a flowering plant. Has its seeds enclosed in an ovary.
a mature ovary
multicellular body produced by mitotic division of the diploid zygote.
reproductive cells produced by meiosis in a mature sporophyte
multicellular body that has haploid cells and produces gamets, egg, and sperm
fibrous root system
mat of thin roots that spread out below the soil surface
what is the advantage of a fibrous root system?
It extends the plant's exposure to soil water and minerals and anchors it to the ground.
one large vertical root that produces many small lateral, or branch roots.
What is the advantage of a taproot system?
Taproots anchor the plant to the ground, store food hat supports flowering and fruit production.
Monocots have a (taproot, fibrous) system.
Dicots have a (Taproot, fibrous) system.
extentions of individual epidermal cells on the root surface.
what is the function of root hairs?
increase surface area to maximize water and mineral absorption.
The presence of a terminal bud is partly responsible for inhibiting the growth of axillary buds in a phenomenon called
What is the advantage to apical dominance?
Allows the plant to grow tall fast.
removal of terminal buds
What is the main photosynthetic organ of most plants?
What is the difference between monocot and dicot leaves?
Most monocots have parallel major veins that run the length of the blade (grass), while dicot leaves have a multibranched network of major veins (maple leaves.)
a single layer of tightly packed cells that covers and protects all young parts of the plant.
waxy coating of leaves that helps the arial parts of the plant retain water.
continuous throughout the plant and is invlolved in the transport of materials between roots and shoots.
vascular tissue that conveys water and dissolved minerals upward from roots into shoots
transports food mafe in mature leaves to the roots and to nonphotosynthetic parts of the shoot system.
tapered elongated, dead cells within the xylem that moves water from cell to cell and has secondary walls with lignin.
structures within the phloem tha tform chains of cells to move sucrose, organic compounds, and some mineral ions. They are alive at functional maturity, although they lack a nucleus, ribosomes, and a vacuole.
tissue that is neither dermal tissue nor vascular tissue.
ground tissue internal to vascular tissue in dicots
ground tissue external to vascular tissue in dicots
What are the funtions of ground tissue?
photosynthesis, storage, and support.
perpetually embryonic tissues (stem cells of plants)
