MCQ
Plant tissues can be separated into single cells by using :
  • ✓
    Cellulase and pectinase
  • B
    Cellulase and auxins
  • C
    Cellulase and peg
  • D
    Auxins and cytokinins
✓

Answer

Correct option: A.
Cellulase and pectinase
Plant cells are surrounded with a cellulosic cell wall.
Between adjacent plant cells is present middle lamella.
The middle lamella is made up of calcium and pectin.
Hence, plant cells of a tissue are separated from each other with the help of cellulase and pectinase enzymes.
These enzymes are commercially used in clearing of fruit juices to dissolve plant fibres.
