If you've ever looked at a diagram of a plant cell, you probably noticed one organelle that stands out and is larger than all of the others. This organelle is known as the central vacuole. The central vacuole is a membrane-bound organelle containing water and other enzymes that function during the life of the plant.Structurally, the central vacuole is surrounded by a phospholipid bilayer. Phospholipids are molecules with a head and tail that form the majority of membranes in our body.f you've ever looked at a diagram of a plant cell, you probably noticed one organelle that stands out and is larger than all of the others.
