| Cell Theory | ||
| #1 | The cell theory was only stated after the __________ was improved by Robert _______. | Microscope, Hooke |
| #2 | Part of the cell theory states that all living organisms are made up of _______. | Cells |
| #3 | The cell theory states that all cells come from _________ cells. | existing |
| #4 | The cell theory was stated by ________ & _________ who worked together and ____________ who saw cells divide. | Schwann, Schleiden, Virchow |
| #5 | The cell theroy states that the cell is the ______________ basic ______ of life. | smallest, unit |
| Prokaryote, Eukaryote or Both | ||
| #1 | the DNA is in the cytoplasm |
Prokaryote |
| #2 | Has cytoplasm |
Both |
| #3 | Has a CELL membrane |
Both |
| #4 | Organelles are membrane-bound |
Eukaryote |
| #5 | Different types of cells perform different types of jobs |

| Cell Strucutres and Functions | ||
| #1 |
|
It is a Mitochondria and its function is to create ATP through the breakdown of sugars. |
| #2 | In a plant cell, what is the large, clear, sac-like structure called and what is its function?
|
The large central vacuole and its main function is to store water and it gives the plant support. |
| #3 | In a plant cell what are the organelles that holds chlorophyll, which makes the plant green?
|
Chloroplasts and they conduct photosynthesis and make sugars by using carbon dioxide, water and sunlight, creating food for the cell. |
| #4 | This image shows all 4 cell organelles that facilitate the creation, packaging and transproting of proteins. State the four organelles and thier role in the production of protein.
|
The Nucleus holds the DNA that tells the Ribosomes to create proteins by making long chains of amino acids. These proteins are then sent and packaged on the Endoplasmic Reticulum through thier folded membranes to the Gogli Complex. At the Golgi Complex, they are modified to perfomr different jobs and either sent to other parts of the cell or out of the cell.
|
| #5 | Where is the DNA located?
|
The nucleus has a center called the nucleolus where the DNA is stored.
|
| Plants Versus Animals | ||
| #1 | What organelle do Animals have that Plants do not and what do they do? |
Lysosomes and they remove waste from the cell. |
| #2 | What 3 parts do plant cells have that animal cells do not? |
A cell wall; outer rigid wall
chloroplasts; conduct photosynthesis
large central vacuole; stores water |
| #3 | Why does an animal cell NOT have a cell WALL surrounding the cell membrane? |
Animals have bones structures so their cells do not need the extra support. |
| #4 | Which one has cytoplasm? |
ALL cells have cytoplasm, so both of they do. |
| #5 | Why doesn't an animal cell have a large central vacuole? |
Animals are mobile and can get to their water resource while plants cannot move from where they are planted and must rely of rainfall.
Animals also have bone strucutre and do not need extra support to stay upright. |
| Homeostasis; Passive and Active Transport | ||
| #1 | Describe how diffusion was demonstrated during our lab activity.
|
The high concentration of food coloring was in the drop of food coloring. After it was placed int he water, it moved throughout all of the water, eventually evenly distributed throughout the whole beaker. |
| #2 | How is a raft floating down a river like a particle/molecule going through passive transport?
|
It is like a raft floating down a river because the raft is being pushed by the current and does not require any added or extra energy in order to go on its path.
|
| #3 | How is a person canoeing upriver like a molecule/particle going through active transport?
|
A particle that is going through Active Transport is going against the gradient or current because it is moving from an area of low concentratio to an area of high concentration. The gradient or curent want to puch it backwards so the molecule needs extra energy (oars pushing the water) to get across the membrane.
|
| #4 | What is this process called and what is happeneing?
|
This is exocytosis. The cell is removing waste from the cell by wrapping the large partice in a vesicle. The vesicle adheres to the cell membrane and the cell membrane opens up and the particle leave the cell.
|
| #5 | What is this process called and what is happeneing?
|
This is endocytosis,a type of active transport and the cell is bringing in a large particle into the cell. The cell memebrane wraps around the particle and brings it in by forming a vescilce around the particle.
|
| Final Question | |
List the 3 things that cells must do to maintain homeostasis (keeping the internal environment the same)? |
Cells must: 1. Create new cells 2. Exchange materials and remove waste 3. Obtain or use energy |
