Vacuoles

Vacuoles. Background. A vacuole is a membrane bound organelle. They are found in the cytoplasm of cells. Found in both plant and animal cells. A good example can be seen in most plant cells. Function. The vacuole performs intracellular secretion, excretion, storage, and digestion.

  1. Vacuoles

  2. Background • A vacuole is a membrane bound organelle. • They are found in the cytoplasm of cells. • Found in both plant and animal cells. • A good example can be seen in most plant cells.

  3. Function • The vacuole performs intracellular secretion, excretion, storage, and digestion. • The exact function of a specific vacuole is specialized depending on the function of the cell of which it is a part. • In plants vacuoles help maintain turgor pressure, which allows the plants to support structures such as leaves and flowers.

  4. Turgor Pressure In Plants

  5. General Structure • Vacuoles are enclosed within a cell. • They are surrounded with a membrane called a Tonoplast. • The Tonoplast contains channels for water that are used to help maintain the cell’s osmotic balance.

  6. Diseases • There are no known diseases involving the vacuole. • However, a loss of water within a plant will cause wilting due to the loss of turgor pressure.

  7. Questions What disease is associated with Vacuoles? • The common cold • The flu • Athlete's foot • None What is one role that a vacuole plays in a plant cell? • Turgor Pressure • Photosynthesis • Acorn Growth • The color of bark
