Cycles (Gr. Kyklos - Circle)

Cycling is a circular movement of cytoplasm commonly seen in plant leaf cells.

Circular movements of the cytoplasm play an important role in the transport of nutrients and other components within the cell. They help distribute organelles, nutrients and various compounds evenly in the cytoplasm.

Cyclic movement occurs due to the actin filaments of the cytoskeleton, which contract and cause the cytoplasm to move in a circle around the central vacuole. The speed of cyclic movement can reach several microns per second.

Cyclic movements are especially active in young, fast-growing cells. In mature cells, the intensity of cyclosis, as a rule, decreases.

Thus, cyclic movements of the cytoplasm play an important role in the life of the plant cell, ensuring an even distribution of nutrients and organelles.
