Plant Morphology
• Flowers• Stem• Leaves• Fruits• Roots
Plant Morphology - Roots
• Functions– Absorb water & minerals– Anchor plant
Plant Morphology - Roots
• Root Systems• Fibrous• No main root• Fast absorption of surface water
• Holds soil – prevention of erosion
Plant Morphology - Roots
• Root Systems• Tap• 1 main root• Smaller secondary roots
• Strong anchorage
• Absorbs deep water
Plant Morphology - Roots
• Modified Roots• Prop roots• Support
Plant Morphology - Roots
• Modified Roots• Climbing• Support
Plant Morphology - Roots
• Modified Roots• Aquatic
Plant Morphology - Roots
• Modified Roots• Food & water storage
Plant Morphology - Stems
• Herbaceous Plant
Plant Morphology - Stems
• Woody Stem– Terminal bud– Axillary bud– Lenticels– Leaf scar– Terminal bud scar
