Re: Do all components undergoing cyclosis move in the same direction and speed?

CYCLOSIS is the regular streaming movement of the cytoplasmic matrix 
around the vacuoles of the
cell. It is usually the pinosomes and phagosomes that move due to 
cyclosis. The organelles 
are held in their respective positions by the Endoplasmic Reticulum which 
forms a network in the
cell cytoplasm.

Coming to your question, think of the cell as your room. This is because a 
cell is a 3 dimensional
structure and trying to understand it with the help of a 2D concept is 
difficult. 
Now imagine that your room is criss-crossed by many roads from top to 
bottom (endoplasmic
reticulum) and the tables, chairs etc held in their respective positions 
(organelles). Now 
imagine that water is let in and is allowed to fill the entire room 
without any airspace (
cytoplasmic matrix). Put in some small items like toys and choclate 
wrappers. You will see that 
the toys and choclate wrappers move in the water in different directions 
and with different speeds
, thus producing different velocities. Similar can be thought about the 
cell. However, in a cell
many chemical reactions also takes place which enhances the movement of 
pinosomes, phagosomes and
other particles. Let's understand this with an example.

When a particulate matter enter the cytoplasm in a phagocytic vesicle, it 
is attracted towards the
lysosome. The lysosome contains hydrolytic (destructive) enzymes which 
digests the particulate
matter in the phagocyte.

Thus, we may conclude that the movement of components of cell has 
different speeds and directions.
