Plant-Animal Adaptations Plants and animals often evolve by adapting to each other; for example, plants evolve defenses against herb ivory (animals feeding on plants).Spiny cacti, poisonous hemlock, thorny rosebushes, and prickly thistles are all familiar examples of defended plants. A more...
A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun’’s energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are ...
Cactus stems have a structure that other plants do not have: bumps called areoles. Botanists guess that areoles are most closely related to the branches of regular plants. It is from the areoles that both spines and flowers grow. One last important cactus survival strategy is to grow slowly...
as population genomics datasets enable us to: (1) perform genome‐wide association studies (GWAS) to find genes underlying adaptive phenotypic variations; (2) scan the footprints of selection across the genome to pinpoint loci under selection; and (3) infer the structure and demographic history ...
(such as nitrogen fixing bacteria and mycorrhizal fungi) to aid them in their quest for nutrients. Finally, some key biotic and abiotic constraints on root development and function in the soil environment are examined and some of the adaptations roots have evolved to counter such stresses ...

Plant breeding enhances biodiversity.Plant breedersof all kinds—full-time professionals, farmer-breeders, and dedicated amateurs—add to the stock of genetically diverse organisms by continually producing new and genetically diverse plant varieties with new, ecologically diverse adaptations. Such increased ...
