Why are bubbles counted in this experiment, and what do they represent?
make a line graph showing the difference in the number of oxygen gas bubbles released by the plant under different light intensities and water temperatures.
Which light intensity and water temperature caused the plant to produce the most amount oxygen gas during the process of photosynthesis? Why
Which light intensity and water temperature caused the plant to produce the least amount oxygen gas during the process of photosynthesis? Why?
This apparatus was used by a student, in a brightly lit room, to measure the rate of water
loss from a leafy shoot. He measured how far the bubble moved in five minutes. He
measured this three times.
The results are shown in the table.

- Students filled three identical flasks with water and placed elodea, a type of aquatic plant, in each flask. The students adjusted the light intensity that each plant received by wrapping some of the flasks in either screen mesh or foil. The screen mesh allowed only some light to pass through, and the foil allowed no light to pass through. The students recorded the amount of dissolved oxygen, in milligrams per liter, in each flask at the start of the experiment and after twelve hours of light exposure. The data are shown in the table. Drag a label corresponding to a treatment to the correct column header in the table to indicate the beaker from which each piece of data was most likely collected.

Explain.arrow_forwardMosses are very good at absorbing water. Peat moss, also known as sphagnum moss, is particularly good at holding water, which is why it is often used in horticulture to improve soil structure and drainage. If you made a wet mount of a sphagnum moss leaf on a microscope slide and observed it with a compound light microscope, it would look like the image on the right. In that image of the magnified leaf, label a water-holding cell, the location of photosynthetic cells, and a reinforcing rib. 5) How do mosses survive without vascular tissue?arrow_forward

Tim is observing xylem vessel elements under the microscope. He initially used the low power objective (LPO) to search for the vessel elements formed in his specimen (Fig.3 A), he. He then wanted to see the vessel elements in greater detail, so he used the high power objective (HPO). Although he didn't have any trouble in resolving the vessel elements using the HPO he wanted to try using the oil immersion objective (OI0). He noticed that he needed to use the fine adjustment knob to focus at two different groups of vessel elements one at a time (Fig. 5 B and C). He also noted that he cannot completely resolve the specimen under the O10 when it should appear clearer as shown by his instructor previously. A B Figure 5. Vessel elements developed from cassava pith in response to synthetic plant hormones under LPO (A) and O10 (B and C). a.
