What is a Dicot?
A dicot is a flowering plant with two embryonic seed leaves, rather than the single embryonic seed leaf associated with monocots. Embryonic seed leaves, also known as cotyledons, are an important part of plant development, and monocots and dicots develop in different ways right from the very start. You may also hear dicots referred to as magnoliopsids, referencing the class to which they belong. The term “dicot” is actually a shortening of dicotyledon, the proper term for plants in this class. Since “dicotyledon” and “monocotyledon” are a bit of a mouthful, most biologists just say “dicot” and “monocot.” Both monocots and dicots belong to the larger phylum of flowering plants, sometimes known as angiosperms, with thousands of individual species all over the world. The cotyledons aren’t the only difference between monocots and dicots. Monocots have energy reserves in their cotyledons which are used to help the plant grow and develop, a key difference in germination. The two have differe

They should also be able to label each of the diagrams that you showed above. Compare a tap root and fibrous root. How are tissues distributed in a plant root? Describe the two main functions of roots. How is osmosis involved in the absorption of water and nutrients? Why is it important that the root endodermis permit only a one-way passage of material?
