Additional observations were made on day 21, and no yellow-leaved seedlings were found alive in either dish. This is most likely because

Inability to convert the light energy into chemical energy.

Explanation:

The above question relates to the issue regarding photosynthesis. Plants contain chlorophyll and this helps them in the conversion of the light energy that they get from the sunlight into a chemical energy.

In the case that no yellow-leaved seedlings were found alive in either dish, the reason for this will mainly be because the plant was not able to convert the light energy into chemical energy.

c.more precipitation,but only when emission levels.

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.
