HW # 47- Review your Venn Diagram, Comparing a Cell to a Factory worksheet. Make sure that you have written your best answer.
Warm up Please put last week’s warm up in the center of your table.
Name some things that humans produce (make). Where are they made? How are they made (by hand, by machine, etc.)
Week 14, Day One
Goals for Today
• Complete the “Two Lab Conclusion”
• Use your iPad to view the A Cell is Like A Factory power point.
• Answer the questions on the Comparing a Cell to a Factory worksheet.
Using what you learned from Thursday’s Plant/Animal lab AND Friday’s ipad study, write a two day lab conclusion. In class, we have been studying _________________. Specifically, we have been focusing on the difference between plant and animal cells. Before beginning yesterday’s lab, I thought that plant and animal cells were different because ___________. I also that they were similar because _________________. Throughout the course of the activities, I did a lot of observing. I observed __________. I was doing this to see ___________. I also used the ipad to find out ___________. What I observed was _____________________ (2-3 sentences). Through these activities, I learned that the reason plant and animal cells are different is ______________. This shows me that _______________: I would like to learn more about this subject because __________________ . OR I still have a question about the topic we are studying. I am wondering ___________________________________.

Extra slides for information and study
Cell Theory
• All living things are made up of cells. • Cells are the smallest working units of all living
things. • All cells come from preexisting cells through
cell division.
Prokaryotic
• Do not have structures surrounded by membranes
• Few internal structures
• One-celled organisms, Bacteria
http://library.thinkquest.org/C004535/prokaryotic_cells.html
Eukaryotic• Contain organelles surrounded by membranes• Most living organisms
Plant Animal
http://library.thinkquest.org/C004535/eukaryotic_cells.html
Cell Membrane
• Outer membrane of cell that controls movement in and out of the cell
• Double layer
http://library.thinkquest.org/12413/structures.html
Cell Wall
• Most commonly found in plant cells & bacteria
• Supports & protects cells
http://library.thinkquest.org/12413/structures.html
Nucleus
• Directs cell activities• Separated from cytoplasm by nuclear
membrane• Contains genetic material - DNA
Nuclear Membrane
• Surrounds nucleus• Made of two layers• Openings allow material
to enter and leave nucleus
http://library.thinkquest.org/12413/structures.html
Chromosomes
• In nucleus• Made of DNA• Contain instructions for
traits & characteristics
http://library.thinkquest.org/12413/structures.html
Nucleolus
• Inside nucleus• Contains RNA to build
proteins
http://library.thinkquest.org/12413/structures.html
Endoplasmic Reticulum• Moves materials around in
cell• Smooth type: lacks
ribosomes• Rough type (pictured):
ribosomes embedded in surface
http://library.thinkquest.org/12413/structures.html
Ribosomes
• Each cell contains thousands
• Make proteins• Found on ribosomes &
floating throughout the cell
http://library.thinkquest.org/12413/structures.html
Mitochondria• Produces energy through
chemical reactions – breaking down fats & carbohydrates
• Controls level of water and other materials in cell
• Recycles and decomposes proteins, fats, and carbohydrates
http://library.thinkquest.org/12413/structures.html
Golgi Bodies
• Protein 'packaging plant'
• Move materials within the cell
• Move materials out of the cell
http://library.thinkquest.org/12413/structures.html
Lysosome• Digestive 'plant' for
proteins, fats, and carbohydrates
• Transports undigested material to cell membrane for removal
• Cell breaks down if lysosome explodes
http://library.thinkquest.org/12413/structures.html
Vacuoles
• Membrane-bound sacs for storage, digestion, and waste removal
• Contains water solution• Help plants maintain
shape
http://library.thinkquest.org/12413/structures.html
Chloroplast
• Usually found in plant cells
• Contains green chlorophyll
• Where photosynthesis takes place
http://library.thinkquest.org/12413/structures.html
Quick Review• Which organelle is the control center of the cell?
Nucleus• Which organelle holds the cell together?
Cell membrane• Which organelles are not found in animal cells?
Cell wall, central vacuole, chloroplasts• Which organelle helps plant cells make food?
Chloroplasts• What does E.R. stand for?
Endoplasmic reticulum
