The organism is made up of molecules which are analogous to them.
Any organism may pass through a series of free-living larval stages.
The cell-walls of plants render the entry of solid material into the organism impossible.
Every organism takes origin from a parent organism of the same kind.
An organism was to him something controlled by a formative organizing principle.
The nodules on the roots of leguminous plants are induced by the presence of a minute organism now known to do no injury to the plant.
It is within common observation that parent and offspring are alike: that the new organism resembles that from which it has come into existence: in fine, biogenesis is homogenesis.
In the former case the nature of the organism is such that it yields readily, when subjected to certain conditions, and all or nearly all the individuals become modified in the same way.
He looked on the actions of the individual organism and of society as determined by the needs of self-preservation.
This method of study has to a large extent modified our ideas of the relative importance of the parts of such an organism as a large tree.
The organism is largely dependent for its vital processes upon gaseous interchanges.
Their cells during the period of incubation of the symbiotic organism are abundantly supplied with starch.
The conjoined organism is, in fact, a colony or association of the protoplasmic tinits, though each unit retains its independence.
The heat attendant on these actions, and on the vital processes of the animal organism, naturally first attracted attention.
In some cases the zoogloea thread or tube has not been seen, the organism consisting entirely of the bacterioids.
It is an integral part of an individual organization and as such the exercise of its functions must be governed by the organism as a whole.
That the fixation of the gas is carried out by the fungal organism either in the soil or in the plant, and the nitrogenous substance so produced is absorbed by the organism, which is in turn consumed by the green plant.
In spite of the statement that the nature of the organism is the most important factor in variation, the tendency amongst evolutionists has been to take much more account of the influence of external conditions.
