Diagram of cell wall & flagellum of Gram- bacteria

Diagrammatic representation of the cell wall, cell membrane, and a flagellum of a Gram-negative bacterium. Gram-negative bacteria have an outer lipopolysaccharide layer (above, yellow), as an outer membrane to the cell wall. Beneath it is the peptidoglycan cell wall, rigid & protective, made of sheets of glycan (sugar, white bricks) with peptide cross-links. The true cell membrane is at bottom (yellow, phospholipid). Pathogens attach to both membranes, molecules diffuse through, & anti- gens are found on them. The rotor mechanism of a flagellum is portrayed (red and blue); it rotates the flagellum like a propeller for movement

Japanese knotweed

Japanese knotweed (Fallopia japonica) growing rapidly after being cut back. Japanese knotweed is a tough, highly invasive perennial, that was introduced to this country by the Victorians. It grows to two to three metres high every spring, often crowding out native species, its roots grow at least as deep. It is incredibly hard to kill, as less than one gram of living rhizome, a horizontal underground stem, is needed to regenerate a plant. There are few chemicals that can destroy the plant, and biological control, the use of introduced fungi or insects, is now being considered in the UK. It is now illegal to plant Japanese knotweed in the UK
