Xylem (tracheids)
- long tapered cells
- thickened lignin walls with pores
Type of tissue and observable features
Epidermis (root hairs)
- Long projections of cytoplasm
- thin cell walls
- tightly packed
Function of meristematic tissue
- For plant growth
- Initially undifferentiated
- Make new cells
Function of sclerenchyma
- lignin thickening strong
- Provides structure
- support of various regions of the plant
