Question

Plants respond to various stimuli by

• A. Shedding leaves
• B. Growing
• C. Speeding up fruit ripening
• D. Peeling of bark

Answer 1

The correct option is B Growing

Plants produce hormones in response to external stimuli. They exhibit this by tropism in which they grow towards sources of water and light. In positive tropism, plants grow in the direction of stimulus and in negative tropism plants grow in the direction opposite to stimulus. Thus the correct answer is option B.
