1. Plant Structure and Function

2. Plant Cells Cell TypeExampleFunctions Parenchyma Storage Photosynthesis Gas Exchange Protection Tissue Repair and Replacement Collenchyma Support for surrounding tissues Provides flexibility for plant Tissue repair and replacement Sclerenchyma Support Transport of materials

3. Plant Tissue Meristematic Tissue – Involved in growth Dermal Tissue – Outer layer of plant, also secretes the fatty cuticle Vascular Tissue – Xylem: Carries water and minerals from the root of the plant to the leaves. - Phloem: Carries food to all parts of the plant Ground Tissue -Involved in photosynthesis, storage & support -Makes up most of the plant

4. Roots Usually the first structure to grow out of the seed when it sprouts Mainly take in water and dissolved minerals Anchor the plant Grow as deeps as 50 m and wide as 15m

5. Root Systems & Adaptations TypeTaproot SystemFibrous Root System Modified Root Example Function Anchors plant Food and water storage Anchors plant Rapid water storage Water storage

6. Stems o Main function is to support the plant’s leaves and reproductive structures o Can also transport water and dissolved minerals o Stems come in many different forms Soft & flexible (annuals) Rigid & fibrous (palm) Sturdy & woody (trees) Covered in bark

7. Leaves Main function is photosynthesis Petiole attaches stem’s vascular system to leaf’s vascular system Palisade Mesophyll is where photosynthesis happens Spongy Mesophyll is where gas exchange occurs

8. Characteristics of Leaves Leaf TypeLeaf VenationLeaf Arrangement

9. Flowers

10. Flower Organs  Sepals: Protect the flower bud  Petals: Usually colorful structures that can both attract pollinators and provide them with a landing platform  Stamens: male reproductive organs  Pistil (carpel): female reproductive organs
