What is meristematic tissue and its types?
What is meristematic tissue and its types?
Meristematic cells are generally small and cuboidal with large nuclei, small vacuoles, and thin walls. A plant has four kinds of meristems: the apical meristem and three kinds of lateral—vascular cambium, cork cambium, and intercalary meristem.
Where are lateral meristems located?
stem
Lateral Meristems – The lateral meristems are present on the lateral side of the stem and root of a plant. These meristems help in increasing the thickness of the plants. The vascular cambium and the cork cambium are good examples of a lateral meristematic tissue.
Where is intercalary meristem located?
Intercalary meristem is a type of meristematic tissue, such as that found at the base of nodes and leaf blades of monocots. Intercalary meristem is a type of meristematic tissue associated with the growth in length in the middle position, thus the name.
Where are meristems located in plants?
Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses).
Where are apical meristems located?
tips of shoots
Apical meristems, which are located at the tips of shoots and roots in all vascular plants, give rise to three types of primary meristems, which in turn produce the mature primary tissues of the plant.
Where are meristems located?
What is the location of lateral meristem?
Lateral Meristems – The lateral meristems are present on the lateral side of the stem and root of a plant. These meristems help in increasing the thickness of the plants. The vascular cambium and the cork cambium are good examples of a lateral meristematic tissue.
Where is the grass meristem?
The growing points at the base of the leaf blade and the base of the sheath, collectively, are called the intercalary meristem. At the very tip of a tiller is the terminal growing point or apical meristem. The apical meristem is the growing point that produces the seedhead of a grass plant.
What is meristematic tissue in plants?
Meristematic tissues are cells or group of cells that have the ability to divide. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells. The two types of meristems are primary meristems and secondary meristems.
Where is meristem located and what’s its job?
Meristems are regions of unspecialised cells in plants that are capable of cell division. Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.
How do the locations and the functions of the three types of meristematic tissues compare?
How do the locations and the functions of the three types of meristematic tissues compare? Apical meristems found at nodes and bases of leaf blades promote growth by elongation; lateral meristems found in the vascular and cork cambia promote increase in girth and intercalary.
What are the characteristic features of meristems?
The cells of these tissues are commonly called meristems.
What are the functions of meristems?
Meristems are usually found in the growing region of plant organs such as shoot apex and root apex. Usually meristem originates from the embryonic cells. The primary function of meristem is to assist in plant growth and development. Meristematic cells are characteristically different from other differentiated cells in terms of many aspects.
What is a meristematic cell?
The meristematic cells can be called the first cells of the plant which are mainly found at the tips and lateral sides of plants. They can be broadly classified into primary and secondary meristems depending on the type of growth carried out by these tissues.
What are the functions of tissue?
Functions of Meristematic Tissue. It is responsible for the growth of the new organs. Involved in the movement of water and nutrition within the plants. These tissues are responsible for both primary and secondary growth of the plant. It is the outermost tissue, functions by providing protection from mechanical injury.
