Some plants are in a big group. They grow in many places. Some of these plants are food for us. They are also food for bugs. These plants are very special. Can you find a bean plant?
Some plants belong to a big group.
This group has many types of plants. Most of them are in the bean family. This family is very large. It is the third largest plant family.
Some plants in this group are food.
Other plants are food for bugs. Some moths and butterflies eat them.
These plants grow all over the world.
Some parts grow in the north. They split from other plants long ago. It is a very old group of plants.
Fabales is a big group of flowering plants.
This group has many different plant families. Most of these plants belong to the Fabaceae family. We also call these plants legumes. This is the third largest plant family on Earth.
Scientists study the Fabales very closely. They study the Fabaceae because they are food plants. They are also very diverse. This means they have many different types. Other plants in the group are also important. Some plants in the Polygalaceae family are food for bugs. These bugs include moths and butterflies.
These plants grow in many places around the world.
Some parts of this group grow in the north. Scientists use special tools to study how they are related. This is called molecular phylogeny. This is a way to study plant history using tiny parts.
This group of plants is very old. They split from other plants a long time ago. This happened about 101 million years ago.
Some plant families in this group are still being studied. We do not know everything about them yet.
Fabales is a large group of flowering plants.
This group includes many different plant families. Most of these plants belong to the Fabaceae family. People also call these plants legumes. This is the third largest plant family on Earth. It is a very important group of living things.
This group works in many different ways. The Fabaceae family has three subfamilies. These are called Caesalpinioideae, Mimosoideae, and Faboideae. The order also includes the Quillajaceae family. Other families in the group are Polygalaceae and Surianaceae. The Polygalaceae family includes milkworts. Some of these plants are food for moths and butterflies.
Scientists have used different ways to name these plants. The APG II system is one way to group them. In this system, Fabales includes four main families. The Cronquist system is another way. Under that system, Fabales only had the Fabaceae family. The Dahlgren system put them in a group called Fabiflorae. This shows how our ideas about plants can change.
There are many facts about the history of these plants. Scientists use a molecular clock to find out how old they are. This tool helps them see when plants split apart. The Fabales split from other plants about 101 million years ago.
Most research focuses on the Fabaceae family. This is because they are very diverse. They are also very important as food plants.
You can find these plants in many places. They are a cosmopolitan order of plants. This means they grow all over the world. One specific group called Papilionoideae grows in the north. This is part of the North Temperate Zone. Scientists use molecular phylogeny to study them. This is a way to look at tiny parts to see how plants are related. They are still learning about the Quillajaceae and Surianaceae families.
Fabales is a large order of flowering plants. These plants belong to the rosid group of the eudicots. Scientists use different systems to classify these living things. The Angiosperm Phylogeny Group II, or APG II, is one such system. In this classification, Fabales includes several distinct plant families. This order is important because it contains many plants used for food. It also includes plants that support various insect species.
The structure of the Fabales order depends on the classification system used. Under the APG II system, the order includes four main families. The first is Fabaceae, which are also known as legumes. This family contains three subfamilies: Caesalpinioideae, Mimosoideae, and Faboideae. The second family is Quillajaceae. The third is Polygalaceae, which are often called milkworts. This family includes the groups Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae. Finally, the order includes the Surianaceae family.
Different scientists have organized these families in different ways over time. The Cronquist system used a much narrower definition. Under the Cronquist system, the Fabales order contained only the Fabaceae family. Other families were placed in different orders entirely. For example, Cronquist put Polygalaceae in its own order called Polygalales. He also placed Quillajaceae and Surianaceae within the order Rosales. The Dahlgren system used a different name for this group. He placed them in a superorder called Fabiflorae, or Fabanae.
Research into these plants focuses on different areas based on their diversity. Most scientific study focuses on the Fabaceae family. This is because Fabaceae is the third-largest plant family in the world. It contains the majority of the diversity found within the Fabales order. These plants are also highly significant because they serve as food plants. The Polygalaceae family is also well researched. This is due to the large diversity found in the genus Polygala. Many members of this family are food sources for Lepidoptera. This term refers to butterflies and moths.
Scientists use molecular phylogenetic techniques to understand how these plants are related. This method looks at genetic relationships to build a family tree. While these techniques provide strong support for the existence of the Fabales order, some mysteries remain. Taxonomists are still studying the morphological relationships of certain families. This means they are looking at the physical shapes and structures of the plants. Specifically, they are studying how Quillajaceae and Surianaceae relate to the rest of the order. This research is limited because there is not yet much data on these two families.
We can use history to understand when these plants first appeared. Scientists use a method called molecular clock calculations to estimate time. This helps them determine when different lineages split apart. According to these calculations, the lineage for Fabales split from other plants about 101 million years ago. This long history has allowed the order to spread across much of the planet. The Fabales are described as a cosmopolitan order. This means they are found in many different parts of the world.
Even though the order is widespread, some groups have specific homes. The subfamily Papilionoideae, which is part of the Faboideae subfamily, has a unique distribution. It is well dispersed throughout the northern part of the North Temperate Zone. This shows how different parts of the Fabales order occupy different environments. Studying these patterns helps scientists understand how plants move and grow across the Earth. The study of Fabales connects botany to history, genetics, and ecology.
