2. Lateral meristem : located at branches to increase plant girth. It is responsible for secondary growth. Angiosperm Body Plan View the representative plants on display in the lab. Notice that the plants have aboveground and belowground portions. The shoot system is aboveground. What components of the plan comprise the shoot system? The root system is belowground. State two functions of plant roots. Angiosperms are divided into two different groups, monocots and eudicots. These groups differ based on tissue organization in the seed, root, stem, leaf and flowers. For example, monocots have leaf veins that form a parallel patter and flower parts in multiples of threes. Eudicots have leaf veins in a net pattern and flower parts in multiples of fours or fives. Using this information, identify the live plants on display as either monocots or eudicots filling in the table below. Monocots Eudicots Stem- ring-cortex pith Root-x or start shape V.C. Leaf-Netlike Stem- Evenly distributed Root-Circular V.C. Pith Leaf- Parallel Root There are two main root arrangements. Most monocots have a fibrous root system where all of the roots are about the same size. Many eudicots have a taproot system with one very large main root and smaller roots branching off. A carrot is an example of a taproot. 2

View the monocot and eudicot roots models on display and the cross section slides of the monocot and eudicot root. Identify the following structures: Root cap Cortex Root hairs Endoder mis Zone of cell division Pith Zone of elongation Pericycle Zone of maturation Epidermi s Xylem Phloem Use the space on the next page to draw and label the cross section of the monocot and eudicot root slides. 3

Why is the root cap necessary? It protects the roots as it lengthens How does the arrangement of xylem and phloem differ in the monocot verses the eudicot root?
