Its true. Some plants need a female and male plant. The plants that dont are called self pollinating plants. Thats when things like the wind push "male pollen" into the middle of the flower where the "female pollen" is . I think kiwi trees/bush/vines are an example of male and female. (male and female are not the right word to use I think but its just easier to explain with
I wasn't addressing the male/female plant comment. That is without a doubt true.
The original poster said that plants feel pain, which is impossible without a nervous system to send pain impulses and a brain to interpret them.
