Biology / Unit 11 Bio 2505 short lesson, about 20 seconds
Three Meristem Locations: Apical, Lateral, Intercalary
Captions available
The idea
Apical meristems at stem and root tips extend a plant's length; lateral meristems thicken it; intercalary meristems, found only in monocots, elongate leaf bases.
In practice
Intercalary meristem at the blade's base lets a mowed grass leaf regrow from below even after its tip is cut off.
Where people slip
Only monocots carry intercalary meristem — a mowed dicot leaf cannot regrow the same way.
