science chapter ten
Terms in this set (66)
plants belong to kingdom
they are producers, eukaryotic and multicellular, have tissues, have plastids (chloroplasts), have cell walls containing cellulose
study of plants
roots, stems, leaves
three types of plant organs
do not have nodes
attach to stems at nodes
region of the plant where leaf is attached
one or a few main roots that are thicker and longer than the other plant roots
taproot system examples
fibrous root system
cluster of roots that are equal in size and have several branches
fibrous root system example
hard and not very flexible stem with strong thick cells
woody stem example
softer, more flexible with less supporting cells
herbaceous stem examples
house plants, flowering plants
The flat green part of a leaf. Edges are smooth, tooth, or lobed. Types are simple leaf or compound
water and sugar conduction tissues in leaves
3 types of leave venation
parallel, palmate, pinnate
veins branch from base leaf
1 main vein with smaller branches
leaves connected to a stem by the
alternate, opposite, whorled
3 types of patterns
alternate leaf pattern
only one leaf attached at a node
opposite leaf pattern
two leaves attached at each node
whorled leaf pattern
three or more leaves per node
cell wall, and plastids
What are 2 important organelles of plant cells?
cell walls are made of _________. which is made of long chains of sugar molecules.
turgor pressure is caused by
water inside the cell walls. High pressure makes the plant stiff
plastids are necessary for the plant to make and store _________
tissue made of long, hollow cells that carry water from the roots to the stems and leaves. (like a drinking straw)
tissue that carries a sugar solution from the leaves to the other parts of the plant. these are not hollow tubes
arrangement of xylem and phloem in leaves and young plants
long, narrow, thick-walled cells that support the vascular bundles. Example: cornstalks
the outermost tissue of leaves, young roots, and young stems.
a protective, waxy covering in many leaves called
layer outside the xylem of a tree trunk
layer between the xylem and the bark
outermost layer of the bark made of dead cells
layer of living cells just under the dead cork that constantly divides with mitosis
dead cork cells do not expand as the tree grows so they can break apart
Why is bark rough in texture?
1st step of water transpiration: water enters through the _______.
2nd step of water transpiration: water is transported through the ____________.
3rd step of water transpiration: water exits through the ____________.
most plants use ___________ cellular respiration to convert sugar from photosynthesis to usable _________.
supply needs of plant cells and helps carry out plant functions
how a plant uses sugar
if plant cells make more sugar than needed, __________ transports sugar to other parts of plant.
cellulose (cell walls)
some sugar is bonded together to make _______________
some sugar is stored and forms _______________ (corn, potatoes, bananas).
some sugar is stored as _________________ (corn oil, olive oil, peanut oil)
starches, and lipids
consumers use energy obtained from eating ___________ and _______________ stored in plant cells.
1st factor for plant growth: sugar absorbed through ______________
2nd factor for plant growth: _________ produced from photosynthesis
3rd factor for plant growth: ___________ like the right soil and the right light
4th factor for plant growth: ________________, substances affecting how tissue grows
the growth responses of plants to their environments are called __________
___________________ growth response of a plant to light. If a plant turns toward the light, its called _________ tropism
_________________ plant's response to touch. Some plants __________ to the plant is growing near.
plant's response to gravity
reversible, repeatable plant movements. depends on changes in turgor pressure
tulip blooms/closes, venus flytrap
nastic movement examples
plant's response to the length of time it is exposed to light.
growth regulators in plants sensitive to light
bloom when days are short and nights are long
bloom when days are long and nights are short
bloom regardless of amount to light as long as conditions are right
