Question
Chapter 38.4, Problem 1CC
Summary Introduction
To predict: The portions of tracheids that would be and would not be visible after staining lignin.
Introduction: The vascular tissues present in the plant body can be visibly differentiated on the basis of their structure and molecular composition. For the microscopic analysis of plant and animal tissues, the sample is cut into thin sections to obtain a slice that contains only one or a few layers of cells

Mosses 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?
We observed onion (Allium) root tip through the light microscope. We were asked "Was your onion root tip actively growing prior to being preserved?" What should I expect to see if it was actively growing?
Look at as shown. Vascular cambium is not present; it was located far above the top of the micrograph, but you can see there are six rows of wood cells. How many fusiform initials were involved in producing the wood visible in this figure? Look at all the cells in any particular row. Were all the cells of that row made by divisions of one fusiform initial or by many different fusiform initials?

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 phloemarrow_forward

Leaf A has a waxy cuticle on the upper epidermis and stomata on the lower epidermis. Leaf B a waxy cuticle on the upper epidermis and a lower epidermis covered with petroleum jelly. Both leaves were cut from the same plant. i)Explain why it is important for the leaves to be cut from the same plant. (ii) List TWO variabes that must be kept constant in this investigation. iii) Table 6 shows the results obtained in the experiment: leaf and test tube weight final weight change in weight A 40.7 39.9 0.8 B 38.7 38.7 0.0 Explain why the weight of set up A, decreased. iv) Using your biological knowledge, indicate how results will change, if a fan is switched on near the experimental set up.
