Bell Ringer – 10/3 - pg. 173

Cells fall into two broad categories, depending on whether they contain a __(1)__. The nucleus controls many of the cell’s __(2)__. __(3)__ are cells that contain nuclei. __(4)__ are cells that do not contain __(5)__.

Cells come in a great variety of shapes and amazing range of __(1)__. Although typical cells range from 5 to __(2)__ micrometers in diameter, the tiniest mycroplasma bacteria are only 0.2 micrometers across. The giant __(3)__ Chaos Chaos may be 1000 micrometers in diameter, large enough to be seen with the __(4 – two words)__. All cells have two characteristics in common. They are all surrounded by a barrier called a __(5 – two words)__ and they contain __(6)__.

The Cell Theory States:

• All __(1)__ things are composed of __(2)__.

• Cells are the basic units of __(3)__ and __(4)__ in living things.

• __(5)__ cells are produced from __(6)__.

Identify the following as prokaryotic or eukaryotic characteristics by answering with a “pro” or a “eu”:

• Larger and complex cells.

• Example is bacteria.

• Genetic material is in cytoplasm.

• Example is complex organisms such as a human.

• Larger in size.

• Has organelles that do a job.

• Smaller in size.

• Less complicated.

All bags on the floor please!!!

In the same way that the main office controls a large factory, the __(1)__ is the control center of the cell. The nucleus contains nearly all of the cell’s __(2)__ and with it the coded instructions for making __(3)__ and other important molecules. Most nuclei also contain a small, dense region known as the __(4)__. The nucleolus is where the assembly of the __(5) __ begins.

Bell Work – 10/11 & 10/13 – pg. 177

One of the most important jobs carried out in the cellular “factory” is making __(1)__. __(2)__ are assembled on __(3)__. Ribosomes of small particles of RNA and protein found throughout the __(4)__. The produce __(5)__ by following coded instructions that come form the __(6)__.

Eukaryotic cells also contain an internal membrane system known as the __(1)__ or __(2)__. It is the site where lipids and __(3)__ are assembled and exported from the cell. Rough ER is given this name because of the __(4)__ found on its surface. The other portion of the ER is known as __(5)__ because ribosomes are not found on its __(6)__.

Even the neatest, cleanest factory needs a __(1)__, and that’s what lysosomes are. Lysosomes are small organelles filled with __(2)__. One function of lysosomes is the __(3)__, of lipids, carbohydrates, and __(4)__ into small molecules that can be used by __(5-finish the sentence)__.

Bell Work – 10/18 - pg. 179

Every factory needs a place to store things, and cells contain places for __(1)__ as well. Some kinds of cells contain saclike structure called __(2)__ that store materials such as __(3-four words)__. In many plant cells there is a single, large central vacuole filled with __(4)__. Vacuoles are also found in some __(5)__ and some __(6)__ cells.

• Name the function of the following (wouldn’t hurt to use your notes):

1) Endoplasmic reticulum

2) Lysosomes

3) Mitochondria

4) Vacuole

Bell Work – 10/21 - NOTES

• Name the following organelles from the function below:

• Holds water and other materials.

• Contains the green pigment chlorophyll.

• Sorts, modifies, and packages both proteins and lipids.

• Converts the food you eat into energy the cell can use.

• Determines what enters and leaves the cell.

Name the following organelles from the function below:

• Breaks down food and useless organelles.

• Site of protein synthesis.

• Site where proteins and lipids are produced and exported from the cell.

• Gives the cell structure and shape.

• Is everything in the cell except the nucleus.

Bell Work – 10/20 - NOTES

• What three organelles are associated with plant cells?

• Which organelle contains the cells DNA?

• Where are proteins created?

• Which organelle has strong digestive enzymes in order to digest foreign material in the cell?
