Answer:
a topic that interests you and you have read about it. The information should be used to derive possible answers to what you would like to research on. It can also be found in books from the library and online. Pick a topic that you’d like to know more about. Selecting an interesting topic helps you to generate hypothesis before the study. For example, choose a topic like, why is the percentage of obese women is larger than that of men? This is a topic that may raise a discussion, and the literature of this information will vary. The information in books written by different people will be different.
Explanation:
Answer:
1) pathway taken by water
water is absorbed from the soil, through the root hair cells and is transported by the xylem vessel up the stem to the leaf and/or flowers. From the leaf, some water is lost to the atmosphere as vapors escape out through the stoma present in the lower epidermal layer of the leaves.
2) water potential gradient
water potential refers to the concentration of water present. A gradient forms when there is a difference between the concentrations of water in two regions separated by a partially permeable membrane.
Hence, water moving down a water potential gradient means that it goes from a region of high water potential to a region of low water potential.
3) There are tiny openings on the lower side of the leaves called as stomata (plural: stoma) that allow for gaseous exchange to occur. These openings are controlled by guard cells which are open during the day and close during the night.
Hope that answers the question, have a great day!

Explanation:
These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.
Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.
