Vascular plant

Vascular plants, also called tracheophytes, are plants that have special parts to move water, minerals, and food inside them. These plants have tissues called xylem, which carry water and minerals from the roots to other parts of the plant. They also have a tissue called phloem, which moves food made by photosynthesis, like sugars, from the leaves to other parts of the plant.

These plants include groups like clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms, which are flowering plants. Vascular plants are most land plants, with around 300,000 known types. They are different from nonvascular plants like mosses and green algae, which do not have these special tissues.

In the past, vascular plants were sometimes called “higher plants” because people thought they were more advanced due to their complex structures. But this idea came from an old belief, and scientists do not use that term anymore. Today, we know that all plants have their own special ways of growing and living.

Characteristics

Vascular plants have special tissues that help move water, minerals, and food through the plant. These tissues are called xylem and phloem. The xylem carries water and minerals from the roots to other parts of the plant. The phloem carries food made during photosynthesis from the leaves to the rest of the plant. These tissues let vascular plants grow larger than non-vascular plants, which do not have these special tissues.

Most vascular plants have true roots, leaves, and stems. Their main life stage is the sporophyte, which makes tiny particles called spores. This is different from non-vascular plants, whose main life stage makes cells called gametes. These features help vascular plants grow in many places on Earth.

Phylogeny

Scientists study how different types of vascular plants are related. They use a diagram called a phylogeny to show these relationships. This helps us learn which plants share the same ancestors.

Some researchers think that groups of plants, like ferns, might not all come from one common ancestor. Different studies can sometimes show different ideas about these relationships.

Nutrient distribution

Water and nutrients are pulled up from the soil by the roots. Special parts inside the plant move these. The xylem carries water and minerals. The phloem moves sugars made by leaves during photosynthesis.

The xylem is made of dead, hollow cells that form tubes. The phloem has living cells that carry sugars and other important materials. These parts work together to help the plant grow and stay healthy.
