- 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 didYou place a flaccid plant cell (Ψ = -0.7 MPa) into an environment (beaker) of pure (deionized) water (Ψ = 0 MPa). Compare the initial conditions of the flaccid cell and the environment (beaker of pure water) in terms of: G) Predict the direction of water movement (into the cell, out of the cell, or no net movement) H) Predict the change in turgor pressor of the cell (increase turgor pressure or decrease turgor pressure) I) Predict the fate of the cell (plasmolyzed, turgid, or lysed)The figure attached shows an open stoma during a gaseous exchange process in a plant. A) What is 'y'? B) Elaborate the gaseous exchange process in plants by considering the influence of 'y' on the turgidity of guard cells.
- A team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 μmol, and Groups 3 and 4 were exposed to 500 μmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below. Group 1(200 μmol, no P) Group 2(200 μmol, + P) Group 3 (500 μmol, no P) Group 4 (500 μmol + P) Average Dry weight (g) 0.8 1.1 1.5 6.2 Describe the effects of light and phosphorous on the growth of the plants in this study.

- If you wanted to study the effects of soil moisture and light intensity on the growth of soybeans and required a high ability to regulate these independent variables, what type of experiment would you choose?Imagine an experiment where I am testing the effects of salt on the growth of corn plants. I set up several treatments where some plants get no salt, some are watered with a 0.05% salt solution, and some are watered with a 0.1% salt solution. I use the same species of plants, the same soil, and the same total amounts of water in my experiment. Every other day I record the height of the plants in cm. What is the independent variable in my experiment? What is the dependent variable in my experiment? What is the control treatment in my experiment? What are three controlled variables in my experiment?In this field of sunflowers, variation exists. Some flowers are tall, others short, and finally some plants are an intermediate height. The tallest plants shade the shorter; the taller plants are pollinated first. Over time, we might expect this field of sunflowers to be mostly tall. According to this scenario, we would classify the production of the sunflowers in what area of this Venn diagram? A) A. Reactivate B) B. Reactivate C) C. D) D. Reactivate
- SimpLENI 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. Support SimpLENI in her experiment and win the competition by answering the following questions:An experiment is conducted to determine the effect of classical music on the growth rate of marigolds (flowers). Two groups of plants are grown from seed in identical soil types, exposed to identical light conditions, and given the same nutrients. Group A is in a quiet atmosphere. The plants in group B provided with the same atmosphere, except that classical music is played for twelve hours daily in this area. The scientist measures the plants in both groups each day and records the data. In experimental design, Group A is known as.* experimental group control group non-experimental group O quasi-experimental groupWhich 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.
