This paper examines the biosemiotic approach to the study of life processes by fashioning a series of questions that any worthwhile semiotic study of life should ask. These questions can be understood simultaneously as: (1) questions that distinguish a semiotic biology from a non-semiotic (i.e., reductionist–physicalist) one; (2) questions that any student in biosemiotics should ask when doing a case study; and (3) still currently unanswered questions of biosemiotics. In addition, some examples of previously undertaken biosemiotic case studies are examined so as to suggest a broad picture of how such a biosemiotic approach to biology might be done

This article analyses the possibility to look at living systems as biorhetorical systems. Rhetorics of biology, which studies the rhetoric of biological discourse, is distinguishable from biorhetorics, which attempts to analyse the expressive behaviour of organisms in terms of primordial (unconscious) rhetoric. The appearance of such a view is a logical consequence from recent developments in new (or general) rhetorics on the one hand (e.g., G. A. Kennedy's claim that rhetoric exists among social animals), and from the biosemiotic approach to living systems on the other hand.

Asking, whether plants have semiosis, the article gives a review of the works on phytosemiotics, referring to the tradition in botany that has seen plants as non-mechanic systems. This approach can use the concept of biological need as the primary holistic process in living systems. Demonstrating the similarity between the need and semiosis, it is concluded that sign is a meronomic entity. A distinction between five levels of sign systems is proposed: cellular, vegetative, animal, linguistic, and cultural. Vegetative sign systems are those which are responsible for the morphogenesis and differentiation within an organism, thus belonging to all multicellular organisms.

This article compares the methodologies of two types of sciences (according to J. Locke) — semiotics, and physics — and attempts thereby to characterise the semiotic and non-semiotic approaches to the description of ecosystems. The principal difference between the physical and semiotic sciences is that there exists just a single physical reality that is studied by physics via repetitiveness, whereas there are many semiotic realities that are studied as unique individuals. Seventeen complementary definitions of the semiosphere are listed, among them, semiosphere defined as the space of qualitative (incommensurable) diversity. It is stated that, paradoxically, diversity, being a creation of communication, can also be destroyed due to excessive communication.
