bisc 131 exam 3 with complete solutions
water moves from ? water potential to ? water potential
high, lower
water journeys from soil to ? to roots to ? to leaves
root cells, stems
from soil to root cells:
-increasing ? of solutes in root cells creates ? water potential
-water moves to root cells from ?
concentration, low, soil
from roots to stems:
-cohesion and adhesion draw water up the ?
xylem
intermolecular forces between water molecules caused by the polar nature of water;
responsible for surface tension
cohesion
attraction between water molecules and other molecules
adhesion
from stems to leaves:
-? causes negative water potential in leaves
transpiration
loss of water vapor to the atmosphere through stomata
transpiration
water moves from ? to leaves
xylem
photosynthesis produces ?
photosynthates
example of photosynthate?
sucrose
photosynthates are produced by sources, example ?
leaves
photosynthates are transported to ?
sinks
example of sinks?
roots, young shoots, developing seeds
translocation:
sugars are moved from source to phloem by ?
, active transport
active transport costs ?
energy
translocation:
osmosis causes water to move from nearby xylem to ?
phloem
transport of water through a semipermeable membrane according to the water's
concentration gradient across the membrane that results from the presence of solute that
cannot pass through the membrane
osmosis
osmosis increases ? in phloem
water potential
translocation:
-phloem contents move to ?, which have lower water potential
sinks
animals are heterotrophs: ?
carnivores, herbivores, omnivores, parasites
animals:
-(most) have complex ? ; no cell wall and ?
tissue structure, extracellular matrix
animals:
-? life cycle
diplontic
in animals, multicellular form is ?
diploid
animals:
-most are motile, some are ?
sessile
able to move independently by expanding energy
motile
unable to move independently
sessile
animals:
-complex development, fixed ?
body plan
animal reproduce ?
sexually
animal sexual reproduction: ?
egg + sperm = zygote
animal embryonic development:
-? divides, without growing in size, several times
-? occurs as an indentation in the blastula forms
zygote, gastrulation
zygote divides, without growing in size, several times
cleavage
16-32 cell stage
