|
Plants that make their own food are
|
autotrophs
|
|
|
the gas plants give off is
|
oxygen
|
|
|
photosynthesis uses sunlight to convert water and CO2 into
|
oxygen and high energy sugars
|
|
|
plants are green because chlorophyll doesn't
|
absorb green light
|
|
|
in the chloroplasts, stroma is the space that surrounds the
|
thylakoids
|
|
|
light dependent reactions occur in the
|
thylakoid membranes
|
|
|
products of light dependent reactions are
|
oxygen gas, ATP, and NADPH
|
|
|
in light dependent reactions
|
ATP and NADP are not used to produce high energy sugars
|
|
|
the calvin cycle takes place in the
|
stroma
|
|
|
what is produced during the Calvin cycle?
|
high energy sugars
|
|
|
if CO2 is removed from the atmosphere
|
fewer sugars will be produced
|
|
|
a plant is a
|
multicellular eukaryote
|
|
|
not all plants produce
|
seeds
|
|
|
the first plants evolved from
|
an organism similar to multicellular green algae
|
|
|
bryophytes don't have vascular tissue therefore they
|
don't conduct water through tubes, grow close to the ground, and can draw only a few cm of water (all of the above)
|
|
|
xylem and phloem are not present in
|
bryophytes
|
|
|
xylem tissue is important because it
|
can conduct water over long distances
|
|
|
a seed plant is anchored by its
|
roots
|
|
|
ground tissue is found in a plants
|
roots, stems, and leaves
|
|
|
what is produced in new plant cells?
|
meristematic tissue
|
|
|
if a student is looking at a microscpe for cell reproduction, what part of the plant should they look at?
|
the tip of a shoot
|
|
|
vascular tissue consists of
|
xylem and phloem
|
|
|
if the xylems of a young tree are destroyed, then the tree can't
|
conduct or transport water to the leaves
|
|
|
minerals from the soil move into roots by
|
active transport
|
|
|
the main function of the stems is to
|
transport substances between roots and leaves
|
|
|
primary growth of a stem
|
increases the length of the stem
|
|
|
oxygen produced by photosynthesis diffuses out of the leaf through
|
the stoma
|
|
|
the attraction of water molecules is
|
adhesion
|
|
|
the tissue that water moves through by capillary action is
|
the xylem
|
|
|
the pollen producing male reproductive structure of the flower is the
|
stamen
|
|
|
in alternation of generations, what is the diploid phase?
|
sporophyte
|
|
|
gymnosperms produce seeds that are
|
developed uncovered within cones
|
|
|
angiosperms produce seeds inside protective structures called
|
ovaries
|
|
|
to produce spores, all plants undergo
|
meiosis
|
|
|
bryophytes need standing water to
|
reproduce
|
|
|
in a fern the spores that are released from the sporangia are
|
not haploid
|
|
|
the structure that holds the plant embryo, food supply, and a protective covering is a
|
seed
|
|
|
the specialized structure that evolved most recently is the
|
fruit
|
