• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is D Assertion is incorrect but Reason is correct

• Plant hormones are signal molecules.
• They are transported within the plant from one place to the site of action.
• Plant hormones control all aspects of growth and development, from embryogenesis, the regulation of organ size, pathogen defence, stress tolerance and through to reproductive development.
• They are present in the growing areas, such as in the stem, buds, and root tips.
• Hence, All plant hormones do not produce from the tip of the stem.
• The phytohormones are produced at one place and then transferred to other sites to produce desired effects.
• So, the correct answer is 'Assertion is incorrect. But Reason is correct'.
