/MAIR-ih-stem/🔬 Anatomy●●● Advanced
Also known as: growing point
Tissue composed of actively dividing, undifferentiated cells that are the source of all new plant growth. Apical meristems at shoot and root tips drive elongation; lateral meristems (cambium) drive thickening.
Etymology
From Greek meristos, meaning "divisible," from merizein (to divide).
Example
“Plant hormones produced in the apical meristem control the growth and branching pattern.”
