Cork cells, unlike other plant cells, have a unique composition adapted for their protective role in the outer bark of woody plants. They are primarily composed of suberin, a waxy hydrophobic substance, which makes cork cells impermeable to water and gases. Additionally, cork cells lack a nucleus and other cellular organelles, such as chloroplasts, to maximize their ability to form a durable, waterproof barrier against environmental stresses.
