Do you find new leaves growing on the plant? Do the colours of the leaves change as they grow larger?
New leaves grow on plants throughout the year.
Young leaves often have a different colour (lighter green, reddish, or copper-coloured) compared to mature leaves. As leaves grow larger, their colour changes to a darker green.
This colour change happens because the chlorophyll content increases as the leaf matures.
Explanation
The chapter mentions that leaves of different plants have different colours, shapes and sizes. The activity encourages students to observe colour changes in leaves as they grow.
