will be produced.In angiosperms, seeds are enclosed in a structure called the ovary, which will mature into a fruit.
There are four major floral parts:
a corolla -the collective name for the petals, which are above the sepals and are usually brightly colored and sometimes scented to attract pollinators
a calyx -collective name for the sepals, which are the leaf-like structures at the flowers base to protect the developing bud
stamen(s) - the male portion of a flower
pistil(s) - the female portion of a flower

For the next few slides, view the pictures and decide if
the flower shown is a monocot or a dicot!
