The process where a plant
makes sugar from sunlight,
water and carbon dioxide
What is
photosynthesis?
The process where a
plant loses 90% of the
water that it takes up in
the roots
What is
transpiration?
Every living
thing does this
What is
respiration?
Taking in oxygen
and giving off
carbon dioxide
What is respiration?
All life on earth
depends on this
What is
photosynthesis?
Mosses
Ferns
Gymnosperms/Conifers
Angiosperms/Flowering plants
What are the 4 main
groups of plants?
According to whether the
have true leaves, stems or
roots; whether they flower
or make cones
What is how
plants are
classified?
They can be monocots or dicots,
they all flower
They all have true leaves, stems
& roots
What are
angiosperms/flowering
plants?
This sub-group of flowering
plants has fibrous roots,
parallel veins in their leaves,
has to be watered frequently,
includes grasses
What are monocots?
They do not have
real/true leaves, stems or
roots; they have to grow
where they will be in
direct contact with water
What are mosses?
Asexual reproduction of a
plant through the removal of
a piece of plant tissue and
application of rooting
hormone and proper
environment.
What is a cutting?
Leaf, stem and root.
What are the plant
parts/tissues cuttings
are started from?
3 x the size of the seed
What the proper
planting depth for a
seed?
Water and temperature
What are the two most
important factors in
getting a seed to
sprout?
Germination
What is the sprouting
of a seed?
A vine with tendrils
wrapping around a
post.
What is
thigmotropism?
Thigmotropism
Phototropism
Gravitropism/Geotropism
What are the three
plant tropisms?
We were testing this
in the corn seed lab
What is affects of
gravitropism on seed
germination?
This can make a plant grow
lopsided – more leaves will
grow on the side of a plant
nearest a light source (like a
plant near a window)
What is phototropism?
A venus flytrap uses this to
capture insects
What is
thigmotropism?
Takes in and releases
carbon dioxide, water,
oxygen and does
photosynthesis
What are the leaves?
Holds the plant up,
water travels up the
plant and sugars travel
down
What is the stem?
Anchors the plant,
takes in water and
oxygen from the soil
What are the roots?
Attracts pollinators,
often colorful,
sometimes has a scent
What are the flowers?
Contains all the
genetic information to
start another plant
What is the seed?
