Scientists separate cells into 2 major categories: |
|
Definition
the eukaryotic cell and the prokaryotic cell. |
|
|
Term
What are prokaryotic cells? |
|
Definition
Most prokaryotic cells are unicellular (single-celled organisms like bacteria). |
|
|
Term
What are eukaryotic cells? |
|
Definition
Most eukaryotic cells are multicellular (many-celled organisms like plant and animal cells). |
|
|
Term
|
Definition
Both animal and plant cells are surrounded by a protective covering that encloses the entire cell called the cell membrane. The cell membrane is semi-permeable which means that it will allow certain materials into the cell and will keep other materials out (kind of like the fence surrounding the factory). |
|

Term
|
Definition
Contained inside the cell membrane is a jelly-like substance called cytoplasm which holds all the other parts of the cell. |

|
Definition
The nucleus is the central command center that contains the genetic information for the cell (kind of like the boss in the factory). |

|
Definition
Ribosomes are parts of the cell that produce proteins (kind of like the workers in the factory). |
|
|
Term
|
Definition
Moves the proteins (produced by the ribosomes) to the Golgi apparatus (kind of like the conveyer belt tht moves the product to the packaging department). |
|
|
Term
|
Definition
Packaging department for the proteins produced by the ribosomes (kind of like the packaging department that gets the product (protein) ready to be shipped out). |
|
|
Term
|
Definition
The vesicles transport these proteins to other parts of the cell (kind of like the delivery truck in a factory). |
|
|
Term
|
Definition
The lysosomes act as the cleanup crew (in an animal cell) because they digest old, worn out parts of the cell (kind of like the janitor of the factory). |
|
|
Term
|
Definition
Produces energy (kind of like the generator of the factory). |
|
|
Term
|
Definition
The chloroplasts use energy from the sun to make food (sugar) for the plant in the process called photosynthesis (kind of like the solar energy source for the factory...uses the sun). |
|
|
Term
|
Definition
The central vacuole holds water, waste and other materials for the plant and acts like a huge storage tank (kind of like the storage tank in the factory). |
|
|
Term
|
Definition
Contained inside the cell membrane is a jelly-like substance called cytoplasm which holds all the other parts of the cell (kind of like the air in the factory that surrounds everything else). |
|
|
Term
|
Definition
The cell wall is a tough, outer covering that lies just outside the cell membrane and gives the plant extra support (kind of like an exta security fence around the factory). |
|
|
Term
|
Definition
It is produced by the ribosomes (kind of like the product produced in the factory). |
|
|
Term
Which 3 parts are found in plant cells only? |
|
Definition
Cell Wall, Chloroplasts, and Central Vacuole |
