Vacuoles

Vacuoles. Melissa Smith. Vacuoles are a membrane-bound structures that play a role in intercellular digestion and release of wastes. The vacuoles are bound by a special membrane called tonoplast. These contain cell sap- which is dissolved substances and may also contain pigments.

  2. Vacuoles are a membrane-bound structures that play a role in intercellular digestion and release of wastes. • The vacuoles are bound by a special membrane called tonoplast. • These contain cell sap- which is dissolved substances and may also contain pigments. • The vacuole has no set shape or size, and the structure varies according to the needs of the cell. Vacuoles in General

  3. Two types of Vacuoles

  4. The animal cell does not need as much room to be taken up by a vacuole because the cells are already in an aqueous environment and can easily retrieve water. Vacuoles • Vacuoles mostly help perform larger roles by assisting in other jobs such as exocytosis which is the passage of materials from the cell. Vacuoles in Animal Cells

  5. Vacuoles can take up 30% to 80% of the plant cell. Vacuole • Vacuoles tend to be large in Plant Cells and tend to take up the majority of the cell. • When a plant is well watered, water collects in the vacuoles, but when a plant lacks water, the pressure in the vacuole is reduced and the plant wilts. Vacuoles in Plant Cells

  6. Animal Cell Plant Cell The importance, function, and appearance depends on the cell they are present in. Comparison of Cells
