Answer 1

Plants may lack brains, but they have a nervous system - yes

Explanation:

Plants may lack brains, but they have a nervous system, of sorts. And now, plant biologists have discovered that when a leaf gets eaten, it warns other leaves by using some of the same signals as animals.

Answer 2

Answer:

No, plants lack a nervous system.

Explanation:

• Plants lack a nervous system like animals but they do respond to and coordinate their behavior to environmental changes with the help of various chemicals called phytohormones released by the stimulated plant cells.

• These hormones help them to coordinate growth responses. Auxin, gibberellins, abscisic acid, jasmonic acid, cytokinins are a few plant hormones.

For example,

• Plants like the pea plant climb up other plants with the help of tendrils that are sensitive to touch. When they come in contact with any support, the part in close contact with the object fails to grow as rapidly as the part of the tendril away from it, which is why the tendrils circle the object in contact and remain cling to it.

So plant responds through hormones.
