In an experiment similar to the one performed by Benzer, you used the T4 phage rII- deletion mutants A, B, C, D, and E in pairwise infections of the E. coli B strain. You then collected progeny phages and infected the E. coli K strain. Successful infections are indicated by a ( ).

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.
