Different cells in our body carry out different functions even though all the cells in our body contain the entire dna code. why do only certain cells produce specific proteins? a. because gene expression is a regulated process b. because the dna is arranged differently in different cells c. all cells produce the same proteins d. because the dna is not the same in all cells

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.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
