Question
Chapter 23.1, Problem 2MC
Summary Introduction
To determine:
The way in which planting nodule-producing legumes be useful in crop rotations.
Concept introduction:
The bacteria use nitrogen fixing enzymes which converts the N2 to NH4+ (ammonium ions). The bacteria live in symbiotic association with plants, as they consume sugars produced by the plants during photosynthesis and in return, the bacteria fixe nitrogen for the plant tissues.

How can tissue culture techniques be used to study the effects of environmental factors, such as temperature, humidity, and light intensity, on the growth and development of plant cells and tissues, and how can this knowledge be applied to improve crop yields and plant resistance to abiotic stress?
Discuss the importance of determining the mechanical properties of crops. Cite examples.
The following experiment was carreid out at ILC Laboratories to measure the effect of different nutrient solutions on bean root growth. Three nutrient solutions were made:
1.) A solution containing all required nutrients
2.) A solution containing all required nutrients except nitrogen; and
3.) distilled water.
The results recorded for root length and leaf colour were as follows:
Solution 1.) 47 mm; deep green
Solution 2.) 17 mm; pale green-yellow
Solution 3.) 14 mm; pale green-yellow
a.) explain how the solution ranked in relation to the other two;
b.) state the evidence that supports your answer; and
c.) explain why the plant grew the way it did

- In producing seeds, what specific method is being done?arrow_forwardSimpLENI will be competing in a Lugaw Cooking Competition in May. She will be using onions as a special ingredient and garnish in her recipe. 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.
