Phytomer

Phytomer

Phytomers are functional units of a plant continually produced by root and shoot meristems throughout a plant's vegetative life-cycle. A typical phytomer consists of a node to which a leaf is attached, a subtending internode, and an axillary bud at the base of the leaf.

Initially, a young plant will only produce phytomers at its apical meristems but later in development, secondary meristems will begin to form and phytomers will be formed on this lateral plant growth.
