The present paper consists of two parts. In the first, some issues related to the character of biological experiments conducted under in vitro cultures are portrayed. The relevant aspects of these procedures are explicated from the viewpoint of the experimental botanist. It is a case study for the considerations in the second part, which presents selected philosophical and legal issu-es involved in biological experiments from the general perspective of philoso-phical investigations concerning the problem of plants’ axiology. Obviously, the nature of the considerations is limited; not all important questions from the perspective of biology and philosophy have been raised. Nevertheless, the authors hope that the analyzed issues may be interesting for both biologists and philosophers.
