Question

Give the chief characteristics of meristematic tissue

Answer 1

⭐Meristemetic tissue :

Growth in plants is largely restricted to specialised region of active cell division.

⭐Types of Meristemetic :

1) apical meristem.
2) intercalary meristem.
3)primary meristem.
4) secondary meristem.

⚫Apical meristem :
~~~~~~~~~~~~~~

Which occur at the tips of roots and shoots and produce primary tissues.

Root apical meristem :
>>>>>>>>>>>>>>>>>>>

Occupies the tip of a root.

Shoot apical meristem :
>>>>>>>>>>>>>>>>>>>
Occupies the distant most region of the stem axis.

⚫Intercalary meristem :
~~~~~~~~~~~~~~~~~~
Which occur between mature tissue.

Occur in grasses, regenerate parts removed by grazing herbivores.

⚫Primary meristem :
~~~~~~~~~~~~~~~~
Both apical and intercalary meristems are primary meristem.

⚫Secondary meristem :
~~~~~~~~~~~~~~~~~~
The meristem that occurs in the mature regions of roots and shoots of many plants, particularly those that produce woody axis and appear appear later than primary meristem.

Following are responsible for producing secondary meristem :
¬Fascicilar vascular cambium
¬interfasicular cambium.
¬cork cambium.

Hope it's help you friend ☺️☺️☺️

Answer 2

Answer:

$\star \mathbf{Defination}$

Meristematic tissue is made up of group of cells that divide repeatedly to form new cells

$\star \mathbf{Characteristics}$

• They have thin cell walls
• They are tightly packed with no intercellular spaces
• It has either small vacuoles or no vacuoles

$\star \mathbf{Types}$

• Apical Meristem
• Intercalary Meristem
• Lateral Meristem
