6) Diffusion is the movement of molecules for higher concentration to lower concentration whereas in OSMOSIS is the movement of Water molecules from lower concentration to higher concentration across a SEMI PERMIABLE membrane... hope this helps u out
archii25:
Plasmolysis is when a living plant loses water through osmosis, there is shrinkage or contraction of the protoplasm away from the cell wall. This phenomenon is called PLASMOLYSIS. The plants posses a rigid cell wall and therefore when the cell loses water the plasma membrane shrinks and moves away from the cell wall.
Semiautonomous organelles are those organelles which have their own DNA and RNA and can SELF REPLICATE. For example MITOCHONDRIA AND CHLOROPLAST
An amoeba obtains its food with the help of its false legs.that is called Pseudopodia. They surround the food particle and then engulp it
