Study with Quizlet and memorize flashcards containing terms like plants that can make their own food from inorganic raw materials, such as carbon dioxide and water, through photosynthesis in the presence of sunlight, plants that are totally parasitic and lacking in chlorophyl, plants that are unable to synthesize organic carbon and draw all of their nutrients from the host plant and more.
Plants are unique organisms that can absorb nutrients and water through their root system, as well as carbon dioxide from the atmosphere. Soil quality and climate are the major determinants of plant distribution and growth. The combination of soil nutrients, water, and carbon dioxide, along with sunlight, allows plants to grow.
The most important source of BNF is the symbiotic interaction between soil bacteria and legume plants, including many crops important to humans (Figure 31.9).The NH 3 resulting from fixation can be transported into plant tissue and incorporated into amino acids, which are then made into plant proteins.
Most of the increase in mass in the mother occurs after 50–60% of the gestation period has elapsed. The water content of the developing fetus also decreases while the fat, protein, and mineral content increase during gestation. The mammalian newborn, or neonate, averages 12.5 ± 2.3% protein and 2.7 ± 0.8% ash at birth.
Plants adapt to nutrient deficiency or toxicity stress by altering multiple physiological, biochemical, and molecular processes, which are manifested in their mor-phological responses. While this issue emphasises the plant’s mechanisms to adapt to nutrient stress, including deficiency and toxicity, the individual articles present ...
