  1. Natural Sciences and TechnologyGrade 5 Term 1: Life and Living Life Cycles (PPT 1)

  2. Topic 5 Life Cycles Growth and development Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  3. What is a life cycle? This is the process that an animal or plant moves through from the moment that it is created until the time that it dies. Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  4. There are many different types of animals and plants on our planet. • They have different life cycles – think about how the life of a frog or chicken starts and how a cat’s life begins? Different ways of growing Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  5. The flowers produce pollenandunfertilized seeds (these can't yet grow new plants). Insects, birds or other animals carry the pollen from one flower to the next - this is called pollination. Thepollen fertilizes the ovules in the flower. The fertilized ovules now develop into seeds. With fruit plants the seed first grows into a fruit. The seeds are then dispersed and start to grow in a new place. Plant life cycle Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  6. Plant life cycle Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  7. Fruit and flowering plants Flowers and fruit plants have slightly different life cycles. Both involve flowers,but with a fruit the flower dies and as the seed grows into the fruit – so fruit trees have extra bits to their cycle. Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  8. Flower life cycle Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  9. Life cycle of tomato plant Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  10. Important words in the Plant Life Cycle Germination With water, light and the right temperature the plant sprouts roots and a stem and grows. Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  11. Important words in the Plant Life Cycle Growth The plants stem and leaves grow upwards towards the sunlight The leaves unfold and the roots grow down into the ground. Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  12. Pollination Insects attracted to the plant transport the pollen to other plants Sometimes birds transport the pollen or animals. Important words in the Plant Life Cycle Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  13. Fertilisation This is when the pollen and the ovule join together in the inside of a flower to make a seed and create life. Important words in the Plant Life Cycle Gr 5 Natural Sciences and Technology – Term 1, Topic 5

  14. Seed Dispersal This is when seeds are spread by birds or other animals and the plant cycle starts all over again. Important words in the Plant Life Cycle Gr 5 Natural Sciences and Technology – Term 1, Topic 5
