Here's why:
* Large Central Vacuole: Plant cells typically have a large, central vacuole that occupies most of the cell's volume.
* Fluid-Filled Sac: This vacuole is a fluid-filled sac surrounded by a membrane called the tonoplast.
* Functions: The vacuole plays a crucial role in:
* Storage: It stores water, nutrients, pigments, and waste products.
* Turgor Pressure: The water inside the vacuole exerts pressure on the cell wall, maintaining the cell's shape and rigidity.
* Growth: The vacuole plays a role in cell expansion.
While the vacuole is often the most prominent structure in the center, other organelles like the nucleus, endoplasmic reticulum, and Golgi apparatus are also present in the cytoplasm surrounding the vacuole.
