What is a cell membrane?
|
double layer of phospholipids that encloses cell
|
|
|
Where is a cell membrane found?
|
both animal/plant

|
|
What is a cell wall?
|
protective layer external to plasma membrane in plant cells, bacteria, fungi, and some protists; protects cell and helps maintain its shape
|
|
|
Where is a cell wall found?

|
What is cytoplasm?
|
This jelly-like substance, composed mostly of water, seperates the nucleus from the cell membrane, and is where all other cell organelles are found. It is filled with protein fibers called microtubules that make up the cytoskeleton which aids in the cell's movement and gives the cell its shape.

|
|
What is the nucleus?
|
An organelle that is enclose din a double membrane, contains DNA, and communicates with the surrounding cytosol via numerous nuclear pores.
|
|
|
Where is the nucleus found?

|
What is the nuclear membrane?
|
The nuclear membrane is the double membrane that surrounds the nucleus within a cell. Its outer part is continuous with the endoplasmic reticulum.

What is the nucleolus?
|
produces ribosomes, which move out of nucleus and take positions on the rough endoplasmic reticulum where they are critical in protein synthesis

What is the smooth endoplasmic reticulum?
|
a network of membrane bound vesicles and tubules that appears smooth and functions in lipid/steroid hormone synthesis and break down of lipid soluble toxins in liver cells

|
What is the Golgi Apparatus?
|
A stack of membranes that collects and modifies chemical compounds, packaging and distributing the molecules that are produced in one part of the cell but used by another part, or those to be exported to the outside of the cell.
