LESSON CONTENT
CHANGES IN PLANT
Plants are also living things, they experience changes too as they grow. Most changes in plants are permanent changes.


Using Maize as an Example.
When a maize seed is planted into the soil, after some time, we experience change as the seed begins to grow, it changes from seed to seedlings. We experience increase in growths and the leaves keep broaden itself and greenish in colour, this is another change, after some time it will start producing fruits and the leaves of the corn turns yellow and brown before it is harvested by the farmer. These are different changes in plant.
