Document Summary

Concept 35. 1: plants have a hierarchical organization consisting of organs, tissues, and cells. Plants have organs composed of different tissues, which in turn are composed of different cell types. An _____organ__ of several types of tissues that together carry out particular functions. A ___tissue__ group of cells consisting of one or more cell types that together perform a specialized function. Figure 35. 2 three basic organs evolved: roots, stems, and leaves. A root is an organ with important functions. The primary root is the first root to emerge. The primary root branches to form __lateral roots___ which improve anchorage and water absorption. Tall plants with large shoot masses have a taproot system. The _____taproot_ develops from the primary root and prevents the plant from toppling; lateral roots are responsible for absorption. Small or trailing plants generally have a fibrous root system, which consists of. Adventitious roots that arise from stems or leaves. Lateral roots that arise from the adventitious roots.
