Question
Chapter 2, Problem 8RQ
Summary Introduction
To determine:
The true statement about lysosomes.
Introduction:
Cytoplasm is the region of the cell present between the cell membrane and the nuclear membrane. Cytoplasm includes cytosol, cell organelles, and inclusions. Cytosol is the fluid of the cell where all the cell organelles are present and it further includes enzymes, ions, and other molecules required by the organelles to perform their functions.

Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1 um. The scale bar works in the same way as a scale on a map, where, for example, 1 inch equals 1 mile. In this case the bar represents one thousandth of a millimeter. Using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. Start by measuring the scale bar and the diameter of each cell. The units you use are irrelevant, but working in millimeters is convenient. Divide each diameter by the length of the scale bar and then multiply by the scale bar's length value to give you the diameter in micrometers.arrow_forward1) All of the following are functions of proteins within a membrane except __________.
