Plant Structure and function Hall
Terms in this set (45)
above-ground organs (leaves, stems, flowers)
below-ground organs (roots)
function for absorption of water and minerals, anchorage, food storage (some), reproduction (some)
function to translocate water and minerals to the leaves; transport food (sap) downward from the leaves to the roots
function as the major photosynthetic (food making & gas exchange) organ of a plant
the movement of water, minerals, nutrients and hormones through the roots, stems, and leaves of plants
layers of dead cells that make up bundles of tissue that transport water and minerals from the roots, through the stems, and to the leaves of a plant - (Up!)
a tissue composed of living cells that make up bundles of tubes that transport food to all parts of the plant - (Down!)
hairlike outgrowth of a plant root that absorbs water and minerals from the soil
Stomata (sgl. stoma)
pores found in the leaf and stem that are used for gas exchange
the loss of water from a leaf through the stomata; this evaporation of water helps water travel up the plant as if being sucked up a straw
embryo of a living plant that is encased in a protective covering and surrounded by a food supply
the prerequisite to fertilization; the transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower
the process in which a flowering or coniferous plant emerges from a seed and begins growth
brightly colored structure just inside the sepals; attracts insects and other pollinators to a flower
outermost circle of flower parts that encloses a bud before it opens and protects the flower while it is developing
tendency of plants to grow toward a source of light
response of a plant to the force of gravity; also called geotropism
response of plants to touch
type of thin root that makes up a highly branched root system
large vertical plant root with many smaller branches
structure of a plant that supports leaves and flowers
outer covering or "skin" of a plant
system of tube-shaped cells that branches throughout a plant and transports water, mineral nutrients, and organic molecules
vascular tissue that transports water and dissolved minerals from the roots of a plant to the shoots
vascular tissue that transports food from a plant's leaves to its roots and other parts
meristem located in the tip of a root or the bud of a plant shoot
outgrowth of a root's epidermal cell that increases the surface area available for absorption
force that helps push water up the xylem in a plant
one of a pair of cells that open and close the stoma of a plant by changing shape, allowing gas exchange with the surrounding air
The __________ absorbs most sunlight for photosynthesis.
The _______ connects to the stomata and exchanges gases for photosynthesis.
Plants evolved from
An angiosperm that has only one seed leaf.
An angiosperm that has two seed leaves
A flowering plant which forms seeds inside a protective chamber called an ovary.
A plant that produces seeds that are exposed rather than seeds enclosed in fruits
A water-conducting and supportive element of xylem composed of long, thin cells with tapered ends and walls hardened with lignin.
the attraction of the surface of a liquid to the surface of a solid
Stems are made from:
node, internode and but
horizontal underground stems
The stalk of a leaf, which joins the leaf to a node of the stem.
Evaporation of water from the leaves of a plant
