Not illustrated. 1872 Excerpt: ...the individual perishes. 3. Functions of Relation, comprising all those functions, such as sensation and locomotion, whereby the organism is brought into relation with the outer world, and the outer world in turn reacts upon the organism. In plants the functions of relation are reduced to their minimum, and hence these functions are often spoken of as the Animal functions; whilst the functions of nutrition and reproduction, as being common to all organisms, are grouped together under the name of the Organic or Vegetative functions. Plants, however, are by no means wholly destitute of the functions of relation; and, curiously enough, these functions are most developed, or, at any rate, most conspicuous, in some of the lowest members of the vegetable kingdom, which have on this account been mistaken for animals. In plants we observe the same specialisation of functions that we have formerly seen in animals, in ascending from the lowest forms to the highest; but, as in animals also, there is an apparent reversal of this law in some cases as far as the functions of reproduction are concerned. The processes, namely, by which a young Exogen is produced, are apparently less complex than those by which many of the Cryptogams are perpetuated, just as the reproduction of a Vertebrate animal is in one way a simpler matter than that of a Hydroid Zoophyte. In all these cases, as we shall see, the essential part of the process consists in the bringing together of a germ-cell or ovum and a sperm-cell or spermatozoid; and so far as the process of bringing together is concerned, the complexity is certainly on the side of the lower form. It may be said, also, that there are no essential or fundamental characters by which the ova and sperm-cells of the higher form can be dist...
