Each round shows four plants, or four things made from plants. Three of them belong to the group in the question. One does not. You tap the one that does not belong.
The groups cover the whole subject: plant families, the parts of a plant, trees and flowers, fruit and vegetables as botany sees them, where plants grow, and what people make from them.
The traps are the point. The strawberry feels like a berry and is not. The peanut feels like a nut and is a legume. The banana plant feels like a tree and is a herb. Each round ends with one line that explains the answer.
How to play
Each round asks one question, for example "Which of these is NOT in the rose family?".
Read the question. Then tap the option that does not belong.
You get one pick for each round. There are no second guesses.
The quiz marks your answer immediately. It also gives one line that explains the answer.
You start with three lives. The hearts in the top bar show the lives that you have.
A correct answer gives one point. A wrong answer costs one life.
A round that costs a life gives no points. The quiz continues with the next round.
The run ends when you lose the third life. It also ends when you play every round in the run.
Select "Review rounds" on the result screen to see each round that you played.
What counts in this quiz
100 groups from botany and the garden. One run uses 50 of them. The rounds, the options and the impostor are drawn fresh every run, so two runs do not ask the same set of questions.
Every option is clearly in the group or clearly out of it. No round has two possible answers.
Classifications follow standard botany. A tomato is a fruit, a potato is a stem, a mushroom is not a plant.
The Food & Drink quiz owns the kitchen. This quiz asks what a plant is, where it grows and what it is related to.
Your score is the number of correct answers. The maximum score is 50, which is every round in one run.
A wrong answer costs one life. You keep the points that you have.
The timer counts up from your first pick. It only separates equal scores on the leaderboard.
What's not included, and why
Plants that botanists still argue about are not used, on either side of a round. Celery and rhubarb sit out of the stem round, because a cook and a botanist disagree.
No Latin names. Every option is the everyday English name.
No foraging advice. The quiz says which plants are poisonous. It never says which wild plants are safe to eat.
Good to know
The largest flower in the world, Rafflesia, is a parasite with no leaves, no stem and no roots. It smells of rotting meat.
Bamboo is a grass. Some species grow almost a metre in a day.
The oldest known tree is a bristlecone pine in California. It is more than 4,800 years old.
The peanut is a legume that ripens underground. The plant bends its flower stalk down and pushes the pod into the soil.
