suberin
Definition
Noun (mass noun) - A waxy, hydrophobic substance: Suberin is a complex biopolymer found in the cell walls of cork (the bark of the cork oak) and other plants. It acts as a barrier, preventing water loss and protecting the plant from pathogens and physical damage.
Usage Examples
- (The natural waxy substance in cork prevents liquid and air from passing through.)
- (The polymer helps control the movement of water into the plant.)
Advanced Usage
"suberin deposition": The process by which suberin is laid down in plant cell walls.
- After injury, the plant accelerates suberin deposition to seal the wound. (The plant produces more suberin to create a protective layer over damaged tissue.)
"suberin lamellae": Thin layers of suberin found in plant cell walls.
- The suberin lamellae in the root endodermis are crucial for selective nutrient uptake. (The layered suberin structures help filter what enters the plant's vascular system.)
Variants and Related Words
Suberized (adj): Impregnated with or containing suberin.
- The outer bark cells are heavily suberized, giving them a corky texture. (The cells have been saturated with suberin, making them waterproof.)
Suberization (n): The process of becoming impregnated with suberin.
- Suberization occurs naturally in the bark of trees as they age. (The formation of suberin in cell walls happens over time.)
Synonyms
- Cork substance: A common reference to suberin due to its abundance in cork.
- Biopolymer: A broader term for natural polymers, of which suberin is one type.
