Document Summary

A growing axillary bud gives rise to a lateral shoot, complete with its own apical bud, leaves, and axillary buds. Removing the apical bud stimulates growth of axillary buds, resulting in more lateral shoots. That is why pruning trees and shrubs and pinching back houseplants will make them bushier: describe the structure and function of five types of modified roots, prop roots, storage roots. Store food and water in their roots: strangling aerial roots, buttress roots. A horizontal shoot that grows just below the surface. Vertical shoots emerge from axillary buds on the rhizome: bulbs. Vertical underground shoots consisting mostly of the enlarged bases of leaves that store food. You can see the many layers of modified leaves attached to the short stem by slicing an onion bulb lengthwise: stolons. Horizontal shoots that grow along the surface. These runners enable a plant to reproduce asexually, as plantlets form at nodes along each runner: tubers.
