Hormones act as signal molecules between all body systems. B. Increased heart rate and blood flow decrease oxygen supply. C. Exercise is important for the body to function properly. D.

The apical bud of a shoot produces ________, resulting in the inhibition of lateral bud growth.
In-s [12.5K]

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.

<h3>What does a shoot's apical bud produce?</h3>

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.

<h3>What function does auxin serve?</h3>

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..

<h3>What are the four roles that auxins play?</h3>
  • 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.

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.
