Textbook Question
Chapter 1, Problem 1.2PS
QUANTITATIVE Cell Sizes. To appreciate the differences in cell size illustrated in Figure 1-3a, consider these specific examples. Escherichia coli, a typical bacterial cell, is cylindrical in shape, with a diameter of about 1 μm and a length of about 2 μm. As a typical animal cell, consider a human liver cell, which is roughly spherical and has a diameter of about 20 μm. For a typical plant cell, consider the columnar palisade cells located just beneath the upper surface of many plant leaves. These cells are cylindrical, with a diameter of about 20 μm and a length of about 35 μm.
(a) Calculate the approximate volume of each of these three cell types in cubic micrometers. (Recall that V = πr2h for a cylinder and that V = 4πpr3/3 for a sphere.) Use three significant figures for these calculations.
(b) Approximately how many bacterial cells would fit in the internal volume of a human liver cell?
(c) Approximately how many liver cells would fit inside a palisade cell?

Match the following organelles to their function or analogy.
1. The
stores the DNA for the eukaryotic cell.
2. The
can be smooth or rough and may be a site of manufacture of proteins or transport of various materials in a eukaryotic cell.
3. The
is found mostly in plant cells and creates food (stored energy) using sunlight.
4. The
packages up different proteins or other materials and sends its packages all over the eukaryotic cell.
5. The
manufactures proteins in all cells.
6. The
is a rigid exterior protective part of the cell that gives it shape and is not found in all cells.
7. The
transports things throughout the eukaryotic cell and sometimes out of the cell.

- Part A - Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures. In this activity, you will indicate which cell structures are found only in plant cells, only in animal cells, or in both plant and animal cells. Drag each cell structure to the appropriate bin. If a structure is found in both plant cells and animal cells, drag it to the "both" bin. ► View Available Hint(s) chloroplast plant cell only cellulose cell wall mitochondrion endoplasmic reticulum nucleus animal cell only central vacuole plasma membrane Golgi apparatus both centriole Reset Help cytoskeletonarrow_forwardasap please.arrow_forwardCELL STRUCTURE AND FUNCTION – EUKARYOTES, PROKARYOTES AND VIRUSES-LABORATORY REPORT SHEET ACTIVITY 2: CELL MEMBRANES, OSMOSIS AND DIFFUSION Initial Volume (Vi) (mL) Final Volume (Vf) (mL) Change in Volume (Vi – Vf) (mL) A 20% sucrose 20% sucrose 92.0 mL 94.0 mL -2.0 mL B 40% sucrose 20% sucrose 92.0 mL 92.0 mL 0.0 mL C 20% sucrose 40% sucrose 92.0 mL 90.0 mL 2.0 mL Treatment Percent Change A -2% B 0% C 2% Hypothesize which dialysis bags should gain, lose or stay the same in regards to volume.
