Plant Independent Study: Dissection of a Flower
1. a) Define Monocotyledon and Dicotyledon
A monocotyledon is a class of angiosperms that has one cotyledon within the seed. It has a one seed leaf.
A dicotyledon is a class of angiosperms that has two cotyledons within the seed. It has two seed leaves.
b) Give two examples of each.
Monocots - 1. lilies 2. grasses
Dicots - 1. daisies 2. deciduous trees
2. Describe at least 4 differences between monocotyledon and dicotyledon plants.

Seed leaves, Veins in leaves, Vascular Bundles in stems, Flower parts

-Zygote develops into an embryo.
-Special tissue is produces from the sperm nucleus and the polar nuclei (endosperm), this tissue provides nutrients for the embryo.
-While seed develops in pistil, tissue in pistil wall swell and change to form fruit.
-Fruit is the mature pistil with other floral parts. The Fruit wall can be hard, tough, and opens by itself to release seeds or it can be soft so that an animal can open it to release a seed.
