A specialized network of vessels for the circulation of fluids throughout the body tissues of an animal. All animals, apart from simple invertebrate groups, possess a blood vascular system, which enables the passage of respiratory gases, nutrients, excretory products, and other metabolites into and out of the cells.

What is the function of vascular tissue?
The vascular tissues of plants, which are composed of specialized conducting tissues, xylem and phloem, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.
How is vascular tissue adapted to its function?
The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube. They become strengthened by a substance called lignin . Lignin gives strength and support to the plant.
What does vascular mean in animals?
Relating to, characterized by, or containing cells or vessels that carry or circulate fluids, such as blood, lymph, or sap, through the body of an animal or plant.
What is vascular system in plants and animals?
A vascular system simply means that it is a system where things are transported in vessels. For plants, it will be the xylem and phloem and for animals, it will be the arteries and veins.
How do animal and plant tissues perform their roles?
Cells which are similar in structure group together to form tissues performing a particular function. Tissues form organs which combine to allow organisms to exist. Plant and animal cells have structures related to their functions. Plant tissues are broadly divided into Dividing or Meristematic and Permanent tissues.
What is the main function of vascular tissue class 9?
Vascular tissues in plants perform the function of transport. The xylem tissue transports—(i) water and dissolved minerals from roots to various parts plant body. While the phloem transports prepared food material from leaves to different plant parts.
What is the significance of vascular tissues in stem?
Vascular tissue is present in the largest quantity in the stem and root of woody plants, as xylem and phloem, and is known mostly for its functions of transporting water and nutrients within the plant and providing mechanical support.
Is xylem alive or dead?
Xylem consists of dead cells (parenchyma is the only living cells present in the xylem). Pholem mainly contains living cells (fibres are the only dead cells in the phloem). They comprise of xylem vessels, fibre and tracheids. ... Xylem is the dead tissue at maturity, but no cell contents.
Is vascular tissue an adaptation?
Seedless vascular plants (lycophytes, ferns, and horsetails) have two major adaptations compared to nonvascular plants: true roots and vascular tissue. These adaptations allowed seedless vascular plants to outcompete nonvascular plants in early colonization of life on land.
Do aquatic animals have circulatory system?
Animals live in an aquatic environment even on land. Most animals have open circulatory systems. ... Those few animals with closed circulatory systems have a continuous series of vessels to circulate fluid to the vicinity of all cells, whereas those with open systems have vessels only near the heart.
Which tissue has no vascular supply?
Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels.
What is the difference between vascular and avascular tissue?
Vascular tissues in the human body have blood vessels like veins, arteries and capillaries, while avascular tissues do not. For example, muscle tissue is vascular, or vascularized. ... Cartilage is another type of avascular tissue.
How are vascular systems in plants and circulatory systems in animals the same and how are they different?
How are the circulatory system in animals and the vascular system in plants different from each other? The circulatory system transports blood around the body. The vascular system has two parts. Xylem transports water and minerals up, and phloem transports sugar down and to all the cells of the plant.
How are the circulatory systems in animals and plants alike?
Similar Systems:
The circulatory system of animals is made up of the heart and blood vessels known as arteries, veins, and capillaries. The circulatory system of plants consists of vessels called xylem and phloem that run throughout the tissue.
What are the animal tissues?
The tissues of multicellular, complex animals are four primary types: epithelial, connective, muscle, and nervous. Recall that tissues are groups of similar cells group of similar cells carrying out related functions.
