2. Characteristics of the Plant Kingdom 1.Plants can make their own food; they are autotrophs you know! 2. Plants have many cells with walls; we call them multicellular. 3. Plants are green… Why, you ask? Of what, you ask? Well, animals of course! You see… plants can’t move… or can they? Some say its because they have chlorophyll, others say its envy...

4. UNIT 8 Focus Topics: The Plant Kingdom  Parts of a plant – basic structures  Roots and Stems  Leaf structure & function  Leaf Types.

5. Section 8-1: Structure of Seed Plants I.The Basic Structure: A. Seed plants are:__________________ _______________________________ B. Tissue that forms a system of tiny tubes that transport water, food, and other materials is called __________ _____________. vascular (have veins) plants that produce seeds. vascular tissue

6. Section 8-1: Structure of Seed Plants C. There are two types of tissue, they are: 1) Xylem:____________________________ __________________________________ 2) Phloem:___________________________ __________________________________ 3) The main difference between xylem and phloem is that: _____________________ _________________________________ Carries water from the roots upward only in the stem. Moves food up from roots & down from leaves using the stem. where phloem can move material both ways. xylem moves material upward only,

7. Section 8-1: Structure of Seed Plants D. There are THREE major parts to the seed plant: 1) leaves:_________________________ ______________________________ 2) stems:_________________________ _______________________________ 3) roots:_________________________ ______________________________ Collect & change sunlight into food using photosynthesis. Made of xylem & phloem which transport food and water. Absorb food & nutrients and help anchor the plant in place.

8. Section 8-1: Structure of Seed Plants E. Label the three major parts to the plant: Leaf Root 1. 2. 3. Stem

9. 1. 2. 3. 5. 6. 4. flower seeds leaf fruit stem roots The Basic Plant Structure

10. Section 8-2: Structure of Seed Plants A. The function of a root is to: ____________ _____________________________________ B.There are two basic plans that can be followed for a root system: 1) Fibrous root:_______________________ __________________________________ 2) Tap root:__________________________ __________________________________ Anchor the plant and absorb water, minerals, & soil nutrients. Can also store food. Has several main roots that branch off into the soil. Has one main root with many small hair-like roots on it.

11. Section 8-2: Structure of Seed Plants C. Label the Xylem and Phloem on the diagram below: Phloem Xylem

12. Section 8-2: Structure of Seed Plants A. The function of the stem is to: _________ ____________________________________ B. The size of stems vary greatly in size. 1) A Tree Trunk is a large _____________ 2) The _____ and ________ are stems. C. There are two types of stems: 1) Herbaceous, which are: ____________ ________________________________ II. Stems: Provide transport for food and water. stem trunk branches Stems that are green and soft. 2) Woody, which are: __________________ _________________________________ Stems of wood that are hard and stiff.

13. Section 8-2: Structure of Seed Plants Trees can show their age if you look at a log or tree cutting. Trees have what are called _______ ______, which grow layer by layer each year. Count the number of rings below, and determine the tree’s age. Age of tree: ____ years old. 7 annual rings

14. Reviewing this Section: $ Why do you suppose there is a difference between xylem and phloem? $ What is the importance of a root to a plant and to you? $ What does herbaceous and woody mean? $ Explain the difference between heartwood and sapwood.
