A cell is the basic structural and functional unit of life.

A cell is the basic structural and functional unit of life. A group of cells that are similar in structure and perform the same function is called a TISSUE. Like animals, the plant is also made up of different kinds of tissues. These tissues are mainly classified into two types based on the cell’s ability to split or not. They are Meristematic tissues and Permanent tissues.

A group of cells that are in a state of division are known as Meristematic tissues. The properties of Meristematic tissues are: 1.Undifferentiated 2.Capable of cell division 3.Helps in the growth of plants.

A group of cells that do not bifurcate further and are distinguished based on the functions the tissues perform. The Properties of Permanent Tissues are:

The figure given below, depicts the types of plant tissues.

Based on the location, Meristematic tissues can be classified as:

Meristematic cells that split up, extend, become differentiated, and perform particular functions are called permanent tissues. There are two types of permanent tissues; simple and complex: Simple Tissue: Dermal and ground tissues.

Note: The CUTICLE-Epidermis covering is made of a waxy substance called cutin.

The main function of ground tissues is to provide support, strength, and flexibility to plants. The Three Types of Ground Tissues are:

Vascular Tissues: Xylem and Phloem. These tissues are also known as conducting tissues because of their important role in water and food transportation. (image will be uploaded soon)

Term coined and discovered by Nageli (1858)

Composed of four different types of cells called; tracheid, trachea, xylem parenchyma and xylem sclerenchyma.

Composed of four different types of cells called; sieve tubes, companion cells, Phloem parenchyma and phloem fibers.

Except Xylem parenchyma, all other cells are dead.

Except phloem fiber, all phloem cells are living.

They are made up of only one type of cells

They are made up of more than one type of cells

Helps in storage of food and mechanical support.

Helps in transportation of water, sugars, minerals, and other metabolites.

Eg: Parenchyma, Collenchyma, Sclerenchyma
