nucleus
What would happen if a cell lost its nucleus?
The cell would die almost instantly.
What is the purpose of the membrane.
Is found in all cells and separates the interior of the cell from the outside environment.
What is the definition of the mitochondria?
A powerhouse of the cell creates most of the energy.
Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm.
Can you live without ER?
Without the endoplasmic reticulum, the cell will not survive.
Can a cell survive without a nucleus?
No, a cell cannot survive without a nucleus.
What is a membrane?
A thin layer that forms the outer boundary of a living cell or of an internal cell compartment.
Are mitochondria in only animal cells?
No, they are in both animal and plant cells.
Where are ribosomes found?
Ribosomes are found free in the cytoplasm or on the surface of the rough endoplasmic reticulum.
Does ER have DNA in it or not?
Endoplasmic reticulum does not contain any DNA
What makes a nucleus?
A collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral.
Why is the membrane important?
The cell membrane provides an important barrier that protects the cell's interior.
Do fungi have mitochondria?
Yes, they usually have mitochondria.
How are Ribosomes important for life?
All cells need ribosomes to make the proteins necessary for life.
Does the ER have ribosomes on it?
The rough ER, which is covered by ribosomes on its outer surface
What does the nucleus do easily?
Controls and regulates the activities of the cell.
Where is the membrane located?
On the outer surfaces of the cells and are responsible for the regulation of what enters or exits the cells.
Do insects have mitochondria?
Yes, they are packed with them.
Are ribosomes in all cells?
Ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria.
What is the function of the ER?
In general, its function is to produce proteins for the rest of the cell to function.
What are the three main things in a nucleus?
What happens if the cell membrane is damaged?
The cell will die because if the membrane is damaged it cant protect the cell.
How many mitochondria does a cell have?
1,000 to 2,500
Where are ribosomes not found?
They are not present in vacuoles.
Where is the ER located in a cell?
Typically next to the nucleus.
