What is meristematic tissue and its function?
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.
What meristem develops into the three tissue systems?
There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
What is meristematic tissue Short answer?
“Meristematic tissue is the plant tissue that has the ability to divide actively throughout its life.”
Can a plant live without meristem?
The short answer is no – the meristem are the areas in plants that produce new cells for roots, tips of shoots and branches, leaves, flowers, and the vascular cambium that increase the diameter of tree parts. So without meristem, there is no growth.
What cells make up meristematic tissue?
The meristem is a type of tissue found in plants. It consists of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants.
What happens to the cells formed by meristematic tissue?
The cells formed by meristematic tissue take up a specific role and lose their ability to divide. As a result, they form a permanent tissue. This process of taking up a permanent shape, size and function is called differentiation.
What is meristem give an example?
A primary meristem is a type of meristematic tissue that is responsible for the primary growth. An example of a primary meristem is the apical meristem. Apical meristems are meristematic tissues located in the apices of plant, e.g. root apex and shoot apex. See also: meristem.
What happens if meristematic tissue is absent in plants?
Answer: If meristematic tissues are not present, the growth of the plants would be stop. Because meristematic tissues consist of dividing cells and are present at growing points of plants. These are responsible for the growth of plants.
Why is meristematic tissue so important to a plant?
Plants grow larger via cell division and cell elongation. Simple plant growth is facilitated by meristem tissue because it is the primary site of cell division (mitosis) in the plant. Because the source of all new cells in a plant is the meristem, this tissue plays an important role in organ development as well.
Is meristem a stem cell?
Meristem cells are a group of cells that reside at the shoot and root tips of plants. As undifferentiated (or slightly differentiated cells) they are considered as stem cells given that they are the origin of many of the cells that go on to rapidly differentiate/specialize and form various parts of the plant.
How does a meristematic tissue become a permanent tissue?
These meristematic cells lose the ability to divide and take up a specific role. The permanent tissues are formed by the differentiated cells, which become specialised to perform specific functions like protection, support, storage and conduction.
What is difference between meristematic tissue and permanent tissue?
Meristematic tissue has cells small in size and isodiametric in shape. Permanent tissue has cells large in size and their shape varies. Vacuoles are usually absent in meristematic tissue. Vacuoles are present in living cells of permanent tissue.
What are the three types of meristematic tissue?
There are three types of meristematic tissues: apical (at the tips), intercalary (in the middle) and lateral (at the sides). At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone.
What do you mean by meristematic tissue?
Meristematic Tissue Meristematic Tissue Definition. “Meristematic tissue is the plant tissue that has the ability to divide actively throughout its life.” Characteristics of Meristematic Tissue. The cells of these tissues are commonly called meristems. Types of Meristematic Tissue. The earliest and youngest meristematic tissue.
What kinds of tissue can a meristem cell become?
Numerous cells in various stages of mitosis can be observed. Apical meristems differentiate into the three basic types of meristem tissue which correspond to the three types of tissue: protoderm produces new epidermis, ground meristem produces ground tissue, and procambium produces new xylem and phloem.
What is the important characteristic of meristematic tissue?
Cells have the power of active division.
