Why parenchyma cell is a type of permanent tissue? Parenchyma cell possess the power of division then why we called it as permanent tissue. please explain me I will definitely mark it as the brainlist answer.
SatishMallick016:
I have searched it on Google . it sometime shows that parenchyma cell can divide and sometimes shows that parenchyma cells cannot divide.What is correct please answer me¿¿¿??? I am totally confused!!¡!¡!¡

hey mate
parenchyma a type of permanant tissue . it consists of relatively unspecialised cells with thin cell walls . they are live cells . they are loosely packed, so that large spaces between cells are found in this tissue. the tissue provides support to plants and stores food .
in some times it contains chlorophyll and performs photosynthesis and then it is called chlorenchyma . in aquatic plants large air cavities are present in parenchyma to give buoyancy to the plants to help them float . such parenchyma type is called arenchyma

ok !I know this that it is totally copied from NCERT book. I have read NCERT and reference book carefully so I know that the sentences are from NCERT book. if you search it on Google then it sometimes shows that it has the ability to divide and sometimes shows that it has not the ability to divide.
what is correct. just answer my question not give me a theory
you asked i answered
no.matter from where i got it
ok it's right !so in your theory you have write that parenchyma cell is unspecialized and is a type of permanent tissue but the definition of permanent tissues is that the cells of permanent tissue cannot divide or in other words we can say that they are specialised then how can you say that parenchyma cell is a permanent tissue.
so wat
take the ans or leave it
I want the reason that why parenchyma cell is called as permanent tissue .

Explanation:
Yes , parenchyama is surely a permanent tissue , differentiated and do not posses further dividing capacity.
But at some places , it undergoes process of dedifferentiation by which it is no more differentiated and can divide again . Some of these locations are cork cambium , interfascicular cambium .
Otherwise as you think , parenchyma cells being permanent should not divide . But following dedifferentiation , they are found to divide.
You can read more about de differentiation if u want to study in detail or ask your teacher about it.
