1. Plant Organs
Structure, Functions & Adaptations

2. 3 main functions absorb water and dissolved minerals from the soil
anchor the plant in the soil
store carbohydrates

3. Structures & Functions
Cells change structure to become specialized in structure and function.
Epidermal cells become root hairs and
internal cells become xylem and phloem.

4. Structures & Functions
Cells change structure to become specialized in structure and function. Epidermal cells become root hairs and internal cells become xylem and phloem.
Cells no longer divide, they lengthen pushing the tip of the root through the soil

5. Structures & Functions
Cells change structure to become specialized in structure and function. Epidermal cells become root hairs and internal cells become xylem and phloem.
Cells no longer divide, they lengthen pushing the tip of the root through the soil
parenchyma cells that help protect the growing tissues as the root grows

6. Structures & Functions
Cortex: made of parenchyma cells that transport and store water, minerals and food. All materials pass through on their way to the vascular tissue

7. Structures & Functions
Cortex: made of parenchyma cells that transport and store water, minerals and food. All materials pass through on their way to the vascular tissue
Endodermis: one-cell thick, regulates lateral movement of water

8. Structures & Functions
Cortex: made of parenchyma cells that transport and store water, minerals and food. All materials pass through on their way to the vascular tissue
Endodermis: one-cell thick, regulates lateral movement of water
Epidermis: produce root hairs

9. ADAPTED FOR ABSORPTION
Root Adaptations
ADAPTED FOR ABSORPTION
Epiphytic plants are adapted to absorb moisture from the AIR.
These plants grow on other plants (or a building) with their roots hanging down.
Ex: Orchids

10. Root Adaptations ADAPTED FOR AERATION
Pneumatophores roots that are adapted to absorb oxygen from the AIR.
These plants grow are found in extreme wet conditions.
Ex: Mangrove

11. Root Adaptations ADAPTED FOR SUPPORT
Prop roots are adapted help support the plant. (Also called stilt roots)
These roots grow out from lateral branches.
Ex: Sugar cane & Maize

12. Root Adaptations ADAPTED FOR STORAGE
Tap roots & tubular roots & some rhizomes
are adapted to store water and sugars.
That is why they are a good food source.
