Natural Sciences and Technology Grade 5 Term 1: Life and Living Life Cycles (PPT 1)
Topic 5 Life Cycles Growth and development Gr 5 Natural Sciences and Technology Term 1, Topic 5
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
Different ways of growing 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? Gr 5 Natural Sciences and Technology Term 1, Topic 5
Plant life cycle The flowers produce pollen and unfertilized 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. The pollen 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.

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
Flower life cycle Gr 5 Natural Sciences and Technology Term 1, Topic 5
Life cycle of tomato plant Gr 5 Natural Sciences and Technology Term 1, Topic 5
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
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
Important words in the Plant Life Cycle Pollination Insects attracted to the plant transport the pollen to other plants Sometimes birds transport the pollen or animals. Gr 5 Natural Sciences and Technology Term 1, Topic 5
Important words in the Plant Life Cycle Fertilisation This is when the pollen and the ovule join together in the inside of a flower to make a seed and create life. Gr 5 Natural Sciences and Technology Term 1, Topic 5
Important words in the Plant Life Cycle Seed Dispersal This is when seeds are spread by birds or other animals and the plant cycle starts all over again. Gr 5 Natural Sciences and Technology Term 1, Topic 5
