Document Summary

12 january 2018 / module 1: plant form and function. Plant cells and plant tissues: undifferentiated cells: meristems , differentiated cells , simple plant tissues , complex plant tissues, complex plant tissues (continued) In a simple leaf; contains gland, trichome/hair, and stroma. As well as cuticle and epidermis cells (ec) Ec ec gland ec tricome ec stoma ec ec. Epidermal hairs (root) located after the root cap. Hairs are very short lived (1-3 weeks) Root epidermis is grown in between the hairs to absorb water that contains minerals that is used for the plant. Cell walls is structurally improved by silica. Uses chemical & structural defense against herbivores. The cells are cone-shaped so the light is reflected in all directions to create a sheen. Has the stomata located on the top of the leaves (stomata is usually located on the bottom)
