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

Today, we will learn… • How to identify 5 plant parts: • roots, leaves, stem, fruit, flower • The function of each plant part
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
Illustrate! Fibrous Root System Taproot System
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
Consider… Why may the root hairs, root cap, and meristem be located the way they are on the root?
LEAVES • food manufacturing factory of the plant • performs PHOTOSYNTHESIS • contains the green pigment CHLOROPHYLL • makes photosynthesis possible
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.
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
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
LEAF TYPES • simple leaves • compound leaves • needle leaves
Predict:Which leaf type is which? Simple Leaves Compound Leaves Needle Leaves
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!
STEMS • Made up of nodes and internodes • Central support structure of the plant
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)
FLOWER • Contains four main parts • SEPALS • PETALS • STAMENS • PISTILS
