Describe the situation as unnecessarily cruel to kill animals for food when human beings can survive and thrive off of a diet consisting of only plant materials.
A desirable biotechnological breakthrough would be to modify or simplify lignin structure in plants consisting of only one rather than three phenol alcohols or to simplify the complex, recalcitrant interunit linkages separating the lignin monomers.
There were both mature plants and juvenile weeds consisting of only cotyledons, as well as 5 different weed seeds.
Above the surface, the plant life of the cays is very restricted, consisting of only some 30 to 40 species.
This makes sense, as the complete-case cohort consisted of only 11 plants with little heterogeneity in this variable.
Fossilized hyphae and spores recovered from the Ordovician of Wisconsin (460 Ma) resemble modern-day Glomerales, and existed at a time when the land flora likely consisted of only non-vascular bryophyte-like plants.
The pitcher plant family Cephalotaceae (order Oxalidales) consists of only the Western Australian pitcher plant (Cephalotus follicularis).
In natural environments, cellulose which consists of only glucose is a shared component of all types of plant biomass, yet distinct types of hemicelluloses (e.g. xylan, glucuronoxylan, arabinoxylan, glucomannan or xyloglucan) which consists of many different monosaccharides are found in different plants or plant tissues.
Some plants, such as willows and squashes, have flowers that consist of only one sex, though most have both male and female parts on a single flower.
