Question

Mention the function of each meristematic tissue

Answer 1

Answer:

Functions of Meristematic Tissue:

1. Meristems are actively dividing tissues of the plant.

2. They are responsible for primary (elongation) and secondary (thickness) growth of the plant.

3. All new organs and their growth occur by the division of meristematic tissue.

4. Secondary tissues such as, wood, cork are also formed due to activity of meristematic tissue.

Types of meristematic tissue on the basis of function:

i. Protoderm

ii. Procambium

iii. Ground meristem

Protoderm:

Function:

Protection from mechanical injury

It gives rise to epidermis layer.

It is the outermost meristematic tissue

Procambium:

Function:

Transport of water and nutrition

It gives rise to vascular tissue (xylem and phloem)

It is the innermost meristematic tissue

Ground meristem:

Function:

It gives rise to cortex, endodermis, pericycle and pith in dicot and hypodermis, ground tissue in monocot.

Answer 2

•                                             MERISTAMATICTISSUES                                            .THIS TISSUES ARE A DIVIDING TISSUE.                                                                                         .IT GROWS UPON IN DIFFERENT CLIMATIC CONDITIONS.           .THIS TISSUE CONTAINS THREE TYPES OF TISSUES.                                                                                                                                                                         .THESE ARE (1)  APICAL MERISTEM      (2)   LATERAL MERISTEM     (3)   INTERCALARY MERISTEM.                              * APICAL MERISTEM IS FOUND IN THE STEM SO IT HELPS TO INCRESE THE STEM'S LENGTH.               *LATERAL MERISTEM IS FOUND IN THE SIDE OF THE STEM SO IT HELPS THE STEM TO INCREASE THE GIRTH.               *INTERCALARY MERISTEM IS FOUND IN THE NODES AND TWIGS OF THE STEM.IT MAINLY CONTROLS THE NODES OF THE STEM.
