Vascular plants have up to three types of supporting tissue:
- The collenchyma, a tissue of living cells,
- the sclerenchyma, a tissue of nearly always dead cells, and
- the vascular tissue consisting of both living and dead cells. It is responsible for the transport and dispersal of water, nutriments and assimilates.

What are conducting tissues?
noun. tissue of higher plants consisting mainly of xylem and phloem and occurring as a continuous system throughout the plant: it conducts water, mineral salts, and synthesized food substances and provides mechanical support. Also called: conducting tissue.
What is supportive tissue?
A supportive tissue is a type of connective tissue in which the matrix is hard and rigid due to the presence of inorganic salts. The matrix encloses few cells. Adding on, fibres may be present or absent. It is also known as skeletal tissue since it forms the internal supporting framework of the body.Sep 14, 2020
What are the different types of plant tissues?
Different types of plant tissues include permanent and meristematic tissues.
What are meristematic tissues?
Growth in length and growth in diameter of the plant is carried about by these cells. The Meristematic cells are cubical, living cells with a big nucleus. These cells are meticulously crammed with no intercellular spaces. Depending on the section where the meristematic tissues are existing, they are categorized as intercalary, lateral and apical meristems.
What are the two types of permanent tissues?
Complex Permanent Tissue: These tissues include phloem and xylem. Xylem is valuable for the transportation of water and solvable constituents. It is made up of xylem parenchyma, fibres, vessels and tracheids.
What is the function of the stomata?
The stomata perforates the epidermis at certain places. The stomata help in loss of water and gaseous exchange. Cork – This is the external protective tissue, which substitutes the epidermal cells in mature stems and roots. Cork cells are lifeless and lack intercellular gaps.
Where is the intercalary meristem located?
Lateral meristem upsurges the thickness of the plant. Intercalary meristem is found at the internodes or at the base of the leaves. Intercalary meristem upsurges the size of the internode. Old meristematic cells lose the capability to distribute and convert into permanent tissues.
What is the apical meristem?
Apical meristem is existent at the growing tips or apical of stems and roots. Apical meristem upsurges the length of the plant.
What is a phloem made of?
It is made up of xylem parenchyma, fibres, vessels and tracheids. Phloem is valuable in the transportation of food particles. Phloem consists of phloem parenchyma, phloem fibres, companion cells, sieve cells and sieve tubes.
What are the tissues that make up plants?
Parenchyma – These tissues are found in the soft parts of a plant such as the roots, stems, leaves, and flowers. The cells of this tissue are loosely packed and contain large intercellular spaces between them. Each cell has a vacuole at the center. The functions of parenchyma tissues are storage, photosynthesis, and to help the plant float on water.
What are the functions of plant tissues?
Functions of plant tissues 1 Help provide mechanical strength to organs. 2 They help in providing the elasticity and flexibility to the organs. 3 They help the tissues to bend easily in various parts of a plant like- leaf, stem, and branches without damaging the plant 4 The xylem and phloem tissues help in transportation of material throughout the plants 5 They divide to produce new cells and help in the growth of the plants. 6 They help in various cellular metabolisms like photosynthesis, regeneration, respiration, etc.
What is a complex permanent tissue?
Complex Permanent Tissue. Unlike simple permanent cells which look the same and are made up of one type of cells, complex permanent tissues are made up of more than one type of cells. These different types of cells coordinate to perform a function. Xylem and Phloem are complex permanent tissues and are found in the vascular bundles in the plants.
Where are xylem and phloem found?
Xylem and Phloem are complex permanent tissues and are found in the vascular bundles in the plants. Xylem- It consists of tracheids, vessels, xylem parenchyma and xylem fibres. Tracheids and vessels are hollow tube-like structures that help in conducting water and minerals. The xylem conducts only in one direction i.e vertically.
What is the function of phloem?
Unlike the xylem, phloem conducts in both directions. It is responsible for transporting food from the leaves to the other parts of the plant. Phloem contains living tissues except for fibres that are dead tissues.
What is the role of xylem and phloem in the vascular strand
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 plant tissue system?
A plant tissue system is defined as a functional unit, connecting all organs of a plant. Plant tissue system is also grouped into various tissues based on their functions. Let’s find out more.
What is the role of xylem tissue in plants?
Xylem tissue is the responsible tissue for conducting mineral salts and water throughout the plant. Tissue contains 4 cell types namely vessel elements, tracheids, xylem parenchyma and xylem sclerenchyma.
What is the cell theory of plants?
According to the Cell theory all living beings are created from cells. That means we can further investigate the structure and functions of plants. Bunch of cells showing similarities and in origin, growth and designed to work on very special tasks are known as tissues. So, here you’re going to learn about plant tissues and their structures ...
What is the cell wall of parenchyma?
Parenchyma tissue cells are living cells which are spherical or elongated in their shapes. As you know plant cells have cell walls even animal cells don’t have it. So the cell wall of this tissue is made with pectin, cellulose and hemicellulose.
What is the shape of a collenchyma?
Collenchyma Tissues. Collenchyma tissues have a polygonal shape of living cells with corners thicken with cellulose and pectin. So these cells are adapted to provide extra structural support and mechanical energy to the plant.
What are the 5 types of phloem tissue?
Phloem Tissue. Sieve tubes, parenchyma, sclereidons, fibers and companion cells are the 5 types of Phloem tissue. Translocation of food solutions throughout the plant is done by the sieve tubes which are long and have a tube like structure. They are formed by end to end fusion of sieve tube elements.
What is the function of parenchyma cells?
Parenchyma cells act as a packing tissue in the outer cortex and the central pith of young stem and roots. These cells have an important property of osmotic property. They provide support and becomes tightly packed when turgid happens. You can see these tissues in potato stem tuber as food storage tissues.
What is the structure of a tracheid?
Tracheids are lignified and elongated which have single cells. Structure known as simple pits are available in low thicken areas just like schlerenchyma tissues. Water is passing through tracheids and simple pits regularly. The tracheid walls are lignified as spiral or annular.
