Indiana Category 6 Industrial Weed
Management Final Review Exam All
Answered Correct.
Leaves - Answer perform photosynthesis (sugar production) and gas exchange
Cuticle - Answer a protective coating on leaves
Stems - Answer provide support, some photosynthesis, and food storage
Stolon’s - Answer horizontal stems running on the soil surface
Rhizomes - Answer underground horizontal stems
Roots - Answer offer anchorage, water, and nutrient uptake, and food storage
Xylem - Answer moves water and soil nutrients from the roots to the leaves
Pholem - Answer transports sugars that are manufactures in the leaves during photosynthesis,
primarily downward to the roods
Cambium - Answer the plant tissue responsible for growth
Benefits of vegetation management on rights-of-way - Answer to keep weeds clear of signals,
signs, crossroads, and other cars; to allow for inspections in ROW's; to minimize fire hazard; to
reduce power and communication interruptions; and improve drainage
Grasses - Answer plants with narrow, up-right leaves with parallel veins, stems that are hollow
and jointed, and fibrous root systems
Broadleaves - Answer plants with non-parallel leaf margins and non-parallel leaf veins, with
coarse root systems (often with a noticeable tap-root)
, Trees - Answer broadleaf plants that produce persistent, woody tissue on branching, erect
stems. This plant usually has a main stem (trunk), and grows more than 10 feet.
Brush - Answer broadleaf plants that produce persistent, woody tissue on branching, erect
stems. This is a woody plant with multiple stems that grow less than 10 feet high.
Ferns - Answer seedless plants that spread by spores and prefer moist soils.
Annual plants - Answer plants that complete their life cycle in one year
Biennial plants - Answer Plants that complete their life cycle in two growing seasons. Best
controlled during the first year.
Perennial plants - Answer Plants that complete all four growth stages in the first year, then
repeat the vegetative, reproductive, and maturity stages for several years following. Best
controlled as seedlings.
Simple Perennials - Answer spread by seed, and cut root segments
Creeping Perennials - Answer spread by stolons, rhizomes, or by seed
Bulbous perennials - Answer reproduce from underground bulbs or tubers (they also produce
seed)
Weed Growth Stages - Answer 1. Seedling
2. Vegetative
3. Reproductive
4. Maturity
Seedling - Answer a young plant that has germinated from the seed and emerged above the
soil surface (cuticle is thin here, permits easy management)
Vegetative - Answer rapid growth of roots, stems, and leaves (herbicide easily circulates
through the plant at this stage)
