Activity 1.3
Take a money plant. Cut a piece of the stem such that it contains a few leaves. Cut another piece
of stem between any two leaves. Dip one end of each piece in water and observe for the next few
days. Which one grows and gives rise to new leaves? What do you conclude from this activity?
R eproduction by Leaves
The leaves of certain plants, such as
bryophyllum, produce buds called
plantlets on their leaf margins. Upon
developing, these buds drop and grow into
new plants when they find moist soil. Begonia
plants also reproduce in this manner. Bryophyllum
R eproduction by Spores
Spores are very small and light structures
in plants like ferns and mosses. In these
plants, new plants grow from these tiny
structures. They can survive for a long
time in even adverse conditions.
Fern
