Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the lemon, relay botany, cultivation, uses and nutrition from horticulture and food sources, note skin and dental cautions, and distinguish lemons from limes, citrons, Meyer lemons and rough lemons.

The lemon, a small evergreen citrus tree and its yellow oval fruit, botanically Citrus x limon, a hybrid of citron and sour orange, grown in warm temperate and subtropical regions for its acidic juice rich in citric acid and vitamin C, its aromatic peel and essential oil, and its use in food, drinks, cleaning and traditional remedies; major producers include India, Mexico and Argentina. Lemons are safe foods but their acidity can erode tooth enamel and irritate reflux, and lemon peel oil with sun exposure can cause phytophotodermatitis, a skin reaction.

What it is for: Food, flavouring, cleaning and vitamin C source.

It can be explain botany and cultivation; relay culinary and other uses; relay nutrition; note skin and dental cautions.
