Why are plant responses not like the fast nervous responses of animals?
Answer and explanation
Correct answer: Plants do not have a nervous system and muscles
Animals can produce rapid movements because their nervous systems transmit electrical signals and their muscles act as fast effectors. Plants lack neurons and muscles, so they cannot use the same pathway. They still coordinate responses through chemical signals and changes in growth or water balance, such as bending toward light or altering leaf movement. Hence option A is correct; the other statements incorrectly deny plant chemicals, growth or light detection.
