Questions And Answers
, Homo habilis - CORRECT ANS:Shorter than modern. Large brains with large speech regions. They came
from Australopithecines
Homo floresiensis - CORRECT ANS:coexisted with modern homo sapiens, but were much smaller in
stature, most likely due to island dwarfing.
Cro-Magnons - CORRECT ANS:traveled from Africa to Western Europe around 40,000 years ago and may
have been first hominids to have language
Neandertals - CORRECT ANS:larger brains than modern humans, larger muscles, shorter/thicker bones,
massive brow ridges and wide, flat noses
Petiole - CORRECT ANS:Wide portion of a leaf attaches to the stem of the plant at the petiole
Cotyledon - CORRECT ANS:the seed leaf in the embryonic plant.
Monocots have one, Eudicots have two
Xylem - CORRECT ANS:Water and minerals are pulled up from the roots through the xylem as
transpiration occurs through the stomata of plant leaves
Meristem - CORRECT ANS: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 - CORRECT ANS:more prominent in plant cells, but also in animals cells, they are responsible
for storing water, pigments, and toxin
