You are asked to take care of your
teacher's favorite plant while she goes on
a research trip. She leaves a set of
special macronutrients supplement that
you can apply to the plant while she's
gone.
While in your care, you notice that the
plant has distinctive yellowing leaves
while the veins remain green.
Which supplement would most help this
plant?
Select one:
O a. Magnesium
O b. Phosphorous
O c. Nitrogen
O d. Sulfur
e. Calcium
For an element to be regarded as essential, all of the following criteria must be met, except: a. No other element can perform the function. b. The element is directly involved in plant nutrition. c. The element is inorganic. d. The plant cannot complete its lifecycle without the element.
An experiment was conducted to determine the deficiency symptoms of tomato plants placed in a hydroponic solution. Six bottles were prepared, and each bottle, except for the positive control, lacked a certain micronutrient. In the positive control, all nutrients were provided. Unexpectedly, the control setup still showed symptoms of micronutrient deficiency. It was then discovered that the relative humidity in the room was very high and transpiration was affected.
Explain the appearance of these symptoms in the positive control set-up in lieu of the importance of transpiration? How will thermoregulation of tomato plants be affected if transpiration will not occur?

- Name the nine required macronutrients and the seven required micronutrients of plants.arrow_forwardCollege students have conducted an experiment to determine the deficiency symptoms of tomato plants that is placed in a hydroponic solution. Each bottle out of the six bottles except for the positive control has lacked a certain micronutrient. In the positive control, all the nutrients were provided. However, the control setup showed symptoms of micronutrient deficiency unexpectedly. College students later found out that the room has a very high relative humidity and the transpiration was affected. Theoretically, how will the thermoregulation of tomato plants be affected of transpiration will not occur?arrow_forwardYou are shopping for fertilizer for your new tomato plants in your garden. You have a choice between a name-brand fertilizer and a generic-brand fertilizer, which are both in liquid form. The labels indicate that they are identical in composition (the type of nutrients and their amount per unit volume of fertilizer are identical). The name-brand fertilizer advertises that it is superior to any other fertilizer on the market. To test the claims of the two fertilizers you decide to buy one bottle of each and treat equal numbers of "Big Boy" tomato plants (a single type of tomato that goes great with salads) with the same amount of each fertilizer for the entire growing season. Using the information from the paragraph above, which of the following is an example of a controlled variable in your experiment? A) growing the same type of tomato plant B) using the same amount of fertilizers C) using 2 different fertilizers D) growing the same type of tomato plant and using the same amount of…arrow_forward
- A study in wheat fields showed that high levels of carbon dioxide in the atmosphere impair the absorption of nitrate by plants. Consequently, the nutritional quality of these foods may decrease as the levels of carbon dioxide in the atmosphere reach estimates for the coming decades. In this context, the nutritional quality of the wheat grain will be modified primarily by reducing which element?arrow_forwardThroughout history, spices have been used as preservatives and to cover up the smell or taste of food that is slightly spoiled. The success of some spices led to a magical, ritualized use, and possession of spices was often limited to priests or other powerful members of the community. a. Choose a spice and trace its use geographically and historically. What is its common use today? b. Spices grow and tend to be used predominantly in warmer climates.

- Answer the following: a. What is a nutrient cycle? b. What are the different types of nutrient cycles, and describe each briefly. c. What is the importance of the different nutrient cycles on Earth?arrow_forwardCamellia and azalea are plants that produce yellow leaves, which is considered an undesirable outcome, when they are grown on alkaline soil. Which of the statements below support the fact about camellia and azalea stated above? a. Loam soil is not advisable to be used in growing camellia and azalea because of its acidity. b. Camellia and azalea should not be planted in chalk soil. c. Camellia and azalea produced yellow leaves because they are planted in acidic soil. d. Camellia and azalea require chalk soil to counter the effect of the alkaline soil used.arrow_forwardPlants make their own essential elements to complete their life cycle. We have figured out which elements are essential by using hydroponic culture, which involves growing plants in clay instead of soil. Micronutrients of plants include carbon, oxygen, and hydrogen. Plants only require a small amount of macronutrients which include zinc, copper, and iron. There are 4 mistakes in this paragraph, rewrite it to be correct.arrow_forward
- Macronutrients provide us the energy to live, move, and function. Evaluate the sentence above, reviewing how Bioenergetics works (i.e., food energy production). Explore energy source, transfer, utilization, and storage including micronutrients and water.arrow_forwardWhat are the differences between macronutrients and micronutrients? Macronutrients are good , micronutrients are bad. Micronutrients are a source of protein, macronutrients are a source of vitamins Macronutrients consist of minerals , micronutrients consist of water. Micronutrients do not provide calories , macronutrients provide calories. Previous PageNext Pagearrow_forwardAs scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input. The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres. What was the estimated energy input of the grass? A. 2 kcal × 106 B. 4 kcal × 106 C. 8 kcal…arrow_forward
