3A Eukaryotic Cells Flashcards
1
Q
plasma membrane (3)
A
- lipid bilayer with embeded proteins
- outer layer regulates what passes in and out of cell
- creates compartments and controls transportation
2
Q
Nucleus (3)
A
- surrounded by a double nuclear membrane and pores
- nucleus controls events in cytoplasm because chemical substances can pass through pores
- directs protein synthesis
3
Q
Nucleolus (4)
A
- area in nucleus with almost pure DNA and protein
- has a dense body
- produces ribosomes
- plays a part in the control of cell growth and division
4
Q
Smooth Endoplasmic Reticulum (2)
A
- does not have any ribosomes attached
- produces lipids and steroids
5
Q
Rough Endoplasmic Reticulum (4)
A
- interconnected, membrane-bound flattened sacs
- ribosomes attached to outer surface
- proteins are made on these ribosomes and then transported through the RER to other parts of cell
- involved in folding of proteins
6
Q
Golgi Apparatus (2)
A
- flattened sacs decreasing in size with vessicles attached
- modifies proteins and packages them in vessicles for transport
7
Q
Vesicle (2)
A
- single-membrane bound sac
- stores and transports substances
8
Q
Lysosome (3)
A
- single-membrane bound
- contains digestive enzymes
- digests damaged molecules
9
Q
Mitochondria (3)
A
- double-membrane bound
- inner membrane fold in to form cristae
- aerobic respiration
10
Q
80S ribosomes (3)
A
- protein and RNA complex with two subunits
- bigger and more complex than 70s
- protein synthesis
11
Q
Centrioles (3)
A
- one pair in each cell
- hollow cylinders made up of nine protein microtubules at a right angle
- produce spindles to move chromosomes
