Question:

What colour is a dicot?

Clue:

There are 175,000 species of them, so this is something everyone should really know.

Forfeit:

(I can't think of anything witty and clever – or indeed a really smart way of phrasing the question – perhaps someone else can).

Answer:

Pretty much any colour. Most flowers are dicots.

Notes:

Most common garden flowers, shrubs, trees and broad-leaved flowering plants such as magnolias, geraniums, hollyhocks and roses are dicots. About 50% of dicot species are trees.

Dicots is the commonly used shorthand name for dicotyledonous plants, the larger of the two great groups of flowering plants. The other is the monocots – or monocotyledonous – plants.

Lilies, orchids, irises, palms and grasses are monocots.

The word cotyledon is Latin, from the Greek kotuledon, a cup-shaped hollow -such as the suckers of an octopus or the socket of a hip-joint. This comes in turn from kotule, a cup.

Kotule, was also used, in ancient Greek, as 'cup' is in English, to mean a measure – ie a cupful – in ancient Greece this amounted to just under half a pint.

Answer: Bunch of lovely DICOTS (specially shot?)

Technical details:

Flowering plants are technically known as angiosperms. Dicots are technically known as Magnoliopsida; monocots as Liliopsida.

Dicots are usually (but not always) characterized by a pair of seed leaves – or 'cotyledons' –in the embryo inside the seed. They also usually (but not always) have flower parts – sepals, petals, stamens etc – based on a plan of four or five, or multiples thereof.

Cotyledon was the Latin word for the navelwort or pennywort and is sometimes still so used in English.

Intended to follow a question about Didcot. If there isn't a question about Didcot it's obviously not really worth doing.
