All cells have an outer covering called a membrane.• Agree (Plant cells have this between the cell wall and the inside)
• Phospholipid bilayer

The inside of a cell is like jello.•Agree
•This gel like substance is called cytoplasm.

Most human cells are about the same size as a bacterium.• Agree
![Page 5: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/5.jpg)
Some human cells can be as long as one meter long.• Agree
![Page 6: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/6.jpg)
Some cells can change shape.• Agree
![Page 7: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/7.jpg)
One way to group cells is by the presence or absence of a nucleus.• Agree
• Eukaryotic vs. Prokaryotic
![Page 8: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/8.jpg)
Most cells in your body have the same function. Only when they are grouped into tissues do they have different jobs.• Agree
![Page 9: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/9.jpg)
All cells have an outer covering made of cellulose, the same woody material that a tree has.• Disagree
• Only plant cells
![Page 10: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/10.jpg)
One of the main components of the cell membrane is fat.• Agree
• Phospholipids “lipid” means fat containing
![Page 11: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/11.jpg)
Many substances can move through the cell membrane to enter a cell.
•Agree
•A process called diffusion
![Page 12: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/12.jpg)
Cells have a skeleton.•Agree
•Cytoskeleton a series of intercellular proteins that help a cell with shape, support, and movement.
•A dynamic structure, parts of often which are destroyed, renewed or newly constructed.
![Page 13: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/13.jpg)
Organelles are “little organs”.•Agree
•Organelles carry out specific functions within the cell.
•Mitochondria Endoplasmic reticulum Ribosomes
•Lysosomes Vacuole Golgi Body
![Page 14: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/14.jpg)
Cells have a “director” like a boss, who tells everyone their job. This boss is the mitochondrion.
•Disagree
•Mitochondria are know as the “powerhouses” of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.
•The nucleus is the cell’s control center, directing all of the cell’s activities.
![Page 15: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/15.jpg)
All the instructions for the functions of a cell are found in the DNA.
•Agree
•The general term is chromatin, but DNA is in chromatin. We will study this more in cell reproduction, the next unit.
![Page 16: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/16.jpg)
There are really only three main differences between an animal and plant cell.
•Agree: Chloroplasts, Cell Wall and Vacuole (Plants cells have one that is large, animal cells have many)
![Page 17: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/17.jpg)
Chloroplasts in animals cells use sunlight, carbon dioxide and water to make food.
•Agree
•Photosynthesis
![Page 18: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/18.jpg)
Cells contain power plants, called mitochondria that release energy.
•Agreed
•Most of the cell’s energy is produced within these rod-shaped organelles.
![Page 19: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/19.jpg)
Cells have to get pre-made protein to build new cells from their food.
•Disagree
•Ribosomes are small structures function as factories to produce proteins. They may be attached to the endoplasmic reticulum, or they may float in the cytoplasm.
![Page 20: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/20.jpg)
Cells have a subway system to move materials from one part of the cell to another.
•Agree
•Golgi Body
![Page 21: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/21.jpg)
Cells have parts dedicated to manufacturing, transporting, packaging, storing, and recycling proteins and other materials.• Agree
![Page 22: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/22.jpg)
A cell can eat itself up from the inside out when it gets too old.
•Agree
•Lysosomes can recycle all matter by breaking it down in a useable form for the cell.
![Page 23: WHAT DO YOU THINK! - Pine Science](https://reader031.vdocument.in/reader031/viewer/2022012508/61849041d86b55215009fcfc/html5/thumbnails/23.jpg)
Cells combine to make tissues, tissues make organs, organs make systems and systems make an organism.
• Agree
