Scientific models must be able to generate PREDICTIONS.
Scientific models refers to frameworks, which are used to elucidate and predict the behavior of an object or a system. Scientists usually use models to carry out research and to explain the results of their research. A good and effective scientific model should be able to make accurate predictions.
Answer and Explanation:
The cell was placed in a hypertonic solution. Glucose is a monosaccharide while starch is a polysaccharide. The concentration on the outside is higher compared to that on the inside. The cells have cell membrane that is semi-permeable.
Movement of molecules is dependent on the concentation gradient. However, the size of molecules determine the diffusion rate. Small and light molecules diffuse faster than large and heavy molecules thus glucose diffused faster than starch.
The cell membrane being permeable suggested that it allows molecules of small sizes to pass but not large ones.
No. The recorded drop in water in the pipet of the potometer would have been used not only for plant transpiration, but also to return the plant cells to a turgid state. Turgid means to expand<span> due to high fluid content. Plants are required to maintain turgid cells to maintain an upright position as loss of turgidity results in plant wilting.</span>
