Look at the picture below and match the letter
to the correct part of the structure.

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.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

the correct answer to this question is #5
