Our first topic we have been looking in Science has been the life cycle of plants.
We spent last term looking at each stage of the cycle.
Stage 1 – Germination
This is where the seed begins to grow. Seeds are dormant which means they are asleep. When they are given water and sunlight they begin to germinate. The first sprout is called the plumule and the first root is called the radicle.
Check out some of our drawings of seeds below…
Stage 2 – Growth
This is where the seed grows into a mature plant. Depending on the plant and the conditions it is in, determines the speed of which the seed grows into a plant.
Stage 3 – Pollination
This is where the bees play an important role in collecting pollen from the male part of the flower called the stamen. The bee carries the pollen to the next flower. From there the pollen falls onto the stigma (female flower part) and makes its way down the tube until it reaches the ovaries which are then fertilised. Check out some of our diagrams that show these steps in more detail.
Stage 4 – Fruit
Once the flower is fertilised a fruit begins to grow.
We had the chance to look at different fruits so we could see what they look like inside and the role they play in the life cycle of a plant.
Stage 5 – Seeds are dispersed
Seeds are dispersed be many different ways, either by wind, rain, animals, or even humans. Once this happens in the right conditions, the seed should begin to grow starting the cycle all over again.
Check out the video below that we have watched that shows each stage of the cycle. Our final assignment was creating a poster with the plant life cycle using all the information we have learnt over the last term.
