Final answer:
Monocots have all the following characteristics, except flower parts in threes.
Step-by-step explanation:
Monocots have all of the following characteristics EXCEPT:
- One cotyledon in their seeds
- Vascular bundles in rings
- Vascular bundles throughout the stems
- Flower parts in threes
Monocots are a group of plants that have a single cotyledon in the seedling, and also share other anatomical features. However, one characteristic that they do not have is flower parts that are arranged in threes. Instead, monocots often have flower parts that are arranged in multiples of three or six.
