1. Plant Tissues

2. Plant Tissues There are 3 types of plant tissue: Dermal Tissue
Vascular Tissue
Ground Tissue

4. Dermal Tissue
Includes:
Epidermal Tissue
Periderm Tissue

5. Epidermal Tissue
A thin layer of cells that covers the surface of leaves, stems and roots
Root hairs are an extension of the epidermal tissue that increase the roots surface area for water and nutrient absorption
Can create a waxy cuticle to protect leaves from water loss

6. Periderm Tissue
In woody plants, epidermal tissue is replaced by periderm tissue
produces bark on stems and roots

7. Vascular Tissue Colour Changing Carnations

8. Vascular Tissue
The vascular tissue of a plant is like our circulatory system. It transports the water, nutrients and other chemicals throughout the plant.

9. Vascular Tissue
There are 2 types of vascular tissue:
Xylem
Phloem

10. Xylem
Elongated cells that, once matured, are hollow tubes with no organelles stacked end to end to create a tube from the roots to the shoots
Transport water from the roots to the leaves of the plant
Once xylem cells are mature they are no longer living tissue

11. Phloem
Transports sugars created by photosynthesis, other chemicals and hormones throughout the plant
Phloem cells are living tissue

12. Vascular tissue is arranged in 2 different ways:
Monocot – vascular bundles (one xylem and one phloem tube) are arranged randomly throughout the stem
Dicot – vascular bundles are arranged in a ring formation

13. Ground tissue is the composed of all the tissue in between the dermal tissue and the vascular tissue. It performs different functions in the different parts of the plant
In roots – storage of carbohydrates
In Stems – provides storage and support
In Leaves – performs photosynthesis
