Answer 2

Answer:

Vacuoles are cytoplasmic membrane-bound cell organelles that are brimming with a variety of chemicals in a watery fluid.

Explanation:

1. Structural features-

• A membrane-bound structure called a vacuole is located in the cytoplasmic matrix of a cell.
• Tonoplast refers to the membrane that encloses the vacuole.
• The vacuole's constituents, referred to as the cell sap, are distinct from the cytoplasm around it.
• Phospholipids are the main component of the membranes.

2. Main functions-

• Salts, minerals, colors, and proteins are kept in a vacuole within the cell. The cell sap is the liquid that fills a vacuole.
• The water-filled vacuoles push against the cell wall with force. Turgor pressure is the term for this. It gives the cell structure and makes it more resilient to harsh environments.
