Raphide - an overview | ScienceDirect Topics

IO crystals (raphides) resembling dual-pointed needles are arranged and packed in bundles and located within specialized cells (idioblasts) found throughout the plant. 4 Damage to the tip of the idioblast, such as during chewing, allows water to enter the cell, causing swelling of a gelatinous material surrounding the raphides.This stimulates the forceful propulsion of the raphides from the ...

Calcium oxalate crystal morphology: Trends in Plant Science

Plants invest considerable resources of carbon and calcium in crystal formation, indicating that it is an important basic process in growth and development. The diversity of crystal shapes, as well as their prevalence and spatial distribution, have led to several hypotheses regarding crystal function in plants. The proposed functions include roles in ion balance, in plant defense, in tissue ...
