Dicotyledons are a group of plants that belong to the class Magnoliopsida (dicots flowering plants). They get their name from the presence of two cotyledons in the embryo. This group includes more than 250 thousand plant species, which accounts for about 70% of all plant species.
One of the main characteristics of dicotyledonous plants is the presence of true leaves, stems and roots. They also have more complex flower structures than monocots. Additionally, dicotyledons are the largest group of vascular plants that have vessels for the transfer of water and nutrients.
Dicotyledons can be divided into two groups: true dicots and non-standing dicots. True dicotyledons have two cotyledons in the embryo, while non-standing dicotyledons have only one cotyledon.
Among the true dicotyledonous plants, several classes can be distinguished, such as the magnolia, rose, gentian, cruciferous and many others classes. Each of these classes has its own characteristic features that allow botanists to identify them.
Dicotyledonous plants play a huge role in human life. They are used in the food industry, medicine, cosmetology and many other industries. For example, many of the vegetables and fruits we eat are dicots. Moreover, many medicinal products are also produced from dicotyledonous plants.
In addition, dicotyledonous plants are of great ecological importance. They are the planet's main source of oxygen and play an important role in combating climate change. They also provide shelter and food for many species of animals.
Thus, dicotyledonous plants are an important element of our world and play a huge role in the life of humans and nature as a whole. They present an amazing variety of shapes and colors that continue to delight and inspire us with their beauty and complexity.
