Plants have no blood, yet we sometimes say that a plant is “bleeding”. How do you justify this?
Bleeding happens only due to injury.
Bleeding is when sap leaks from a wound or pruning cut on a tree, shrub, or woody climber. Sometimes this may be a gentle seeping, other times a copious flow. The plant sap escapes from the ruptured or cut surface of a plant.
The root pressure generated by a plant assists in bleeding.
