Question

E. Differentiate between
1. meristematic and permanent tissues.
3. parenchyma and sclerenchyma.
5. xylem and p phloem​

Answer 1

parenchyma:The cell walls are uniformly thicked.parenchyma does not have any permanent mechanical function except when it's cells are turgid.parenchyma is formed both in the outer and inner parts of plant organs.

sclerenchyma:it is generally formed of dead cells.lumen is narrow .the wall is uniformly thicked.The thickening can be cellulose,lignin or both

xylem:the conducting cells are vessels.xylem conducts water nd minerals xylem lies deeper in plant organs.

phloem:The conducting cells are phloem sieve tubes.phloem translocates organic food.phloem is situated towards outer side.

Maristematic:These tissues do not have large vacuoles.they are thin walled and isodiametric.

permanent:these have often large central vacuoles .they may be thin or thick walled
