Sense Perception v. Sense
Still thinking about the sense in which plants sense things in their environment, ...
Of the psychic powers above enumerated some kinds of living things, as we have said, possess all, some less than all, others one only. Those we have mentioned are the nutritive, the appetitive, the sensory, the locomotive, and the power of thinking. Plants have none but the first, the nutritive, while another order of living things has this plus the sensory. If any order of living things has the sensory, it must also have the appetitive; for appetite is the genus of which desire, passion, and wish are the species; now all animals have one sense at least, viz. touch, and whatever has a sense has the capacity for pleasure and pain and therefore has pleasant and painful objects present to it, and wherever these are present, there is desire, for desire is just appetition of what is pleasant. Further, all animals have the sense for food (for touch is the sense for food); the food of all living things consists of what is dry, moist, hot, cold, and these are the qualities apprehended by touch; all other sensible qualities are apprehended by touch only indirectly. Sounds, colours, and odours contribute nothing to nutriment; flavours fall within the field of tangible qualities. Hunger and thirst are forms of desire, hunger a desire for what is dry and hot, thirst a desire for what is cold and moist; flavour is a sort of seasoning added to both. We must later clear up these points, but at present it may be enough to say that all animals that possess the sense of touch have also appetition.

See https://willga.llia.io/sea-of-segments/ and this Hackaday writeup by Dan Maloney:
The amount of information the humble seven-segment display can convey is surprising. There are the ten numerals, dead-ringers or reasonable approximations for about half the alphabet, and even a few not-quite-canonical symbols. But when you put 12,288 segments to work, you get all that and much more. ...
On Aristotle's terms, the question then is whether individual plants have apetition, and that is not clear, to me at any rate. See Learning by Association in Plants by Monica Gagliano, Vladyslav V. Vyazovskiy, Alexander A. Borbély, Mavra Grimonprez & Martial Depczynski.
We say that the same stuff is wind on the earth, and earthquake under it, and in the clouds thunder. The essential constituent of all these phenomena is the same: namely, the dry exhalation. If it flows in one direction it is wind, in another it causes earthquakes; in the clouds, when they are in a process of change and contract and condense into water, it is ejected and causes thunder and lightning and the other phenomena of the same nature.

That, therefore, for which any growth is impossible is solid. For growth naturally requires room, in which broadening and extension is possible. But stones, sherds and the like always occupy the same space, and neither grow nor extend. Again, there is in plants a secondary form of movement, as they also have a power of attraction which draws the moisture from the earth. In this attraction is a movement which takes place in space, and somehow the ripening is completed: for this reason small herbs are produced in one period of one day. This is not the case with animals; for the matter in animals is individual and peculiar. For there is no ripening possible, except that which depends on material in its own possession. But the matter of which the plant is composed is near to it, and consequently its creation is quicker. What is lighter in it is created and grows fast compared to heavy material.

We have explained the origin of streams and the cause rivers in our book on Meteorology. Therein we stated about earthquakes that they often disclose springs and rivers, which have not been visible hitherto, for instance when the earth is cleft by the vapour. We often find that springs and rivers join when an earthquake occurs. But this does not happen to a plant, because there is air in the fineness of its parts, and there is further evidence in that earthquakes do not occur in sandy places, but only in solid and dry soil, such as the soil in which rivers and mountains are. Earthquakes occur in such places because water and stones are solid, but to rise because of its lightness is part of the nature of hot and dry air. So when the parts of the air coalesce and gain the mastery, they exert pressure on the spot, and a violent evaporation issues from them. But if the place were thin, it would not come out in this way, but in the way in which it occurs in sand. For vapour does rise therefrom, but little by little and consequently no earthquake occurs. But this does not happen in all solid ground—I mean this gradual issue of air. For its parts when collected together can cleave the earth, and this is the cause of earthquakes in solid bodies.
