Question
Chapter 10.1, Problem 1CS
Summary Introduction
To determine: The model for the secondary wall of the plant in which the colors of the layers reflect the timing of their synthesis with reference to figure 10.6 given in the textbook.
Introduction: The synthesis of the secondary cell wall of the plants occurs after the formation of the primary walls. The secondary cell wall is deposited and synthesized between the plasma membrane and the primary cell wall after a plant cell matures and eventually stops to divide.

5. Chloroplasts are organelles that are found in plant cells. Some plant tissue
contains cells with large numbers of chloroplasts, while other tissue contains
few chloroplasts.
Based on the function of chloroplasts, which type of plant tissue is
likely to contain cells with many chloroplasts?

Which of the following statements correctly describes how the prokaryotic cells appear compared to the eukaryotic cells under the microscope? The prokaryotic cells are much smaller than the eukaryotic cells. The prokaryotic cells have a nucleus, while the eukaryotic cells do not.

The prokaryotic cells have cytoplasm, and eukaryotic cells do not.arrow_forwardQ2: Each of the following statements contains at least one error. Decide what is wrong with each statement and rewrite it correctly. a. Plant cells do not burst in pure water because the cell stops wvater getting into the cell. b.

TYPICAL PLANT LEAF CELL (Western Pond Weed): Pond weed is a great plant for studying plant cells, because the leaves are only two cells thick and it is easy to make mounts and view the cells under the microscope. Use the "close the book" method to make a wet slide of one pond weed leaf. The instructor will demonstrate the procedure. Place the slide on a compound scope and use the "stair- step" procedure to focus on a few cells of the leaf at high power. You should definitely be able to see cell walls and chloroplasts. Rarely, you may see a nucleus. In some of the cells, you may notice that the chloroplasts are moving. They seem to cycle around the center of the cell. This is called cyclosis, and is caused by the cytoplasm streaming around the vacuole carrying some organelles with it.
