1. A cross-section of a plant leaf. Notice the cuticle on the outermost layer (dermal tissue), the Phloem and Xylem (Vascular tissue), and the stomata on the underside of the leaf (dermal tissue).

3. Stomata – electron micrograph of the stomata. Stomata are made up of 2 guard cells that rely on turgor pressure in the cell to open or close. In both of these pictures, there is excess water and therefore the cells will expand and open the hole, allowing water to leave the plant.

4. Xylem Phloem

5. Lateral meristem tissue makes the plant grow in diameter. This is important because it allows the plant to support its height. This is why trees can grow to be so tall!! Also, these rings tell a lot about the health of the tree and how old it is!

6. MonocotDicot Seed Monoocots have 1 seed leaf and dicots have 2! These seed leaves are called cotyledons Flowers Monocots have 3 petals or multiples of 3 and dicots have 4-5 or multiples Leaves Monocots have parallel veins and dicots have a network of veins Pollen Monocots have 1 furrow and dicots have 3 Stems Monocots have interdispersed vascular bundles and dicots have a ring of vascular bundles

7. In Dicot stems, vascular systems have a ring-like arrangement In most monocot stems, vascular systems are scattered throughout
