Lilies, tulips, orchids, bluebells, crocuses, amaryllis and daffodils all belong to the monocot class. Monocots can be identified by the number of parts of the flower, with petals or stamens found in numbers divisible by three.
Flowering plants have been divided into two major groups: monocots and dicots. Monocots have fibrous root systems that spread out in hundreds of small individual roots, which can sometimes be visible near the surface of the soil at the plant's base. Leaf veins in monocots typically run parallel along the length of the leaf, while those of dicots branch out from larger central veins. Monocots, for the most part, cannot create wood or bark.
There are also types of plants that ignore some of these rules, such as Potamogeton, or pondweed, which has flower petals in multiples of four. Water lilies have vascular tissue similar to monocots, but are classified as a dicot. Monocots, such as the order Dioscoreales, use the central leaf vein structure like dicots.
Some plants have unusual flower structures, such as grasses and cattails. Both are monocots that produce flowers but do not have sepals or petals. Oak, maple and sycamore trees are also considered dicots, as they produce flowers, while palm trees are classified as monocots due to their root structure and layers of leaf bases. Flowers, such as roses, daisies, hollyhocks, foxgloves, marigolds and begonias, belong to the dicot class.
