Amoebas move through amoeboid movement, forming temporary finger-like projections called pseudopodia through the forward flowing of cytoplasm. This theory of pseudopodia formation was first proposed by Hymen in 1917 and later supported by Pantin and Mast, and is now widely accepted. The theory describes how attachment of the amoeba to a surface leads to the conversion of plasmagel to plasma sol at the point of pseudopodium formation, with the constant flow of plasma sol causing growth of the pseudopodium until it converts back to plasmagel upon striking the hyaline cap.

2. Amoeba shows
characteristics
amoeboid movement
by the formation
of finger-like
temporary process,
the pseudopodia.
These are formed
as a result of
flowing forward of cytoplasm.

3. This theory first put
by Hymen(1917)And later
supported by Pantin(1923-26) and Mast,
Widely acceptable view, now a days.

4. The theory describe bellow:-

5. Attachment of Amoeba
to the substratum.
At the point of formation
of pseudopodium,
the plasmagel converts into
plasma sol begins to flow.
The constant flow of plasma sol
result in the growth of
pseudopodium.

6. When plasma sol strikes the hyaline cap,
it converts into plasmagel,
which is called gelation.
At the opposite end, the plasma gel converts
into plasma sol converts into
plasma sol to continue the supply of
plasma sol. It called as solation.
