Primarily‚ phloem carries dissolved food substances throughout the plant. This conduction system is composed of sieve-tube member and companion cells‚ that are without secondary walls. The parent

his door. In this section the "Sieve and the Sand" refers specifically and literally to a passage where Montag had remembered a loathsome memory from his childhood. In the incident from his childhood‚ a cousin challenged Guy Montag to fill a sieve with sand in exchange for a dime. Of course‚ the more sand that Montag put into the sieve the more sand fell through the holes in the sieve. This frustrated Guy and it caused him to cry. Symbolically‚ the sieve represents Montag’s desire to

The standard L.A abrasion test subjects a coarse aggregate sample (retained on the No. 19.0 mm sieve) to abrasion‚ impact‚ and grinding in a rotating steel drum containing a specified number of steel spheres. As the drum rotates‚ a self-plate picks up the sample and the steel spheres‚ carrying them until they are dropped to the opposite site of the

In the second part of the book (Bradbury page 74)‚ Montag has a flashback of when he tried to fill a sieve with sand‚ but the sand seemed to vanish through the sieve. The sand and the sieve is symbolic of Montag’s general struggle to maintain and keep the information that books offer‚ where the information from the books
