Most growth occurs at the terminal bud. The presence of a terminal bud is partially responsible for the inhibition of growth of the axillary buds. This is known as apical dominance. But the removal of the terminal bud can sometimes enhance the growth of axillary buds and thus make a plant more bushy. Leaves Are the primary photosynthetic organs of a plant.
Leaves consist of two parts - the blade and the petiole .
The veins of a leaf are the vascular bundles, collections of xylem and phloem Plant Growth Primary Growth versus Secondary Growth - Primary growth is growth in the length of a plant whereas secondary growth refer to an growth resulting in an increase in diameter.

Secondary phloem is the secondary growth tissue that conducts food that the plant makes from the leaves to the rest of the plant. The cork cambium is involved in producing the tough, thick covering of a stem and root. To see secondary xylem and secondary phloem, click here .
