Question

The apical bud of a shoot produces ________, resulting in the inhibition of lateral bud growth.

Answer 1

Auxin, which is produced by the apical bud, encourages the growth of apical buds while inhibiting the growth of lateral buds that are located lower on the stem, toward the axillary bud.

What does a shoot's apical bud produce?

Auxin, a hormone produced by the apical bud, travels via the plant's circulatory system (phloem) down the stem and prevents axillary buds from expanding, which would otherwise result in the production of additional side shoots from the plant cells.

What function does auxin serve?

Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance,and the transition to blooming..

What are the four roles that auxins play?

• Its primary uses are to stimulate shoot growth in culture and to enhance lateral and accidental shoot growth.
• aids in overcoming auxin-induced apical dominance.
• encourage the development of leaves' chloroplasts.
• encourages the mobilization of nutrients and delays leaf senescence.
