Plants with just one cotyledon are said to be monocotyledons. They also include floral segments that are multiples of three. This implies that their blooms may be made up of sepals instead of petals, or they may have three, six, or nine petals. Additionally, they have accidental roots. These are roots that may sprout from nearly any portion of the plant that comes into touch with the soil, such as the stem.
For instance, garlic plants, spiderwort, etc.
