While exploring a forest, you come upon a plant that you haven't seen before. You dig it up and take it back to your lab for further inspection. Back at the lab, you observe the characteristic structure of the plant and make some notes. Then, you carefully dissect the stems and leaves and look at the tissue under the microscope. Finally, you are able to determine the type of plant it is.
Use the notes below to identify the class to which this plant belongs.
Notes on physical characteristics of the specimen:
the plant has no leaves or roots, but has hair-like rhizomes which anchors it in the soil
the stems are highly branched
sporangia are present at the ends of each stem
dissection of the stem shows the presence of vascular tissue in the form of a xylem and phloem
You are responsible for landscaping a very large urban park. You choose a popular flowering garden plant, the hydrangea, to plant throughout the park. The nursery you purchased the plants from said that the flowers should be pink. After a few months, though, you find—to your surprise—that the plants throughout the park display a variety of flower colors ranging from purple and blue, to pink and white, and finally, to all shades in between.
After a suggestion from a friend, you test the soil where each plant was planted, and you determine that the color of the flowers seems to correlate with the acidity of the soil in which the plant was placed.
Choose the answer that best fits the blank. The parentheses after the blanks are the choices.
Since the flowers have shown such a broad range of colors, with no clear distinction between one color type and the next, this is an example of _________ (continuous variation, codominance, pleiotropy). The acidity of the soil is an example of…
a botanist wants to see how different colored light waves influence the growth of pea plants. she puts the same number of seeds into three identical pots with the same kind and amount of soil. she then gives them the same amount of water every 3 days for the length of the experiment. one pot is placed into a dark windowless closet. another part is left on the window sill, and the third is placed under a lamp with a green bulb. she records the height of each plant every day for 3 months what is the independent variable in this experiment.

- In your yard, you find a new weed has popped overnight that you haven't seen before and you are trying to identify it. It has a pretty little red flower with six petals and parallel leaf veins. You cut open one of the stems and notice that it has vascular tissue scattered throughout the stem in an unorganized manner. You know immediately that this is a dicot. an angiocot. a monocot. a eudicot.arrow_forwardWhat is the description of the flower of the banana (Musa acuminata)? Based on the given text.arrow_forwardEngineers have designed a smaller version of such a container that can be used to seal off a small part of the plant. One version of this device, called a leaf chamber, is shown below. When a scientist uses this device on a plant, they don’t need to break the leaves off the branch or stem they are attached to. The leaf chamber makes an airtight seal around the stem or branch even though it is sticking out of the chamber. Using this device, scientists detected the most change in O2 and CO2 levels inside the chamber when a leaf is in the chamber. They only detected a small change in O2 and CO2 levels in the chamber when a green stem was placed in the chamber. No change was detected when a root or a brown stem was placed in the chamber. Why do you think a scientist would prefer not to remove the leaves from a tree or a plant in order to take these sorts of measurements?arrow_forward
