WebUltrastructural data on the protozoan Amoeba proteus support a model of membrane recycling. At systole the amoeba contractile vacuole fuses with the cell surface and expels its contents. Observations by electron microscopy indicate that, as the vacuole empties, its bounding membrane transforms into tiny (35 nanometers in diameter) vesicles, identical … WebEndoplasm contains a number of organelles or structures suspended in it. These organelles are nucleus, contractile vacuole, food vacuoles and water globules. Nucleus: In Amoeba proteus, there is a single conspicuous nucleus. The nucleus appears as a biconcave disc in young specimens but it is often folded and convoluted in older specimens.

Contractile vacuole helps with waste excretion. Its function is to act as the cell’s pump for removing extra water and waste. The extra water is gathered in the vacuoles when it enters the cytoplasm of the cell. cryptsetup error

Contractile vacuole in protozoa Amoeba is meant for - Vedantu

WebAns: Amoeba requires contractile vacuoles for osmoregulation, which prevents the cell from retaining excess water. If the cell absorbs too much water, it can result into cell rupture. … WebExpert Answer. •Contarctile Vacuole ( also called pulsating vacoule) is a specalized structure present in single- celled organisms (mainly in Pro …. View the full answer. Transcribed image text: 6. What is a contractile vacuole? WebThe contractile vacuole is a part of the cell that helps to regulate the amount of water that is inside a cell. It works as a protective mechanism to prevent the cell from taking in too much water. It also helps to regulate the pressure within the cell. Cells are surprisingly complex systems. and it’s easy to be confused and unsure of the ... dutch ministry of defense
