Xylem and phloem are made of different cell types, who come together to perform a common function, hence they are called complex tissues. The xylem is composed of vessels, tracheids, xylem fibres and xylem parenchyma. Phloem is composed of sieve tubes, companion cells, phloem fibres and phloem parenchyma.

Complex permanent tissues are also called vascular tissues because they help the transportation of water, minerals, and organic matter throughout the plant body. The two most common complex permanent tissues found in plants are Xylem and Phloem.
What is complex plant?
A plant that causes specific changes to soil biota may either positively or negatively affect the performance of the plant that subsequently grows in that location.
What is the function of lateral meristem?
Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness. Meristems form anew from other cells in injured tissues and are responsible for wound healing.
What are the complex tissue of plants write the components and functions of each of them?
Answer: Xylem and phloem are the conducting tissues of the vascular strands. Their main role is in the transportation of food, minerals, and water. Xylem is the tissue which is responsible for the transport of water in plants while the phloem is responsible for the transfer of food and nutrients in the plant.
What is complex tissue name the various kinds of complex tissues?
REVIEW SHEET
| Type of tissue Simple/complex | Cell types present | |
|---|---|---|
| Xylem | Complex tissue | Tracheary elements, parenchyma, Sclerenchyma (fibers) |
| Phloem | Complex tissue | Sieve elements, parenchyma, sclerenchyma (fibers) |
| Epidermis | Complex tissue | “ordinary” epidermal cells, guard cells, cells of trichomes |
What are complex tissues of great importance?
In respect of physiological and economic aspects, complex tissues are of great importance. Physiological importance: 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.
Which of the following is complex tissue in plants?
Phloem– It is a complex tissue that is made up of phloem parenchyma, companion cells, sieve tube cells and sieve plate. The function is to transport prepared food from the leaves to various parts of the plants. Therefore the correct answer is option ‘C’.
What is one of the most complex tissues?
NERVE TISSUE Nerve tissue is the most complex tissue in the body. It is the substance of the brain, spinal cord, and nerves.
What is complex tissue samacheer?
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. However, collenchymatous cells are not present in such tissues. Common examples are xylem and phloem.
What is complex tissue name the various kinds of complex tissue 9th samacheer?
Xylem and phloem are the two kinds of complex tissues. Xylem is a conducting tissue which conducts water, minerals and nutrients to upper parts of plants from root to leaves by giving mechanical support to the plant body. It is made up of xylem tracheids, xylem fibers, xylem vessels and xylem parenchyma.
What is parenchyma in biology class 9?
Consist of live unspecialized cells having thin cell wall. They are loosely packed and have large intercellular space (space between the cells). Provides support to the plant and present in all parts like roots, stems, leaves, fruits and seeds.
Why are complex permanent tissues called so?
Xylem and phloem are an example of complex permanent tissues. These tissues are named so because they are made up of more than one type of cells and all these different types of cells coordinate to perform the same function.
Is a complex permanent tissue answer?
Xylem is a complex permanent tissue.
What is complex tissue name complex tissue of plants discuss their importance to plant?
Complex Tissues. Tissues composed of more than one cell type are generically referred to as complex tissues. Xylem and phloem are the two most important complex tissues in a plant, as their primary functions include the transport of water, ions, and soluble food substances throughout the plant.
What is complex tissue and its types?
Complex tissue is composed of more than one kind of cells. They are two types, namely Xylem tissue and Phloem tissue. … They are two types, namely Xylem tissue and Phloem tissue. i. Xylem tissue: Xylem tissue consists of four types of cells, namely: Tracheids, Vessels or Trachaea, Xylem fibre and Xylem Parenchyma.
How are complex tissues different from simple tissues?
The primary difference between simple and complex tissue is, simple tissue is made up of only one type of cell whereas complex tissue is formed of many types of cells.
What is the function of xylem?
xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
What is the function of collenchyma?
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
What is the function of stomata?
Stomata (Fig. 1) are small pores on the surfaces of leaves and stems, bounded by a pair of guard cells, that control the exchange of gases—most importantly water vapour and CO2—between the interior of the leaf and the atmosphere.
Where complex tissues are found?
In vascular plants xylem and phloem are the complex tissues. Xylem helps in conduction of water and mineral ions from the roots to the other parts of plant body. Xylem and phloem together constitute conducting tissue or vascular tissues. In flowering plants they are found as vascular bundles.
What is the complex tissue made up of?
A complex tissue is made up of two or more than two types of cells which are aggregated from the beginning and perform a similar function. Complex tissues are conducting tissues, they are of two types phloem and xylem.
Which are the component of a complex tissue which among them is living in nature?
‘xylem parenchyma‘ is the component of a complex tissue, which is living in nature. Explanation: A groups of cells that have the same structure and function together to perform a specific task is called a tissue.
Which complex tissue is living in nature?
Note: Complex tissues are made up of more than one type of cell, which are either living or dead. Xylem is considered as dead tissue. Because among the four types of cells, only xylem parenchyma is living. On the other hand, phloem is considered as living tissue, because except phloem fibres, all are living in nature.
