Ch.2.less.2.how do plants grow, develop and reproduce

  1. 1. CHAPTER 2: LESSON 2: HOW DO PLANTS GROW, DEVELOP AND REPRODUCE?
  2. 2. Parts of the plant Flower Stem Leaves Roots
  3. 3. Needs of plants Water Sunlight Nutrients Carbon dioxide
  4. 4. Functions of Parts of the plant The flower forms seeds and fruits. (production of new plants) The stem takes water and nutrients from the roots. The Leaf takes water and nutrients (from stem) and sunlight and carbon dioxide (from the air) to make the plants food. 1) Anchors the plant in the soil. 2)The roots takes water and nutrients from the soil.
  5. 5. PARTS OF A FLOWER
  6. 6. Stame n Stigm a Style Anthe r Filame nt Pistil Ovary Petal Ovule Sepal Receptac le Egg
  7. 7. Sepal Protects the bud.
  8. 8. Stigma Stame n The male part of the flower. (The anther produces pollen) Anthe r Filame nt (Sticky surface to catch the pollen) Style (Tube) Ovary Pistil (The female part of the flower) (Tube) Petal Brightly coloured to attract insects.
  9. 9. Pollinatio n (The transfer of pollen from stamen to pistil)
  10. 10. Ways of Pollination By insects or birds By wind
  11. 11. Pollination by insects or birds Nectar (sweet liquid), colourful petals and scent attract the insect and birds Pollen sticks to their body. When pollinator goes to another flower the pollen sticks to the pistil.
  12. 12. Types of Pollination Self pollination Cross pollination The male pollinates the female of the same flower. The male pollinates the female of another flower.
  13. 13. What happens after Pollination? A pollen tube grows from the pollen to the egg. The pollen enters the egg (FERTILISATION)
  14. 14. What happens after fertilisation? A pollen tube grows from the pollen to the egg. The pollen enters the egg (FERTILISATION)
  15. 15. Structure of seed Protects the seed Stores food for embryo. Baby plant
