Question
Chapter 35.2, Problem 3BC
Summary Introduction
To determine: Whether plant cells differ from animal cells in terms of the structure of microtubules.
Introduction: Microtubules are microscopic, fibrous structures found in the cytoplasm of a cell. These structures form a network that acts as a mesh for the cytoplasm and other organelles. Microtubules are proteinaceous structures and perform the basic function of providing a mesh for the cytoplasm and support to the cell.

Dynamic instability causes microtubules to either grow or shrink. Consider a microtubule that is
in its shrinking phase. What must happen at the end of the microtubule in order for it to stop
shrinking and to start growing again?
Q1: The micrograph shows a group of cells from a plant.
Name the part of the cell labeled A and B|
State 2 ways in which you can tell that the cells in the micrograph are plant cells and not
animal cells.

At the leading edge, actin filaments form rapidly into bundles and networks that make protrusions and move the cell forward. At the rear, cell adhesions are broken and the tail end of the cell is brought forward. What provides the traction for moving cells? How does cell-body translocation happen? How are cell adhesions released as cells move forward?arrow_forward

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. Draw and label ONE cell on the provided drawing area of the next page and label using the labels below: CELL WALL, CHLOROPLASTS, VACUOLE, NUCLEUS (if visible) CPID 810186 10arrow_forward
