  1. Plant Parts and Functions

  2. Parts of The Plant • Five basic parts • Leaves • Stems • Roots • Flowers • Fruit

  3. Roots 2 Types of Root Systems • Taproot System Primary root grows down from the stem with some small secondary roots forming Examples: Carrots & Turnips

  4. Roots • Fibrous System Small lateral roots that spread out just below the soil’s surface Examples: Corn & Beans

  5. Root Functions Roots have 4 primary functions 1. Absorption of water and nutrients (performed by root hairs) 2.Transportation of water and nutrients to stem 3. Anchor plant to maintain stability 4. Store food and water

  6. Leaves Main body of leaf Attaches blade to stem

  7. Important Functions of Leaves • Photosynthesis Process that plants use to produce their food • Transpiration Loss of water and exchange of carbon dioxide

  8. Parts of the Stem • Node Areas where side branches and leaves develop from • Internode Area between nodes • Lenticles Small holes located in the stem (breathing pores)

  9. Functions of the Stem 1. Transports water and nutrients from roots to leaves 2. Supports leaves, fruits and flowers 3. Food Storage

  10. Fruit Classification Aggregate Develop from a single flower with many ovaries Examples: Strawberries & Tulips

  11. Fruit Classification Multiple Fruit develops from a group of tightly clustered flowers Examples: Pineapples & Figs

  12. Fruit Classification Simple Develop from a single ovary Examples: Cherries & Tomatoes

  13. Fruit’s Function Site of seed production

  14. Flower Parts Pistil Female part of plant • Consists of: • Stigma • Style • Ovary

  15. Flower Parts Stamen Male reproductive organ • Consists of: • Anther • Stamen

  16. Flower Parts Petals Highly colored part of the flower, may contain perfume and/or nectar glands Sepals Small green structures on the base of a flower that protect the flower bud

  17. Flower Classification Complete flower Has all four male and female parts Incompleteflower Missing one of the four male or female parts Perfect flower Has stamens and pistils Imperfect flower Lacking either stamens or pistils

  18. Flower Function Sexual Reproduction is the flowers sole function Pollination by: Wind Insects and Birds

  19. Parts of the Seed • Embryo Growing part of seed • Endosperm Tissue that provides nutrition for the developing seed • Cotyledon Food storage tissue

  20. Parts of the Seed • Seedcoat Protective outer covering of the seed • Scutellum Absorbs the endosperm
