What is the difference between plant and animal cells? |
|
Definition
Plant cells are larger than animal cells. Plant cells have chloroplasts unlike animal cells. Plant cells have a cell wall unlike animal cells. Vacuoles are more obvious in plant cells than animal cells i.e. large central vacuole in plant cells.

Term
What role does the nucleus play in the cell? |
|
Definition
The nucleus is the cell infomation center. It contains chromosomes wich carry DNA. |

Term
What role does the vacuole play in a cell? |
|
Definition
A vacuole is the one large water filled sack in a plant cell. small vacuoles can be found in animal cells. |

Term
| What role does the cell wall play in a plant cell? |
|
Definition
The cell wall is the outer boundry of a plant cell. It protects the things on the inside of the cell. |

Term
| What role does a cell membrance play in a cell? |
|
Definition
| A cell membrance is the outer boundry of an animal cell and the inner boundy of the plant cells. This controls what substances enter and exit the cell. |

Term
What role does the mitochondria play in a cell? |
|
Definition
Mitochondria is the power house of the cell where ATP energy is produced(cells requiring more energy will have more mitochondria). |
|
|
Term
| What role does the chloroplasts play in a plant cell? |
|
Definition
Chloroplasts is where the photosynthesis happens. These give the plant its green pigmentation. |

Term
| How do you calculate the magnification when using a microscope? |
|
Definition
The total magnification is the magnification of the objective (10x/40x/100x usually, but can be something else) which is further magnified by the eye piece (typically 10x, but others exist). |

Term
What are cells, tissues and organs? |
|
Definition
Cells make up tissues. Tissues make up organs, and organs make up body systems. The only difference is the level of complexity. |

Term
What is cell respiration? |
|
Definition
Cellular Respiration, process in which cells
produce the energy they need to survive. it includes the beaking down of food with the use of oxegyn |
|
|
Term
What is cellular respiration? |
|
Definition
The formula for aerobic cellular respiration is
C6H12O6 + O2 → CO2 + H2O + Energy (as ATP)
The word equation for this is:
Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP) |
|

Term
What is osmosis and diffusion? |
|
Definition
Diffusion is the movement of molecules from an area ofHigh concentration to an area of low concentration. Basically the molecules go from where they are plenty of them to where there are little. Osmosis is basically the same thing as diffusion but it deals solely with water.The movement of water molecules from where they are in high concentration to where they are in low concentration. |
