| Question | Answer |
|---|---|
| Matthias Schleiden | a German Scientist, used one of the new microscopes to look at plant cells. |
| Theodor Schwann | used a microscope to study animal cells. |
| Robert Hooke | an English Scientist, built a microscope. He used the microscope to look at cork, which is part of a cork oak tree’s bark. What he saw looked like the opening of a honeycomb. He compared it to the small rooms, called cells in the monastery. |
| Cell Theory : | All living things are made up of one or more cells. The cell is the smallest unit of life. All new cells come from pre-existing cells. |
| Macromolecules | these substances called macromolecules form by joining many small molecules together |
| Nucleic acid | are the macromolecu;es that form when long chains of molecules called nucleotides join together |
| Proteins | long chains of amino acids molecules. |
| Lipids | a large macromolecule that DOES NOT dissolve in water. |
| Carbohydrates | one sugar molecule, two sugar molecules or a long chain or sugar molecules make up carbohydrates. |
| The _______ states the cell is the basic unit of all living things? | Cell theory |
| Distinguish between carbohydrates and lipids? | Carbs are sugars that store energy AND provide structural support, communicate between cells. Lipids are fats which are not soluble in water AND protect cells. |
| Use the term nucleic acid in a sentence? (DO NOT DEFINE) | DNA and RNA are nucleic acids. |
| Which macromolecule is made from amino acid? | Proteins |
| Describe how the invention of the microscope helped scientists understand cells? | The invention of the microscope enables scientists to see the structure of the cell and its functions. |
| Compare the function of DNA and proteins? | DNA stores genetic information, whereas proteins are used for many functions, such as communicating between cells, transport material, structural support, and breaking down of the nutrients. |
| How are we able to see cells? | Light microscopes allow us to see cells. With the help of slides to make thin layers of cells and hold them in place, we can zoom in up to 1,000 times the size of the specimen on a slide. |
| What are some of the different parts of a cell? List the parts. | Cells have many parts, called organelles. Some examples of organelles include the nucleus, the cytoplasm, the cell membrane, the vacuole, the lysosome, and the mitochondria. Each organelle has a specific function to help keep the cell alive. |
| How are animal cells and plant cells different? | Animal and plant cells have many of the same organelles with a few exceptions. Plant cells have a cell wall to help give the plant structure. Plant cells also contain chloroplasts; the organelles where photosynthesis takes place. |
