how are meristematic tissue different from permanent tissues ? write their function also.
Answers
Answer:
Difference between Meristematic and permanent Meristematic tissue:
Meristematic tissue:
1) Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches.The cells present in these tissues constantly divide to produce new cells.
2) The cells actively divide to produce new cells.
3) Meristematic cells may be intercalary as in case of monocots.
4) The cells are immature and mitochondria simple.
5) The cells have large nuclei and vacuoles are absent.
Permanent Tissue:
1) The cells produced by meristematic tissues grow and,on maturity,get differentiated to carry out specialised functions.These cells form permanent tissues as they do not divide further.
2) Based on the type of function they perform,permanent tissues are of three types-protective tissue ,supporting tissue and conducting tissue.
3) Living cells of permanent tissue have vacuoles.The cells are large and of different shapes.
4) The cells fully mature,mitochondria fully developed.
5) These cells may act as epidermis cortex or grit cells. Sclerenchyma gives strength.
Explanation:
All functions of both the tissues with differentiation!
Explanation:
A cluster of cells, performing similar functions are known as tissues. In plants, tissues are classified broadly into two groups on the basis of cell division capacity, namely – Meristematic and Permanent Tissue. Meristematic tissues in plants consist of a mass of undifferentiated cells whose main function is to participate in plant growth.
Permanent tissues, on the other hand, are differentiated tissues, carrying out dedicated functions. Some of which is to conduct, render mechanical strength to the plant or even to carry out photosynthesis. These tissues are originated, differentiated and derived from meristematic tissues.
