Homo habilis - Shorter than modern. Large brains with large speech regions. They came from Australopithecines Homo floresiensis - coexisted with modern homo sapiens, but were much smaller in stature, most likely due to island dwarfing. Cro-Magnons - traveled from Africa to Western Europe around 40,000 years ago and may have been first hominids to have language Neandertals - larger brains than modern humans, larger muscles, shorter/thicker bones, massive brow ridges and wide, flat noses Petiole - Wide portion of a leaf attaches to the stem of the plant at the petiole Cotyledon - the seed leaf in the embryonic plant. Monocots have one, Eudicots have two Xylem - Water and minerals are pulled up from the roots through the xylem as transpiration occurs through the stomata of plant leaves Meristem - Specialized tissue that enables plants to be capable of growth throughout their entire lifespan When located at tip of stems and roots it is referred to as the apical meristem and is responsible for growing these tissues in length. Vacuoles - more prominent in plant cells, but also in animals cells, they are responsible for storing water, pigments, and toxinGolgi Apparatus - a series of membrane stakcs that receive proteins from the endoplasmic reticulum. These proteins are modified and sorted before being discharged into secretory vesicles
