Central Vacuole
In plant cells, rigidity is provided by a large membrane-bound sac called the central vacuole. This organelle regulates turgor pressure within the cell, helping to maintain cell structure and providing support to the plant. The central vacuole is filled with water, enzymes, and other substances, contributing to the cell's overall rigidity and shape.
This large, muscular sac is called the stomach.
A prokaryotic cell.
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
The part of a plant cell that is a sac of liquid is called a vacuole. Vacuoles are membrane-bound organelles that store various substances, including water, nutrients, and waste products. In many plant cells, a large central vacuole helps maintain turgor pressure, supporting the cell's structure. This contributes to the overall rigidity and stability of the plant.

The small sac located near the start of the large intestine is the appendix. It is a small, finger-shaped pouch that extends from the cecum, which is the beginning of the large intestine. The appendix is a vestigial organ with no known essential function in humans.
