BIOL-1507EL Lecture Notes - Lecture 1: Adventitiousness, Taproot, Vascular Tissue
Document Summary
In asexual reproduction the offspring are derived from a single parent without genetic recombination. The result would be a clone which is genetically identical organism to the parent. In apomixes there is no joining of sperm and egg. Growth and development of the vegetative plants (organization of the plant body) The plant body has hierarchy of organ tissues and cells. Plants like multi-cellular animals have organs composed of different tissues and these tissues are composed of cells. The basic morphology of a vascular plants is organised into a root system and shoot system. Tap root system: most dicots and gymnosperms plants, consisting of one main vertical root (tap root) that develops from embryonic root (root radical) The tap root gives rise to lateral root. Fiberous root system: a mat of generally thin roots spreading out below the soil surface, with no roots standing out as the main one. This type of root found main in most monocot (mainly grasses)
