Plant Cells have a cell wall and animal cells do not. Plant Cells have a larger vacuole than an animal cell. Plant cells have glyoxysomes. Plant cells contain chloroplasts which are used for photosynthesis.
The outer most boundary of plant cell is cell wall. The outer most membrane of the animal cell is cell membrane. In plant cell, cell membrane lies inside the cell wall. Plant cell contains chloroplast but animal cell does not contain chloroplast. Chloroplast helps plants in photosynthesis to prepare food. Animal cell contains numerous small vacuoles present in the cytoplasm of cell but plant cell has a large vacuole present at the center of plant cell. Plant cell is rigid or more structured as compared to animal cell because of the presence cell wall in plant cell.
The survey population is 60, but 8 read no magazine, so 60-8=52 people read at least 1. 25 read Newsweek and 26 read Times, but 11 read both of those, so a total of 25+26-11=40 read either Newsweek or Times. If 40 read Newsweek or Times, then there are 52-40=12 readers who read only Fortune. Similarly, 26 read Times and 26 read Fortune, but 8 read both, so 26+26-8=44 read Times or Fortune. Thus 52-44=8 read only Newsweek. Likewise, 25 read Newsweek and 26 read Fortune, but 9 read both, so 25+26-9=42 read Newsweek or Fortune. Thus 52-42=10 read only Times. 25 read Newsweek, but 9 of them also read Fortune or all three, and 8 of them read only Newsweek. This leaves 25-8-9=8 who read only Newsweek and Times, but not all three. Since 11 read Newsweek and Times (and maybe Fortune), 11-8=3 readers read all three.
3 read all three publications. 8 read only Newsweek, 10 read only Times, and 12 read only Fortune, so 8+10+12=30 readers read only one publication.
