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 diesNATURAL SCIENCES GRADE 5

Different Ways of GrowingYou have already learnt that there are many different types of animals and plants on our planet

Their differences sometimes mean that they have different lifecycles think about how the life of a frog or chicken starts and how a cats life begins?NATURAL SCIENCES GRADE 5

Plant Life CycleA plant life cycle begins when a seed germinates and then grows into a seedling

NATURAL SCIENCES GRADE 5

Fruit and Flowering PlantsNATURAL SCIENCES GRADE 5

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

Plant Life CycleThe 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 pollinationThe pollen fertilizes the ovules in the flowerThe fertilized ovules now develop into seedsWith fruit plants the seed first grows into a fruitThe seeds are then dispersed and start to grow in a new placeNATURAL SCIENCES GRADE 5

Important Words in the Plant Life CycleGermination

With water, light and the right temperature the plant sprouts roots and a stem and grows

NATURAL SCIENCES GRADE 5

Important Words in the Plant Life CycleGrowth

The plants stem and leaves grow upwards towards the sunlightThe leaves unfold and the roots grow down into the ground

NATURAL SCIENCES GRADE 5

Important Words in the Plant Life CyclePollination

Insects attracted to the plant transport the pollen to other plants Sometimes birds transport the pollen or animalsNATURAL SCIENCES GRADE 5

Important Words in the Plant Life CycleFertilisation

This is when the pollen and the ovule join together in the inside of a flower to make a seed and create lifeNATURAL SCIENCES GRADE 5

Important Words in the Plant Life CycleSeed Dispersal

This is when seeds are spread by birds or other animals and the plant cycle starts all over againNATURAL SCIENCES GRADE 5
