  1. Parts of Plant

  2. Main Parts of Plant • Vegetative Part - Organs concerned with the growth & nutrition of the plant - Responsible for the non-reproductive activity • Root or Root System • Stem • Leaves

  3. Main Part of Plant 2. Reproductive Part - Responsible for the production of new individual plant • Flowers • Fruits • Seeds

  4. VegeTATIve part

  5. ROOTS • For anchoring the plant and absorption of water and mineral • Cylindrical in form and are usually colorless or have some color

  6. Types of Root System • Taproot • Has a primary root where the lateral root arises • Typical of the dicot

  7. Types of Root System 2. Fibrous • More or less the same size originating directly at the base of the stem • Characteristic of monocot

  8. Type of Root System 3. Adventitious - Arise from any part of the plant body

  9. Parts of the Root

  10. Stem • Ascending axis of the plant body for support and conduction

  11. Types of Stem Herbaceous Stem Woody Stem Tough and not green Considerable growth in diameter Tissue chiefly secondary Chiefly perennial Covered by corky bark Buds chiefly covered by scales • Soft and Green • Little growth in diameter • Tissue chiefly primary • Chiefly annual • Covered by an epidermis • Buds mostly naked

  12. Types of Stem Herbaceous Woody

  13. Parts of Stem

  14. LEAVES • Expanded, flat and green • For photosynthesis and transpiration

  15. Reproductive part

  16. Reproductive Part • Flowers • Modified shoot that bears the gamete for sexual reproduction 2. Fruits • Ripened ovary • Formed as a result of union of gametes 3. Seeds • Mature ovule • Consist of embryo, endosperm, cotyledon and seed coat

  17. TYPES OF FLOWERING PLANT Eudicot / Dicot Monocot Seeds have only one cotyledon Parallel vein leaf which are usually narrow Floral part is in multiple of 3 Stem do not have lenticel • Form the largest group of plants • Netted vein leaf • Flowe parts are in multiples of 4 or 5 • Seeds with 2 cotyledon • Stem is covered with bark and tiny pores called “ lenticel”
