Plant Parts (Lateral Branch Root and Axillary Bud)

Lateral Branch Root and Axillary Bud

The lateral branch roots are shown near the soil of the plant. They are the roots besides the taproot that are part of the root system. The lateral branch roots extend horizontally into the soil and function in anchoring the plant into the ground. The branching of the lateral roots increases surface area which aids in water and nutrient absorption from the soil. (1)

The axillary bud is shown in the crevice between the stem and the petal. It is an embryonic shoot that will develop into a shoot. Axillary buds require plant hormones to grow and they will not grow unless the apical dominance is inhibited. (2)
