Solanales

Solanales 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 Solanales rather than just read about it. In short: The Solanales are an order of flowering plants in the asterid group of the eudicots. Well-known members of Solanales include potatoes, sweet potatoes, eggplants, tomatoes, chili peppers, tobacco, petunias, nightshades, and morning glory.

Key takeaways

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

Reference excerpt

The Solanales are an order of flowering plants in the asterid group of the eudicots. Well-known members of Solanales include potatoes, sweet potatoes, eggplants, tomatoes, chili peppers, tobacco, petunias, nightshades, and morning glory. Some older sources used the name Polemoniales for this order.

Taxonomy The following families are included here in newer systems such as that of the Angiosperm Phylogeny Group (APG):

Family Solanaceae (nightshade family; includes Nolanaceae as well as potatoes, eggplants, tomatoes, chili peppers, tobacco, and petunias) Family Convolvulaceae (morning glory and sweet potato) Family Montiniaceae Family Sphenocleaceae Family Hydroleaceae The APG II classification treats the Solanales in the group Euasterids I.

Under the older Cronquist system, the latter three families were placed elsewhere, and a number of others were included:

Family Duckeodendraceae (now treated as a synonym of Solanaceae) Family Nolanaceae (now treated as a synonym of Solanaceae) Family Cuscutaceae (now treated as a synonym of Convolvulaceae) Family Retziaceae (now treated as a synonym of Stilbaceae, order Lamiales) Family Menyanthaceae (now placed in order Asterales) Family Polemoniaceae (now placed in order Ericales) Family Hydrophyllaceae (now placed in order Boraginales) In the classification system of Dahlgren the Solanales were in the superorder Solaniflorae (also called Solananae).

Worked examples

Example 1 — a first encounter with Solanales

Start with the simplest possible case. Write down what Solanales 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 Solanales 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 Solanales 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 Solanales

In research: Solanales 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 Solanales 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: Solanales is common in secondary-school and first-year university syllabi. It links to neighbouring topics Angiosperm orders, Solanales, so understanding it makes those chapters shorter.
In everyday life: Look for Solanales 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.

Frequently asked questions

What is Solanales in simple terms?

Why does Solanales matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Solanales?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
