Many plants belong to one big group.
You can find them in many places. They grow in cold and hot lands. We eat fruits like apples and berries. Some even make wood for chairs. They are very helpful to us. Do you like eating fruit?
Many plants belong to one big group.
This group has many kinds of plants. You might know some of them. Roses are in this group.
Many of these plants grow food. You can eat apples and pears. You can also eat berries.
Some plants in this group grow in many lands. They grow in hot places. They also grow in cold places.
Some plants even make wood. This wood can make nice chairs. These plants are very useful to us.
Rosales is a large group of flowering plants. It has about 7,700 different species. These plants grow in many places. You can find them in the mountains. They also grow in the tropics and the arctic.
Many of these plants are very useful. The rose family is called Rosaceae. This family includes many foods we eat. You might eat apples, pears, or plums. Strawberries and raspberries are also in this family. Some people use roses to decorate gardens. Roses are even used in poems and books.
Other plants in this group make important things. The mulberry family is called Moraceae. Mulberry leaves feed silkworms. These worms make silk. Fig trees also belong to this family. Some figs make a juice called ficin. This can kill tiny worms in animals.
Some plants in this group use wind to pollinate. This is the way they make new seeds. This happens for many families in Rosales. This includes the elm family and the nettle family.
Other plants are used for many jobs. The cannabis plant has been used for a long time. People use it for hemp. Some people use it as a drug.
Rosales is a large group of flowering plants. It includes about 7,700 different species. These plants belong to nine different families. There are about 260 genera in this group.
You can find these plants in many places. They grow in the mountains and the tropics. They even grow in the arctic. Different families live in different parts of the world.
Many of these plants have a special way to make seeds. This is called wind-pollination. Most families in Rosales use the wind for this task. This includes the elm family and the nettle family. The mulberry family also uses the wind. This helps the plants spread and grow new life.
Scientists have studied how these plants are related. They use DNA sequences to understand their history. This is part of a system called the APG III. This system shows nine families in the order. These are Cannabaceae, Dirachmaceae, Elaeagnaceae, Moraceae, Rhamnaceae, Rosaceae, Ulmaceae, Urticaceae, and more. Older systems like the Cronquist system were different. They did not group these families the same way.
Some families in Rosales are very important for food. The rose family is called Rosaceae. It has 91 species out of 4,828 in its group. This family includes apples, pears, and plums. You can also find peaches, cherries, and apricots here. Strawberries, blackberries, and raspberries are also in this family. Many people grow these for fruit.
The Moraceae family is also very important. It produces figs, mulberries, and breadfruit.
These plants do many other jobs for people. Mulberry leaves provide food for silkworms. These worms are used to make silk. Some cherry wood is used to make fine furniture. The cannabis plant has been used for many years. People use it for hemp or as a drug. Some fig trees have an enzyme called ficin. This enzyme can kill roundworms in animals.
Rosales is a large order of flowering plants. It includes approximately 7,700 different species. These plants are divided into nine distinct families. They also belong to about 260 different genera. This group is very important to humans. It includes many plants we eat every day. It also includes plants used for medicine and industry.
Scientists use DNA sequences to study these plants. This process is called phylogenetic analysis. It helps researchers understand how different species are related. The Angiosperm Phylogeny Group uses these studies to classify plants. Their APG III system is a modern way to organize them. This system shows that Rosales is monophyletic. This means all the plants in the order share a common ancestor.
In the past, classification systems were different. The Dahlgren system placed Rosales in a group called Rosiflorae. The older Cronquist system was often polyphyletic. This means it grouped plants together that did not share a direct ancestor. In that system, the Rosaceae family was grouped with 23 other families. Most of those families are now placed in different orders. Modern science has corrected these older groupings using genetic data.
Today, the APG III system recognizes nine specific families in Rosales. These include Cannabaceae, which is the hemp family. There is also Dirachmaceae and Elaeagnaceae. The Moraceae is the mulberry family. Rhamnaceae is the buckthorn family. Rosaceae is the rose family. Ulmaceae is the elm family. Finally, Urticaceae is the nettle family.
Researchers have found that Rosales is divided into three clades. A clade is a group of organisms that includes a common ancestor. The first clade is basal and contains the Rosaceae family. The second clade contains four families, such as Rhamnaceae. The third clade consists of the four urticalean families. This order is also a sister to a group containing Fagales and Cucurbitales.
Many Rosales species use wind-pollination. This is a process where the wind carries pollen to other plants. This method is used by families like Moraceae, Ulmaceae, and Urticaceae. These plants can be found almost anywhere on Earth. They grow in the mountains and the tropics. They even grow in the arctic. However, specific families usually prefer certain geographical locations.
The Rosaceae family is very economically important. It contains 91 species out of 4,828 in its group. This family produces many fruits like apples, pears, and plums. It also includes peaches, cherries, and apricots. You can find strawberries, blackberries, and raspberries here too. Many people also grow ornamental roses from this family. Modern rose varieties come from complex hybrids of wild species from Eurasia.
Other families provide unique resources. The Moraceae family produces figs, mulberries, and breadfruit. Mulberry leaves are used to feed silkworms for silk production. Some cherry wood, like from the black cherry, is used for furniture. The cannabis plant has been used for hemp and medicine for millennia. Some fig trees contain an enzyme called ficin. This enzyme can kill roundworms in the intestines of animals.
