Cell Division Flashcards
Cell division occurs in animals by a process called what?
Cleavage
What appears around the cell during cell division in animal cells?
A cleavage furrow
Where does the cleavage furrow form during cell division of animal cells?
It appears around the cell and lines up with the position occupied by the equator during metaphase
How is a cleavage furrow responsible for the splitting of two animal cells?
The cleavage furrow which forms around the cell becomes deeper until it eventually divides the cytoplasm and splits the cell
What prevents a cleavage furrow from forming in plant cells?
The rigid cell wall
What forms instead of a cleavage furrow in plant cells?
A small number of membrane-enclosed sacs called vesicles form and gather in the area between the two nuclei
What do vesicles formed during plant cell division contain?
Cellulose which is used to form new cell walls during cell division
What do vesicles form during plant cell division?
The cell plate
How does the cell plate formed by vesicles contribute to plant cell division?
2 points
The cell plate enlarges and its membranes join with the cell membrane of the original cell
The cell plate then forms two cell walls, one for each of the daughter cells
What is the middle lamella?
The region between two adjacent plant cell walls
What is the region between two adjacent plant cell walls called?
Middle lamella
