How is meristematic tissue different from permanent tissues ?
Difference between Meristematic and permanent
Meristematic tissue :
- Meristematic tissue is present at the tip of the root and stem and in between the xylem and phloem. Form apical meristematic tissue when present at the tips. It is in the form of cambium in between the xylem and phloem.
- Meristematic cells divide and form other types of tissues. The cells are thin walled.
- Meristematic cells may be intercalary as in case of monocots.
- The cells are small and isodiametric, vacuoles are small or absent.
- Respiratory and biosynthetic activities maximum.
- The cells are immature and mitochondria simple.
- Proplastids act as plastids.
- Permanent tissue may be simple as parenchyma, collenchyma or sclerenchyma and it may be complex as xylem and phloem.
- These are made up of more than one kind of cells. These perform a common function Xylem and phloem form vascular system of the plant. These cells do not have the power to divide.
- These cells may act as epidermis cortex or grit cells. Sclerenchyma gives strength.
- Living cells of permanent tissue have vacuoles. The cells are large and of different shapes.
- Both these activities are low.
- The cells fully mature, mitochondria fully developed.
- Living cells have plastids.
