AThrees in monocots, fours or fives in dicots
BFours or fives in monocots, threes in dicots
CThrees in monocots, twos or sixes in dicots
DFours in monocots, twos or threes in dicots
Answer & Solution
Correct answer: A. Threes in monocots, fours or fives in dicots
1. The number of sepals and petals depends on whether the plant is a monocot or a dicot.
2. In monocots petals usually number three or multiples of three.
3. In dicots the number is four or five, or multiples of four and five.
4. Reversing the two is the standard error, and it is easy to check against a lily and a rose.
5. No group is described as having a base number of two, so the remaining options can be set aside.
