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 is an example of meristematic tissue?
Some of the primary meristematic cells may produce cells that become permanent tissues, e.g. dermal, ground, and primary vascular tissues. … 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.
What are the 3 types of meristems?
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 type of tissue is 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 is meristematic tissue class 8?
Meristematic tissues
contain living cells with varied shapes
. … The cells have no intercellular space. The zone where these cells exist is known as meristem. The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc.
What is simple permanent tissue?
Simple permanent tissues are
a group of cells which are similar in origin, structure and function
. … Its main function is to provide mechanical support, elasticity, and tensile strength to the plants. c) Sclerenchyma- are tissues consists of thick-walled and dead cells.
What is simple permanent tissue class 9?
Simple permanent tissues are
composed of cells which are structurally and functionally similar
. These tissues are made up of one type of cells. A few layers of cells beneath the epidermis are generally simple permanent tissue.
What is the main characteristics of permanent tissue?
Characteristic features of permanent tissues: (i)
Cells may be living or dead.
(ii) Cell walls may be thin or thick. (iii) Cells may contain reserve, excretory or secretory substances.
Why are meristems virus free?
The reasons for the meristem to be free from the virus:
Meristem has continuously and rapidly dividing cells
. These cells have a high rate of metabolism and viruses cannot replicate in such cells. Most of the viruses migrate through Vascular elements but at the tip/meristem region, vascular elements are not formed.
What happens if meristematic tissue is absent in plant?
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.
What is the function of permanent tissue?
Functions of Permanent Tissues
The permanent tissues
store the food materials such as starch, proteins, fats and oils
. They show essential metabolic functions like respiration, photosynthesis, secretion, etc. Chlorenchyma helps in photosynthesis, and aerenchyma helps in buoyancy and gaseous exchange.
How many types of permanent tissue are there?
Cells of meristematic tissue differentiate to form different types of permanent tissues. There are
2 types
of permanent tissues: simple permanent tissues. complex permanent tissues.
Where meristematic tissue is found?
Meristematic tissues are found in many locations, including near the
tips of roots and stems
(apical meristems), in the buds and nodes of stems, in the cambium between the xylem and phloem in dicotyledonous trees and shrubs, under the epidermis of dicotyledonous trees and shrubs (cork cambium), and in the pericycle of …
What are the three types of meristematic tissue class 9?
- Apical meristem is present on root and shoot tips of the plant. …
- Intercalary meristem is present on leaf base and nodes.
- Lateral meristem is responsible for increase in circumference i.e. girth of the stem or root of the plant.
How many tissues are in our body?
There are
4 basic types
of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is meristematic tissue explain with diagram?
Answer: Meristematic tissues, or simply meristems, are
tissues in which the cells remain forever young and divide actively throughout the life of the plant
. When a meristematic cell divides in two, the new cell that remains in the meristem is called an initial, the other the derivative.
