Solution
The correct option is D Lignification
- The plant tissues become woody by a process of lignification.
- Lignification is a complex process which occurs in vascular plants to strengthen the plant body.
- In this process, the complex organic molecule lignin fills the intercellular spaces between the cell wall with cellulose, hemicellulose and pectin components (in vascular tissues).
- This compound is covalently linked to hemicellulose thus, the cross-links are formed between different plant polysaccharides which provide mechanical strength to the cell wall or plant as a whole.
- They are abundantly found in the wood of plants.
- Lignin is hydrophobic in nature and thus, impermeable to water.
- So, the correct answer is 'Lignification'.
