Chapter 37, Problem 3TYK
Summary Introduction
Introduction: Soil contamination (soil pollution) is considered as a part of land degradation. It is mainly caused by the existence of xenobiotic chemicals in the soil environment. Agricultural chemicals, industrial waste, and improper waste disposal contribute to major soil contamination. There are certain methods available for decontamination of the soil as well as water; for example, phytoremediation.

Which of the following explains why pea plants in high soil nitrogen conditions have
so few rhizobial nodules on their roots?
When there is already high soil nitrogen there is a very large cost to having
rhizobial nodules.
The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the
soil, so when there is already high soil nitrogen there is no advantage for the pea
plant to expend the extra energy housing the rhizobia.
The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the
soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia
to keep the nitrogen for itself.
When there is already high soil nitrogen there is no benefit to the plant to
having rhizobial nodules, which can rob the plant of the high nitrogen supplies
so that the rhizobia bacteria do not have to fix the nitrogen themselves.

She then planted onions in two soil treatments labelled as ANGAT and UNITY. After a week, SimpLENI noticed that her onions in ANGAT increased in number compared to that of onions in UNITY. She then hypothesized that the soil treatments affected the cellular division in the roots of onions contributing to the difference in yield. To prove this, SimpLENI prepared longitudinal sections of onion root tips. Support SimpLENI in her experiment and win the competition by answering the following questions:arrow_forward
