Roots, Stems, and Leaves ï§ In vascular plants, a system of vascular tissue reinforced by lignin distributes materials through leaves, stems, and roots of sporophytes â¢ Xylem: Distributes water and mineralsâ¢ Phloem: Distributes products of photosynthesis.
Hereâs the scenario: * Gutter guards were placed below a downspout that feeds from an upper-roof onto a first floor roof surface with asphalt shingles. This is the sole downspout for a roof section that is approximately 300 square feet. The building on which the guards were tested is 3-stories.
The companies that sell these products play upon the frustration the average homeowner experiences when faced with the periodic cleaning one has to do several times a year to keep gutters clean. It is not uncommon for a homeowner to get a price of $2,000 to $3,000 to install gutter guards on the average home. The pricing varies from region to region, and the type of system being installed.
