Vascular Plants
Vascular plants are those plants that possess specialised vascular tissues for the transport of water, minerals, and food. These plants contain xylem for transporting water and minerals from the roots to other parts of the plant, and phloem for transporting food from the leaves to other parts of the plant.
Vascular plants have a diploid sporophyte stage as the dominant phase in the lifecycle. They contain true roots, stems, and leaves.

Classification and Examples
Vascular plants, also known as tracheophytes, are grouped under the subkingdom Tracheobionta of the Plant Kingdom.
Tracheobionta includes pteridophytes and all the seed-bearing plants called spermatophytes. Spermatophytes contain gymnosperms and angiosperms.
Vascular plants, such as [pteridophytes], gymnosperms, and angiosperms, possess conducting tissues, while bryophytes do not.
Vascular Tissues
Vascular plants contain specialized conducting tissues known as xylem and phloem. These tissues are a type of complex tissue, and their arrangement and structure differ amongst different categories of vascular plants, such as pteridophytes, gymnosperms, monocots, and dicots. In roots, stems, and leaves, xylem and phloem are arranged together as a vascular bundle.
In Angiospermic plants, the most primitive and simple arrangement of vascular tissues is the Protostele type, where xylem is present in the middle surrounded by phloem tissues. In contrast, the vascular bundles of the root and stem are arranged radially and conjointly, respectively. In the root, xylem and phloem are arranged alternately, with the pith in the centre. In the stem, xylem and phloem are present at the same radius, with the pith in the centre. Additionally, in dicot stems, the cambium is found between the xylem and phloem, and is responsible for secondary growth.
Xylem
Xylem in angiosperms transports water and minerals from roots, and is made up of tracheids, vessels, xylem parenchyma and xylem fibres. Tracheids and vessels are the main conducting tissues, while in pteridophytes and gymnosperms, tracheids are the main water-conducting tissues and vessels are absent.

Phloem
Phloem in angiosperms is composed of sieve tube, companion cells, phloem parenchyma and phloem fibres, and is responsible for transporting food produced during photosynthesis to other parts of the plants. Pteridophytes and Gymnosperms, however, lack sieve tubes and companion cells; Gymnosperms instead contain albuminous cells and sieve cells, and Monocots lack phloem parenchyma.
The vascular system of vascular plants consists of xylem and phloem, which are bundled together to form a vascular bundle. These conducting tissues can be arranged in various ways.
Frequently Asked Questions
What are Vascular Plants?
Vascular plants are plants that contain specialized tissues for the transport of water, minerals, and other nutrients. They are also known as tracheophytes and include ferns, conifers, and flowering plants.
Vascular plants are a large group of plants that possess lignified tissues known as xylem, which are responsible for transporting water and nutrients throughout the plant. Additionally, they also have non-lignified phloem to transport food produced during photosynthesis.
What is Xylem?
Xylem is a tissue in plants that transports water and nutrients from the roots to the leaves.
Xylem is one of the vascular tissues present in vascular plants. It is responsible for transporting water from the roots to the leaves and stems, as well as nutrients. The conducting cells of the xylem are the vessel elements and tracheids, while other cell types include xylem fibres and xylem parenchyma.
Phloem is the tissue in plants that helps to transport food and other nutrients from the leaves to other parts of the plant.
Phloem is a type of vascular tissue found in vascular plants. It is responsible for the transport of soluble organic compounds (such as sugars) to other parts of the plant through a process called translocation. The conducting cells of the phloem are composed of phloem parenchyma, sieve elements, companion cells and phloem fibres.
