Presentation on theme: "Review How are tissues distributed in plant roots"— Presentation transcript:
1Review How are tissues distributed in plant roots Apply Concepts Why is it important that the root endodermis permits only a one way passage of materialsClassify Draw and label a diagram to show how roots absorb water and nutrients- also include a brief description
14Transport NutrientsActive transport brings mineral ions across the epidermisHigh mineral ions concentration causes water molecules to move into the plant by osmosis.
15Transport NutrientsWater and dissolved minerals pass through the cortex and move toward the vascular cylinder.
16Transport NutrientsVascular cylinder is enclosed by the endodermis and a special waterproof zone called a Casparian strip.
17Casparian StripForces water and minerals through the cell membranes of the endodermis rather than in between the cellsControls water and minerals entering vascular cylinder doesn’t allow to leak back out.
18Root PressureWater is forced in by osmosis due to active transport of mineralsWater enters through casparian strip and is forced up.
19Root PressureGlass tube replaced stem and leaves of carrot.
