Answer 2

Both are true and R is the correct explanation of A.

• Plants lack nociceptors, the particular receptor types that are hardwired to respond to pain, in contrast to humans and other animals.
• There is no nervous system and as they lack a neural system, plants respond to stimuli more slowly than mammals do.
• They naturally lack the brains essential to convert such sensations into genuine experiences since they also lack brains. Because of this, plants are unable to experience pain.
• However, a plant may be regulated and coordinated with the help of a number of plant hormones. Phytohormones are what these are called. Plant hormones include:

1. Auxin
2. Cytokinin
3. Gibberellins
4. Abscisic Acid

Thus, Both are true and R is the correct explanation of A.
