|
Compare the functions of the cell wall and the cell membrane.
|
--The cell membrane separates a cell from its environment and controls what substances go into and come out of the cell.
--The cell wall protests and supports the cell. |
|
|
What are the characteristics of cellulose?
|
Strong
|
|
|
How does cellulose help with one function of the cell wall?
|
Because cellulose is strong, the cell wall, which is made up of cellulose, can protect the cell and provide support.
|
|
|
Identify the functions of ribosomes and Golgi bodies.
|
The ribosomes produce proteins. The Golgi bodies distribute these proteins and other materials to different parts of the cell.
|
|
|
Describe the characateristics of endoplasmic reticulum.
|
The endoplasmic reticulum has many passageways that carry proteins and other material from one part of the cell to another.
|
|
|
How are the functions of ribosomes, Golgi bodies and the endoplasmic reticulum related to one another?
|
The ribosomes make proteins. The endoplasmic reticulum carries the proteins to the Golgi bodies, which distribute them to other parts of the cell.
|
|
|
What is a tissue?
|
A tissue is a group of similar cells that work together to perform a specific function.
|
|
|
What is an organ?
|
An organ is a body structure made up of different kinds of tissues that function together.
|
|
|
What is the relationshop among cells, tissues, and organs?
|
Cells make up tissues, which make up organs.
|
|
|
Would a tissue or an organ have major kinds of specialized cells? Explain.
|
An organ would have more kinds of specialized cells because it is made up of different tissues, each of which consists of the same type of cells.
|
|
|
Where is the genetic material in a bacterial cell?
|
In the cytoplasm.
|
|
|
Constrasts the location of genetic material in bacterial cells to its location in plant and animal cells.
|
A plant or animal cell's nucleus encloses chromatin that contains the cell's genetic material. A bacterial cell's genetic material is found in the cytoplasm.
|
|
|
What shape do the cell walls give to the onion root cells?
|
rectangular
|
|
|
Look at the two pictures. What is the difference between the onion root cells and the paramecium?
|
--The onion root cells have both a cell wall and a cell membrane.
--The single-celled paramecium has only a cell membrane. |
|
|
What is the function of the cell membrane?
|
It controls what substances come into and out of a cell.
|
|
|
Bacterial Cells
What is a bacterial cell? |
Bacterial cells are very different from a plant and animal cells.
--Bacterial cells are usually much smaller than plant or animal cells. --Human cells are 10 times as large average bacterial cell. --Bacterial cell have a cell wall and a cell membrane. --Bacterial cell does not have a nucleus. --The bacterial cell's genetic material, which looks like thick, tangled string, is found in the cytoplasm. --Bacterial cells contain ribosomes, but none of the other organelles found in plant or animal cells. |
