When you are working with chemicals you should

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.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

the answer is a) cell division.

hope this !
