Cytokinesis in animal cells is accomplished by constriction of the cell along the plane of cell division (formation of a cleavage furrow).

Cytokinesis in animal cells is accomplished by constriction of the cell along the plane of cell division (formation of a cleavage furrow). In plant cells, which have cell walls, a completely different mechanism of cytokinesis has evolved.

Which of the following statements are true of cytokinesis in plant cells? Select the two that apply.

After chromosome separation is complete, a network of microfilaments forms near the plane of cell division that will separate the two new cells.
The cell plate consists of the plasma membrane and cell wall that will eventually separate the two daughter cells.
The plasma membrane of the parent cell grows inward, eventually joining with the cell plate.
Vesicles from the Golgi apparatus move along microtubules, coalesce at the plane of cell division, and form a cell plate.

Expert Solution

These two:

(not too sure about this one) The cell plate consists of the plasma membrane and cell wall that will separate the two daughter cells.

(100% sure about this one) Vesicles from the Golgi apparatus move along microtubules, coalesce at the cell division plane, and form a cell plate.

As the cell wall is developing, in plants, droplets or vesicles of pectin merge, forming a cell plate that eventually will become the middle lamella of the new cell wall.

In animal cells, the actin cytoskeleton forms a cleavage furrow to physically separate the cellular contents during cytokinesis. Explain why this approach won't work in plant cells, and describe how they do it instead.

The cell cycle represents the coordinated sequence of events in the life of a cell from its formation to its division into two daughter cells.

The cell cycle represents the coordinated sequence of events in the life of a cell from its formation to its division into two daughter cells. Most of the key events of the cell cycle are restricted to a specific time within the cycle. In this exercise, you will identify when various events occur during the cell cycle. Recall that interphase consists of the G1, S, and G2 subphases, and that the M phase consists of mitosis and cytokinesis. Drag each...

Cytokinesis (the splitting of cells after mitosis) differs in detail between different cell types. In simple terms, how does cytokinesis occur in plant cells, animal cells and yeast cells? Why would the process be different in these organisms?

The division of a bacterial cell into two daughter cells is accomplished by a protein called FtsZ. FtsZ is very similar to the tubulin subunits that form microtubules in eukaryotes.

The division of a bacterial cell into two daughter cells is accomplished by a protein called FtsZ. FtsZ is very similar to the tubulin subunits that form microtubules in eukaryotes. After the replicated bacterial chromosomes have moved to opposite ends of the cell, a ring of FtsZ proteins forms inside the plasma membrane in the region where the cell will divide. As the FtsZ ring constricts, the plasma membrane and bacterial cell wall fold in and eventually separate into two...
