AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The plant's bending is caused by hormonal (chemical) coordination — auxin causes unequal growth, which is slow. The cat's leap is driven by the nervous system transmitting rapid electrical impulses via specialised nerve and muscle tissue.
Plants lack nervous tissue and muscle tissue entirely. Without these, they cannot generate or conduct fast electrical impulses, so they cannot produce the rapid, forceful responses that animals can.
Examiners look for two key contrasts: (1) plant = chemical/hormonal, slow, growth-based vs. animal = nervous/electrical, fast, muscle-based; and (2) the reason plants cannot use the animal mechanism — absence of nervous tissue and muscles. Keep these points distinct and precise. Don't write a full paragraph on hormones — this is only 2 marks.
