animal cells Flashcards
1
Q
what is an animal cell
A
- type of eukaryotic cell
2
Q
plasma membrane
A
- provides protection for cells
- regulates movement in and out of the cell
3
Q
cisternae
A
- network of membrane flattened sacs
- present in both smooth and rough endoplasmic reticulum
4
Q
smooth endoplasmic reticulum
A
- network of cisternae but NO ribosomes
- makes lipids and contains enzymes that detoxify
- storage site for calcium in skeletal muscle cells
5
Q
rough endoplasmic reticulum
A
- made up of cisternae
- protein synthesis takes place on the ribsomes which are then transported to the golgi body
6
Q
golgi body
A
- series of cisternae which collects and prcoesses proteins from the rough ER
- modifies them into vesicles to be transported to where they need to be
7
Q
mitochondrion
A
- rod like structure
- generates energy needed for chemical reactions and is the site of the final stages of cellular respiration
8
Q
nucleus
A
- largest organelle with a double membrane
- pores which let mRNA and ribosomes out, nutrients and hormones in
- contains chromosomes in chromatin form
9
Q
nucleolus
A
- dense spherical structure in the middle of the nucleus
- makes Rna and ribosomes.
10
Q
vesicle
A
- membrane bound sacs
- helps transport materials needed for survival
11
Q
lyosome
A
- spherical membrane bound structures containing hydrolytic enzymes
- destroys damaged organelles and cells
- enzymes kept seperate
12
Q
centriole
A
- small tubes of protein fibres, cylinder shape
- makes the spindle in cell division
