How does a plant cell accomplish cytokinesis
pychu [463]

Answer:Cytokinesis in plant cells involves plants using spindle structures called phragmoplasts to carry vesicles of the cell wall material such as cellulose to the new cell plate. ... After the plate divides the plant cells into two daughter cells, the plasma membrane seals off and fully separates the two new cells. During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

Which structure of the heart is responsible for prevening blood from flowing in tthe wrong direction?
Sloan [31]
The valves are responsible for preventing blood from flowing in the wrong direction, they are present in the veins, and the arteries don't need them because the aorta (biggest artery) pumps or in other words pushes it with such a force that no other force can change its direction, in the veins there is no structure present for pumping them as a result we have got valves so that they go in one direction...... the meaning of the word valve is to allow in one direction
