Chapter 37, Problem 3S
Summary Introduction
To describe:
The factors in the water and air that is necessary to be monitored while growing the lettuce hydroponically in the greenhouse.
Introduction:
The hydroponics is the type of culture, in which the plants are grown in water instead of the soil. The nutrients and water continually flow through the roots of the plants. This allows the regulation of the amount of nutrients supplied to the plants.

Make a simple HAND DRAWN sketch or flow diagram toillustrate the flow path of water through a plant, from the point of uptake from the soil totranspiration from the leaves. Ensure that you incorporate the following aspects in your sketch / diagram:• Water movement from the soil into the root, to the vascular tissues and the rest of theplant and into the atmosphere.• Label all the organs, tissues and structures involved in water uptake and transport.• Mention the mode of water movement (e.g. diffusion, osmosis, mass flow) whereapplicable along the symplastic and apoplastic pathways of water uptake and transport
Some seeds (tomato, for example) had been
germinated and the seedling grew for 2
weeks in soil, where the soil water potential
was maintained at -0.2 bars. The plants were
then divided into 5 groups and each group
subjected to a different soil water potential as
follows:
Group 1: 0 bars
Group 2: -0.03 bars
Group 3: -0.2 bars
Group 4: -3.0 bars
Group 5: -5.0 bars
At the end of three weeks at these various soil
water potentials, the plants that would have
made the least growth would be expected in
which group?
Question 11 options:
Group 3
Group 1
Group 2
Group 4
Group 5
Explain the three different ways water is moved from the soil, through the cortex, and then forced into to the stele of a root. Next, explain how water is moved from the roots up to the leaves.

- College 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_forwardEXPERIMENT : GRAVIMETRIC ANALYSIS OF PHOSPHORUS IN PLANT FOOD I want at lest 10 Precautions for this experimentarrow_forwardDraw a simple flow diagram or sketch to illustrate the flow path of water through a plant, from the point of uptake from the soil to transpiration and… (read in image below)arrow_forward

- 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?arrow_forwardExperiments usually have several controlled variables. These are variables that must be kept constant in all parts of an experiment. For example, if an experiment is testing the effect of sunlight on the growth rate of 5 seeds, the only variable that should change should be the amount of sunlight. All other variables should remain the same to ensure that sunlight is the only aspect affecting the results. The other variables, such as soil type, amount of water, type/amount of fertilizer, are the controlled variables. Looking back at the simulation experiment on the meteorite, describe two variables that should have been controlled.arrow_forwardExperiments usually have several controlled variables.
