If you were to say humans and animals should not be used for experiments and plants is the best choice, I would strongly disagree with you on that. Although plants do not show any emotions or feelings, that doesn't mean it's cruel to test on plants. But the most important thing is if we are testing some new medicines on plants, they won't be able to physically react even though we might know how is it chemically reacting with the help of a microscope. It's not like if we test new medicines on animals and if something went wrong, we will know. Animals show their emotions and feelings and so, if something goes wrong, they will physically react such as scream or behave weirdly. Animals are more worth it than plants or humans.









). If one is to classify the worth of a living organism by how big they are, it suggests that size and sapience have an obvious correlation. Since there are plenty of non-sapient animals far larger than humans this can clearly be disproved, yet this idea of small lifeforms like bacteria (and in the minds of many, up to the size of bugs or even rodents) being of less worth is as I say, only due to how we personify larger animals. Plants eat, reproduce, excrete, and all sorts of other things that all animals do, but they don't have any similar features to us so we don't see them as being able to share in our emotions etc. - something we only see cats and dogs and the such like being able to do because they have some responses that look like our own
