They were twice repelled, but the third time they stormed the palisades.
Below the upper epidermis is the palisade mesophyll, which is the most important photosynthetic tissue of the plant.
Thus, the seed does not imbibe water or germinate until the integrity of the endocarp, which contains an outer layer of palisade cells, is disrupted.
The palisade parenchyma and thick cuticle thus appear to form the two main structural barriers to desiccation.
The number of palisade mesophyll cell layers was 2-3 in shade plants, while for sun plants it was 3-4.
We reduced variability by eliminating from the study cells of the two protoderm layers, the provascular regions and the palisade ground meristem.
After shedding, the parenchymal cells become lignified and die, but the structure of both cuticle and palisade cells is retained.
Hatching occurs within 7-12 days through the egg side in contact with the leaf surface, and neonates initiate the feeding on the palisade parenchyma.
