Lesson Transcript
Instructor: Derrick Arrington

Derrick has taught biology and chemistry at both the high school and college level. He has a master's degree in science education.

Plant cells are composed of numerous organelles that work together in all aspects of the plant's life. In this lesson, you will learn about the central vacuole of plant cells.

?!!!What is the Central Vacuole in Plant Cells?

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. They align themselves in a certain manner and are able to selectively allow certain molecules to enter and exit the cells or organelles they surround. The size and shape of the central vacuole depends on the type of cell they are in and their specific function.
