Plant tissues are mainly divided into meristematic tissue and permanent tissues. Meristematic cells are those which are capable of active division and are further classified as apical,intercalary and lateral meristem. Second are the permanent tissues which cannot divide and are classified as simple permanent and complex permanent tissues. Simple permanent are classified as parenchyma,collenchyma and screlenchyma. Complex are divided into xylem and phloem which are known as vascular bundles of plants.
Characteristics:-
• It is the basic packaging tissue that fills the spaces between other tissues and is found most abundantly in plants.
• They have undifferentiated cells with thin cell walls made of cellulose.
• They have large intercellular spaces as the cells are loosely packed.
Answer:
A collection of cells performing a specific function is called tissue. Plant tissues can be grouped into plant tissue systems each performing specialized functions. 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.
Types of Plant Tissues
Plant tissues can be broadly classified based on the ability of the cells to divide into Merismatic tissue and Permanent tissue.
Merismatic tissues consist of a group of cells that have the ability to divide. These tissues are small, cuboidal, densely packed cells which keep dividing to form new cells. These tissues are capable of stretching, enlarging and differentiating into other types of tissues as they mature. Meristematic tissues give rise to permanent tissues. Merismatic tissues can be of three types depending on the region where they are present: Apical meristems, lateral meristems, and intercalary meristems.
Permanent tissues are derived from the merismatic tissues and have lost their ability to divide. They have attained their mature form. They are further classified into two types: Simple and complex permanent tissues.
