Angiosperms are divided into monocots and dicots, which differ in the structure of the embryo. Point by point, consider the features with which it is possible to distinguish monocotyledonous from dicotyledonous plants.
1. Form. If dicotyledonous plants are represented by trees, and bushes, and grasses, then in monocotyledons – mainly herbaceous plants.
2. Cambium (tissue that allows the plant to grow in width). Since monocots do not have woody forms, therefore there is no cambium either. But in woody dicotyledonous species, there is a thick layer of cambium inside the stem.
3. Leaves of plants. Monocots are characterized by simple leaves without a petiole, sessile leaves with parallel or arcuate venation. The dicotyledonous leaves can be simple or complex, with cuttings. The venation is reticulate.
4. Root system. A fibrous root system in monocots, a core system in dicots.
5. Flowers. The number of elements in the flower of monocots is divisible by three, in dicots – four and five. The flowers are dim, small, with a single perianth. Dicotyledons have bright, large flowers with a double perianth.
