  1. For the Instructor • Upon completion, students will be able to: • Identify plant parts including, roots, leaves, stem, fruit, and flower •  Describe general function of each of the above listed plant parts • Students will understand the importance of plant part identification as a consumer and for SAE’s

  2. DiscoveringPlant Parts CLF 310: Basic Botany CLF 311: Plant Parts Christina Cefalu AgEd 410, Fall 2013

  3. Today, we will learn… • How to identify 5 plant parts: • roots, leaves, stem, fruit, flower • The function of each plant part

  4. ROOTS • Two basic types: 1 . FIBROUS root system • roots branch from the bottom of the plant • Ex. Corn, beans 2. TAPROOT root system • where a long tapering root develops • Ex. Carrot, dandelions

  5. Illustrate! Fibrous Root System Taproot System

  6. PARTS OF THE ROOT SYSTEM • Root Hairs • Absorb water, nutrients, minerals • Root Cap and Meristem • connective tissue • Involved in growth • Move moisture and nutrients to the plant

  7. Illustrate!

  8. Consider… Why may the root hairs, root cap, and meristem be located the way they are on the root?

  9. LEAVES • food manufacturing factory of the plant • performs PHOTOSYNTHESIS • contains the green pigment CHLOROPHYLL • makes photosynthesis possible

  10. Consider… The leaf captures light and turns it into energy. What functions may a plant need energy for? Give two possible functions on your handout.

  11. The Leaf is Composed of… • 1. The STOMATAS • small openings on underside of the leaf • help cool the plant through the TRANSPIRATION of water • 2. The BLADE • main body of the leaf • 3. The PETIOLE • stem which attaches the blade to the main stem

  12. The Leaf is Composed of… • 4. The MIDRIB • large central vein down the middle of the leaf •  5. The APEX • tip of the leaf •  6. The BASE • bottom of the leaf • attaches to the petiole, or if petiole is absent, directly to the stem •  7. The MARGIN • edge of the leaf

  13. LEAF TYPES • simple leaves • compound leaves • needle leaves

  14. Predict:Which leaf type is which? Simple Leaves Compound Leaves Needle Leaves

  15. LEAF FUNCTIONS • Plant food factory • captures solar energy • Solar energy is converted into chemical energy in the form of sugars and starch • Gives plant the energy it needs • Leaves are nature’s solar panels!

  16. STEMS • Made up of nodes and internodes • Central support structure of the plant

  17. FRUIT • Fruit is a ripened egg, or ovule • The ovule is fertilized by the pollen • The ovary matures into the fruit • Fruit is classified by structure and number of ovules • Simple fruits (tomatoes, cranberries) • Aggregates (blackberry)

  18. FLOWER • Contains four main parts • SEPALS • PETALS • STAMENS • PISTILS
