ASSESSMENT PACK VERIFIED GRADE
◉ What would likely reduce the amount of diffusion of materials
into or out of a cell
Answer: decreasing the concentration gradient
◉ In large plants, transport in xylem is the result of
Answer: transpiration
◉ Based on your understanding of transpiration, increasing the loss
of water by evaporation in the leaves will result in
Answer: an increase in the movement of fluid in the xylem
◉ Under the Pressure-Flow hypothesis, the flow of materials in
plant tissues is always
Answer: from the source to the sink
◉ Systematics
Answer: part of biology that uses phylogeny to categorize the
diversity of living organisms
,◉ Node
Answer: Each branch point on a tree
◉ Homology
Answer: Things seems like they are related, but in reality have a very
different ancestral background
◉ Lowest category of the taxonomic hierarchy
Answer: species
◉ Convergent Evolution
Answer: organisms that are not close to being related, but share
many characteristics
◉ Peptidoglycan
Answer: complex of structural polysaccharides cross-linked by
peptides
◉ The peptidoglycan cell wall of bacteria can be stained by a specific
stain known as
Answer: gram stain
◉ Bacteria that has it's cell wall exposed to the environment
, Answer: gram positive bacteria
◉ Bacteria with a peptidoglycan wall, but also containing an extra
outer membrane
Answer: gram negative bacteria
◉ Flagella
Answer: filaments that extend from the membrane of a cell and are
used for cellular locomotion
◉ Taxis
Answer: the orientation or movement of an organism either toward
or away from a stimulus
◉ Movement toward a stimulus
Answer: positive taxis
◉ Movement away from a stimulus
Answer: negative taxis
◉ Three main types of taxis seen in prokaryotes
Answer: Chemotaxis, Phototaxis, Magnetotaxis
