They can do by realizing the waxy substance which is present in some fruits.

Excretion in Plants
Plants excrete waste products through various parts of their bodies, including leaves and fruits.

Excretion through Leaves:
- Plants excrete excess water and oxygen through tiny openings called stomata on the surface of their leaves.
- They also excrete waste products such as salts, toxins, and excess minerals through these stomata.

Excretion through Fruits:
- Fruits in plants serve as a means of dispersing seeds, rather than excreting waste products.
- However, some fruits may contain substances that serve as a defense mechanism against predators or aid in seed dispersal.
- These substances are not considered waste products in the same way that excretory products are excreted through leaves.
In conclusion, while plants excrete waste products through leaves, fruits primarily serve as a means of reproduction and seed dispersal rather than excretion.
