Plant Life Cycle

 

Plants are the living things, they grow and reproduce like any other living thing. They follow a cycle process of starting a new life, growing, and then coming back to the starting stage (reproducing). Plants start their life from a seed and grow-up to become a mature plant.

 

Seed

Seeds are much like babies of the plants. Seeds contain the embryo of the plants with necessary food and an outer coating for protection. The seeds are dispersed across the land by many ways (river, air, animals, and humans). When they fall on the rich soil with necessary things, they germinate and start their life.

 

Germination and Seedling

When the conditions in the soil are just right, the seed germinates. First, it breaks the outer coating and begins growing its first roots and leaves. When the first sign of life from a seed appears out of the soil, it is called seedling.

 

Growing to maturity 

The seedling continues to grow to its full maturity. The plant needs many necessary things during its growth such as water, light and nutrients. Then plants become mature, they have to get stronger roots and an increased number of branches and leaves. At this stage, they are ready to make flowers and new seeds.

 

Flowering, Pollinating and Seeding

When plants become mature, they start to make flowers and pollen. When the pollen reaches the female part (ovary) of the flower, it fertilizes the cells inside it and produces seeds.

 

Repeating the Cycle

The newly produces seeds disperse across the land and begin their new life as a plant. This cycle of the plants is started all over again and new plants are produced.

Task: Today you are going to use what you have learnt about the processes of the plant life cycle to complete a diagram. You must draw a picture, write a title and include an explanation for each stage of the cycle. You can either draw your own cycle or use the template attached below.

Extension Task: Why not grow your own bean?

1) Use a glass  or a jar of a clear plastic cup for your growing beans experiment.

2) Line it with kitchen towel paper or cotton wool buds. Then tuck your bean (it can be any bean – a broad bean or a runner bean) between the glass and the tissue. 

3) Fill with plenty of water. You want the tissue to wet, but you don’t want the bean to swimming in water – in case it gets mouldy.

4) Place your glass in a dark place and to see what happens.

Now wait and make sure the towel stays moist!
