Some elephants in the scrub jungles of africa had long trunks with which to reach out for leaves. they were able to reproduce more successfully than elephants with short trunks. which aspect of darwin's theory is this scenario an example of?

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
