There are plenty of animals that don't nurse their young. That's a peculiarity of mammals.

And the scientific evidence suggests that plants do likely feel something akin to what could be called pain.

Their inability to scream with sounds detectable by human ears isn't evidence they don't feel anything.

It's not absurd. It's what science tells us -- that plants emit chemicals to communicate to other plants about infestations of insects so they can take action to protect themselves and when injured they may give off a "pulse", aka a type of scream.
