12.2 cytokinesis Flashcards
1
Q
cytokinesis in animals
A
cleavage
2
Q
cleavage furrow
A
shallow groove in cell surface
3
Q
how does the cell divide animals
A
contractile ring of actin filaments and microfilaments of protein myosin
-actin and myosin interact and cause the ring to contract, dividing the cell by pinching it into 2
4
Q
cytokinesis in plant cells
A
cell plate
5
Q
how does the cell divide in plants
A
in telophase, vesicle from the Golgi apparatus move along microtubules to the middle of the cell where they
coalesce (form one big mass)
- which becomes the cell plate
- more material is brought by more vesicles until plasma membrane fuses around the new cell
