Study Notes
Sclerenchyma
- Sclerenchyma cells are characterized by their rigidity, which results from the presence of secondary cell walls.
- Secondary cell walls in sclerenchyma are primarily composed of lignin and cutin, contributing to their strength and durability.
- These cells play a crucial role in providing structural support to plants, allowing them to maintain their shape and withstand various stresses.
- Sclerenchyma also reduces the likelihood of herbivory by making the plant tissues less palatable or harder to digest.
Sclerenchyma Cell Types
- Fiber Cells: These are slender and elongated cells that are often found in various plant parts, providing tensile strength and support.
- Sclereid Cells: Also known as stone cells, these are shorter and irregularly shaped, contributing to the hardness of certain plant tissues, such as seed coats and fruits.
