Question 3 (11.111111111 points)

Listen
Research station staff study how plants respond to environmental stresses like drought, temperature extremes, and nutrient limitations through changes in growth patterns and physiology. What do these responses demonstrate about plant biology?
Question 3 options:

Plants actively sense and respond to environmental conditions through various physiological and developmental mechanisms

Plants are passive organisms that cannot respond to environmental changes or adjust their physiology

Only animals can respond to environmental changes; plants lack any response or sensing systems

Plant responses to environment are always identical regardless of the type or severity of stress

Answer 1

Plants actively sense and respond to environmental conditions through various physiological and developmental mechanisms

Explanation: Plants detect stresses (drought, temperature, nutrient levels) and adjust growth, hormone signaling, stomatal behavior, root/shoot allocation, gene expression, etc., to cope — they are not passive and responses vary with stress type and severity.
