Difficulty Level:


Symplastic system

Find the wrong one.

  1. System of interconnected protoplasts
  2. Involves path through plasmodesmata
  3. Water has to enter the cells through the cell membrane
  4. Above a potential gradient movement

Difficulty Level:


Symplastic movement is slower than apoplastic movement

  1. Because it involves cytoplasmic streaming always
  2. Molecule has to enter through the cell membrane
  3. Because it is down the gradient
