What is complex tissue?
Complex tissue is composed of more than one kind of cells. The complex tissues are generally heterogeneous in nature, being composed of dissimilar types of cell elements. They are two types, namely Xylem tissue and Phloem tissue. Xylem is a multifaceted tissue forming a part of the vascular bundle.
Which tissue is composed of more than one kind of cells?
Complex tissue is composed of more than one kind of cells. They are two types, namely Xylem tissue and Phloem tissue. Complex tissue: Complex tissue is composed of more than one kind of cells.
What are the functions of xylem and phloem tissue?
Functions of xylem tissue: Theirfunctions are to give mechanical strength to the plant body, conduction of water, minerals and food materials and storage of food. ii. Phloem tissue: Phloem tissue consists offour types of cells, namely: sieve tubes, companion cells, phloem fibres and phloem parenchyma.
What are the functions of vascular tissue?
They are conducting tissue and called as vascular tissue. 1)Tracheids:They help in transport of water and minerals vertically. 2)Vessels:They help in transport of water and minerals vertically. 3)Xylem parenchyma:They store food,helps in sideways conduction of water.
What is complex permanent tissue and its function?
Complex permanent tissue is defined as a collection of structurally dissimilar cells performing a common function or set of functions. They are made up of more than one type of cells. They are of two types xylem and phloem. Xylem is the chief water conducting tissue of the plants.
What are the complex tissues?
Those tissues that are made up of structurally different types of cells that are involved in the related functions are called complex tissues. Xylem and phloem are the complex tissues. Xylem is made up of vessels, tracheids, xylem parenchyma, and xylem fibers.
What are complex tissue give an example?
A tissue is a group of cells having similar structure, function and origin. So complex tissues are having different types of tissues with similar function. In plants vascular tissues (xylem and phloem) are one of the examples of complex tissues.
Where are complex tissue found?

What is complex tissue Short answer?
complex tissues are made up of more than one type of cells. Parenchyma, collenchyma and sclerenchyma are examples of simple plant tissue, whereas xylem and phloem are examples of a complex tissue.
What is simple complex tissue?
Simple tissues are those which consist of one kind of cell. Complex tissues are those which contain different kinds of cells within a single tissue as they perform a definite function altogether. Simple tissues consist of parenchyma, collenchymas, and sclerenchyma whereas complex tissue consists of xylem and phloem.
What is the structure of complex tissues?
The complex tissues are heterogeneous in nature, being composed of different types of cell elements. The latter remain contiguous and form a structural part of the plant, adapted to carry on a specialised function. Xylem and phloem are the complex tissues which constitute the component parts of the vascular bundle.
What do you mean by complex tissue class 11?
As we already mentioned, complex tissue is a group of more than one type of cell which works together as a unit. - The main function of complex tissue in plants is transportation of organic material, water, and minerals. - They are also known as conducting or vascular tissue.
Is blood a complex tissue?
Despite looking like a simple red fluid, blood is as complex as any tissue in the body.
What is complex tissue class 9?
A complex tissue of the plants consists of more than one type of cells which work together to perform a particular function. Biology. Standard IX.
What is complex tissue 9 Samacheer Kalvi?
Answer: Complex tissues are made of more than one type of cells that work together as a unit. Complex tissues consist of parenchyma and sclerenchyma cells. Common examples are xylem and phloem.
What are the types of complex permanent tissue?
Complex permanent tissue (conducting tissue) - Xylem They are of two types xylem and phloem.
What is the function of complex tissues?
Complex tissues perform the duty of conduction of raw food materials to leaves and prepared food materials to all the living cells. Beside preparation of food, water is necessary for various reactions. This water is conducted from root to stem through the complex tissue named xylem.
What is the function of Xylem fibre?
Xylem fibre: These are sclerenchymatouscells. Their main function is to give mechanical strength to the plant.
What are the four types of Xylem tissue?
i. Xylem tissue: Xylem tissue consists of four types of cells, namely: Tracheids, Vessels or Trachaea, Xylem fibre and Xylem Parenchyma.
What are companion cells?
Companion cells: These are parenchymatous, narrow, elongated cells, andare closely associated with the sieve tube. They have dense cytoplasm and a large nucleus. Conduction with the sieve tube is done through the pores present on the walls of these cells. They help the sieve tubes in conduction of food materials.
What are the functions of xylem parenchyma?
Their main function is to give mechanical strength to the plant. Xylem parenchyma: These areparenchymatous .cells. Functions of these cells are storage and conduction of food materials. Functions of xylem tissue: Theirfunctions are to give mechanical strength to the plant body, conduction of water, minerals and food materials and storage of food.
What is the function of a phloem?
Function of Phloem tissue: There main function is to conduct food materials, prepared in the leaves, to different parts of the plant. They give mechanical strength to plant organ. In case of necessity they store food materials.
What are the functions of tracheids?
Cell walls are hard, strong. and lignified. Their main functions are to gIve mechanical strength and to supply water and dissolved minerals from root to the leaves.
What is the protective tissue found in plants?
Sclerenchyma is a kind of protective tissue found in plants. Sclerenchyma is a thick, lignified secondary walls which are seen throughout all plant tissues.
What are the two types of vascular tissues?
Xylem and Phloem are two different types of vascular tissues, which are mainly involved in the transportation process. These tissues form a vascular bundle and these work together as a unit.
