Cell Structures Flashcards
(30 cards)
What is the size of a cell surface membrane ?
What is its function?
7 nm thick.
Partially permeable membrane, controls what comes in and out of the cell.
What is the size of a nucleus ?
5 micro meters
Boundary membrane if nucleus?
Double bound membrane organelle.
What is the function of the nucleus?
It controls cell activity as it has DNA.
What does the nucleolus do?
Produces
ribosomes
What does the endoplasmic reticulum?
Can bud off vesicles from Golgi body
Does the endoplasmic reticulum have a boundary membrane organelle??
Yes, a single one
What does the rough endoplasmic reticulum do?
Transports newly synthesized molecule around the cell
Function of ribosomes?
Protein synthesis
What does the Golgi body do?
Sorts, processes, and modifies proteins.
Produces lysosomes
Converts sugars to cell wall components
What is the boundary organelle of the Golgi body?
It is single
What is the size of lysosomes ?
0.1 to 0.5 nm
What is there boundary organelle of lysosomes?
Single
What is is the function of a lysosome?
To digest worn and unwanted bacteria
Size of mitochondria ?
1 micro meter in diameter
2-8 micro meter in length
Boundary organelle of mitochondria?
Double bound membrane organelle
WHAT is the function of mitochondria?
Produce ATP in plant cells and animal cells.
WHAT is the size of micro tubules
25 nm
Small
Hollow tubes
WHAT is the function of micro tubules
Provide mechanical strength, shape and ability to move
Involved in cell division
Boundary membrane organelle? (Microtubules)
None
WHAT is the size of centrioles?
2hollow Tunes
500 nm
Placed at right angles
Each are composed of 9 triplet micro tubules
Boundary organelle? (Centrioles!
None
Function of centrioles?
Can act as the staring point for the growth of spindle micro tubules during cell division
Size of chloroplasts,
3 - 10 micro meters
