The underlined se constructions in this extract are ‘se pasivas’ which is a type of construction characteristic of the scientific genre. As Di Tullio explains, the subjects of passive voice sentences with se are made up of inanimate nouns. In this case, the patient ,which is the syntactic subject, is a cell. As it has been previously stated, this extract is from the scientific genre, therefore, the agent is understood from the deictic context. We translate the se pasivo constructions in Spanish INTO a participial voice in English, in which also the agent would be omitted as it is not relevant to the text.

In middle constructions, the agent is implicit, and the subject is always located in preverbal position.

The type of verbs that predominate are verbos intransitivos ergativos o inacusativos, i.e., verbs whose subject performs the thematic role of patient or theme. In the text there are cases of se diacrítico as in “corresponderse”, “encontrarse”, “presentarse” and “destacarse”, cases of se intransitivizador as in “invertirse”, “completarse”, “depositarse” and “desarrollarse”, and, finally, cases of se recíproco as in “relacionarse”, in both instances. The predominant type of “se” in the text is se diacrítico, whose presence yields the existence of two lexemes, one that is pronominal and another one that is not. Another type of “se” found in the text is se intransitivizador, which affects the realization of the argument structure of the verb, as the external argument is “absorbed” by the pronominal “se”, while the internal argument is syntactically expressed as the subject. In the case of se recíproco, “se” is used as a reciprocal pronoun that denotes a mutual interaction between the two subjects (there must be more than one entity acting as subject as a requirement). In all cases there are pronominal constructions at stake because “se” is used as a pronominal.

The sentence in a) is acceptable in English as an example of middle voice, middle construction. Although there is no generic interpretation for the syntactic subject “she” points to a specific person and not people in general. The stativized verb “photograph” attributes a certain property to the externalized argument “she” plus a modalizing adverbial “well” that emphasizes the attribute and facilitates the situation represented in the verbal form. One possible interpretation may be: “it is easy, for everyone, to photograph her”. Sentence b) is acceptable because, unlike sentence a), it does not attribute a property of the Patient, but rather describes a happening/occurrence that took place in the past. In this case, “it” is the externalized argument, the syntactic subject in the middle voice, while the Agent is selected for by the verbal predicate, but it is implicit.

The sentence in a) is acceptable in English as an example of middle voice, middle construction. Although there is no generic interpretation for the syntactic subject “she” points to a specific person and not people in generalLG. The stativized verb “photograph” attributes a certain property to the externalized argument “she” LG plus a modalizing adverbial “well” that emphasizes the attribute and facilitates the situation represented in the verbal form(1). One possible interpretation may be: “it is easy, for everyone, to photograph her(2)”. Sentence b) is acceptableX because, unlike sentence a), it does not attribute a property ofLG the Patient, but rather describes a happening/occurrence(3) that took place in the past. In this case, “it” is the externalized argument, the syntactic subject in the middle voice, while the Agent is selected for by the verbal predicate, but it is implicit.
1) Careful with ML here. The notion of "facilitator" of the situation represented by the verb is associated with the properties that the Subject is said to possess. In turn, this notion is further made explicit by the modalizing adverbial.
2) Therefore, this would not be an instance of a canonical middle construction, for what is in focus is a specific individual and not a type or a class of individuals. In any case, your explanation is valid and you could argue that, although not prototypical, this is an instance of a middle construction (in which the verb appears in middle voice).
3) Yes, but note this event cannot take place spontaneously, the verb "to build" cannot be used in middle voice intransitively, ergatively, it should have been "it was built well"

(1)The type of verbs that predominate are verbos intransitivos ergativos o inacusativos, i.e., verbs whose subject performs the thematic role of patient or theme(2). In the text there are cases of se diacrítico as in “corresponderse”, “encontrarse”, “presentarse” and “destacarse”, cases of se intransitivizador as in “invertirse”, “completarse”, “depositarse” and “desarrollarse”, and, finally, cases of se recíproco as in “relacionarse”X(3), in both instances. The predominant type of “se” in the text is se diacrítico, whose presence yields the existence of two lexemes, one that is pronominal and another one that is not. Another type of “se” found in the text is se intransitivizador, which affects the realization of the argument structure of the verb, as the external argument is “absorbed” by the pronominal “se”, while the internal argument is syntactically expressed as the subject. In the case of se recíproco, “se” is used as a reciprocal pronoun that denotes a mutual interactionX(4) between the two subjects (there must be more than one entity acting as subject as a requirement). In all cases there are pronominal constructions at stake because “se” is used as a pronominal.

1) Although we could argue, as you do, that some instances of these verbal forms belong to "se diacrítico", there is a common denominator in all of them, which is that they represent occurrences, happenings, that take place spontaneously without the intervention of an agent. Thus, we could argue that, having this perspective into account, most of them (except for "corresponderse") can be considered instances of "se intrasitivizador".

2) And there is no agentivity involved.

3) Incorrect: consider that "se recíproco" entails the use of a transitive, agentive, verb, which is not the case here.

4) Incorrect. Consider that if you apply the paraphrase test, the "se" is maintained in the paraphrase, which proves this verb is not "recíproco".

Sentence E is an acceptable middle voice construction, given that the transitive verb "open" shows an active morphology by agreeing with the syntactic subject "window", which, in fact, would be the internal argument of an active construction.  Furthermore, this sentence includes an adverbial modifier , "easily", which is required for the middle construction to be acceptable. In consequence, this construction describes a property of the window: it opens easily.
Sentence F is unacceptable in English, because although there is a transitive verb, "cook", and a direct object which has been promoted to function as syntactic subject ("the pasta"), middle constructions are not compatible with progressive tenses because of their non-eventive, habitual interpretation. In addition, this cannot be considered a passive contruction either, because the verb ("cook") shows active morphology. Finally, the realization of the agent through the by-phrase ("by the chef"), would be acceptable if this sentences was a passive contruction.

re: sentence F. You are right, it's a middle construction and you may claim it's not a "standard" one as what is in focus is not a type/class of entity/individuals
re: sentence G. You can just add that middle constructions do not allow for agents to appear explicitly

The underlined constructions in the text show the employment of syntactic subjects (ameloblastos, microvellosidades, vesículas) that perform the semantic role of patients. These subjects are in pre-verbal position. The  verbs appear in active morphology and show the addition of the pronoun "se"; they are transitive verbs of action  that select a direct object in the prototypical sentence. However, in this text, they lose the agentive actional character and become states. There is an spontaneous change of state caused without the intervention of a human agent, that is, the process takes place by itself, and there is not a specific time reference since there is "temporalidad neutra". Considering this, the grammatical structure that predominates in the text is a canonical middle construction.
