Describe the process of osmoregulation in the amoeba?
First i will like to introduce you to Osmoregulation
Osmoregulation is the ability of an organism to maintain a constant osmotic
pressure within the blood and tissue fluid.
Different chemical activities in the body produce many by-products several of
which are wastes. These waste products if allowed to accumulate will turn out
to be toxic and affect the physiological activities of the body cells. These wastes
have to be expelled out or it may eventually result in the death of the
Excretion is performed by the contractile vacuole.The content within the tissues
of amoeba is hypotonic due to the salt concentration. so water turns to enter
the cells rapidly than it is needed. The excess water if not expelled will
eventually burst the cells.
some of this excess water then diffuse into the contractile vacoule gradually
and gradually until the vacuole becames turgid. The water is then expelled by
diffusion out of the cells.
The mode of nutrition in amoeba is holozoic. The process of obtaining food is called phagocytosis. Amoeba feeds on microscopic organisms floating on water. The nutrition involves processes like ingestion, digestion, assimilation and egestion. Process : Amoeba forms pseudopodia to take food. When the tips of
organisms need the process of homeostasis i-e the changes in the internal environment within a narrow range as a response to wide range changes in the external environment.this is done by osmoregulation,thermoregulation,etc. organisms need the process of homeostasis i-e the changes in the internal environment within a narrow range as a response to wide range changes in the external environment.this is done by osmoregulation,thermoregulation,etc.
