Then the endoplasm in the area surrounding the vacuole contracts and the fluid contents which contain traces of urea and carbon dioxide are discharged out into the surrounding pond water. Thus the contractile vacuole functions effectively as an organelle that performs both excretion and osmoregualtion.

EXCRETION IN AMOEBA. Amoeba is a unicellular organism found in fresh water. In amoeba carbon dioxide and ammonia are the main waster materials. These waste materials are excreted out by the process of diffusion through general body surface. In amoeba, contractile vacuoles also play some role in the removal of waste materials. The waste materials present in the cytoplasm of amoeba enters the contractile vacuole.

1 Its cell membrane is semi permeable and the exchange of gases (O2 and CO2) takes place by diffusion through body surface in water.

Besides the cell membrane, Amoeba has a simple device known as the contractile vacuole which is an organelle 30 - 50 m in diameter. This small sac lies freely in the cytoplasm of the organism.

The CV (Contractile Vacuole) is an organelle that can be found in amoebae, protist, and in unicellular protoctists. For less confusion the CV is not like a vacuole we studied with animal or plant cells. It has different functions. The Amoeba's CV's function is to transport water in and out of the cell membrane to regulate the amount of water in the Amoeba's cytoplasm.

0. excretion takes place generally by contractile vacuole this is because they do not have a complex body structure and are single celled so there is no specific organ for excretion... i think it will help you. Posted by Muskaan Jain (student) on 15/8/13.

Amoeba's CV fills with water then contracts and release water by exocytosis. Even though the amoeba can release water with no energy required, amoeba requires ATP to take in water. This cycle continues.

EXPERT ANSWER. 1  Contractile vacuole in amoeba performs excretion and osmoregulation. 2  Its cell membrane is semi permeable and the exchange of gases (O2 and CO2) takes place by diffusion through body surface in water.

Excretion and Osmoregulation in Amoeba. Amoeba is a protozoan which forms the simplest of all groups in the animal kingdom. Inspite of being unicellular it is physiologically balanced and performs all the essential processes of an animal. Carbon dioxide, urea, uric acid and mineral salts are not allowed to collect beyond a certain limit in the organism.

what do amoeba excrete in contractile vacuole
Its cell membrane is semi permeable and the exchange of gases (O2 and CO2) takes place by diffusion through body surface in water. The Amoeba excrete is semi permeable and the exchange of gases like Oxygen and Carbohydrates takes place by diffusion through body surface in water.
