Q.Students were on the excursion to a botanical garden. They noted following observation. Will you be able to help them in understanding those conditions? Students observed large leaves of coconut and small leaves of Mimosa. Teacher asked it what way they are similar?

Compare leaf structure (whether the lamina is divided into leaflets) rather than overall …

• Judging similarity/difference purely by leaf size instead of by whether the leaf is simple or compound. …
