Nicotiana sylvestris

Nicotiana sylvestris is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nicotiana sylvestris rather than just read about it. In short: Nicotiana sylvestris is a species of flowering plant in the nightshade family Solanaceae, known by the common names woodland tobacco, flowering tobacco, and South American tobacco. It is a biennial or short-lived perennial plant in the tobacco genus Nicotiana, native to the Andes region in Argentina and Bolivia, in South America.

Key takeaways

  • Nicotiana sylvestris belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Nicotiana sylvestris to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Nicotiana sylvestris from memory before moving on to harder problems.

Reference excerpt

Nicotiana sylvestris is a species of flowering plant in the nightshade family Solanaceae, known by the common names woodland tobacco, flowering tobacco, and South American tobacco. It is a biennial or short-lived perennial plant in the tobacco genus Nicotiana, native to the Andes region in Argentina and Bolivia, in South America.

Description It is a tall plant, growing to 1.5 m (4.9 ft) high by 0.5 m (1.6 ft) broad. The leaves are simple, somewhat sticky, with the blade partially surrounding the stem, clasping petiole. Flowers are produced on many-branched stems. The flowers are tubular, white, borne in racemes held above the foliage. Flowers can be over 7 cm long with a face 2 cm wide. Their intense scent is strongest at night, to attract pollinating moths. Each flower eventually produces a large quantity of small seeds. This plant is thought to be one of the parents of Nicotiana tabacum, the plant used in modern tobacco production. However, all parts of N. sylvestris can cause discomfort or irritation if consumed.

Cultivation Nicotiana sylvestris is cultivated as an ornamental plant as it has fragrant and visually interesting flowers. While most Nicotiana species and members of the Solanaceae family are naturally short-lived perennials, Nicotiana sylvestris is typically cultivated as a half-hardy annual in cold climates. Gardeners usually start seeds indoors under heated conditions in early spring, then transplant seedlings outdoors once frost danger has passed. In Great Britain, this plant can only survive winter outdoors in particularly sheltered coastal regions or select London neighborhoods where temperatures remain above −5 °C (23 °F). Cultivars of this plant have gained the Royal Horticultural Society's Award of Garden Merit.

Worked examples

Example 1 — a first encounter with Nicotiana sylvestris

Start with the simplest possible case. Write down what Nicotiana sylvestris claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nicotiana sylvestris before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nicotiana sylvestris ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nicotiana sylvestris

In research
Nicotiana sylvestris appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Nicotiana sylvestris in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Nicotiana sylvestris is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biennial plants, Flora of Argentina, Flora of Bolivia, so understanding it makes those chapters shorter.
In everyday life
Look for Nicotiana sylvestris outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
