CRUCIFORM is shaped like a cross.<br />
CULM is the elongated straw or hollow stem of grasses. The culm usually supports the<br />
<strong>in</strong>florescence.<br />
CULTIVAR is a plant that is a cultivated (bred) variety.<br />
CUTICLE is the fatty or waxy outer layer of epidermal cells that are above ground.<br />
CYME is an <strong>in</strong>florescence where the central flower opens first.<br />
DAMPING-OFF is the destruction of seedl<strong>in</strong>gs by one or a comb<strong>in</strong>ation of pathogens<br />
that weaken the stem or root.<br />
DECOMPOSERS are <strong>org</strong>anisms like fungi and some bacteria that break down and<br />
digest the rema<strong>in</strong>s of <strong>org</strong>anisms.<br />
DECOMPOSITION is the decay or breakdown of th<strong>in</strong>gs <strong>in</strong>to more basic elements. For<br />
example, after a plant dies, it decomposes <strong>in</strong>to <strong>org</strong>anic nutrients.<br />
DEHISCENT is a structure on some plants that opens to release seeds or pollen gra<strong>in</strong>s.<br />
DEHISCENT FRUIT splits open when it is mature, caus<strong>in</strong>g the dispersal of its seeds.<br />
Some dehiscent fruits <strong>in</strong>clude cotton, poppy, peanuts, milkweed, magnolia, and all beans.<br />
DICOT (Class Magnoliopsida) is a type of flower<strong>in</strong>g plant (an angiosperm) whose seed<br />
has two embryonic leaves (cotyledons). The leaf ve<strong>in</strong>s are usually net-like (and not<br />
parallel). Taproots are often present. Beans and peas are examples of dicots.<br />
DICHOTOMOUS VENATION is a pattern of leaf ve<strong>in</strong>s <strong>in</strong> which the ve<strong>in</strong>s branch <strong>in</strong><br />
two over and over aga<strong>in</strong>. Ferns are dichotomousy ve<strong>in</strong>ed. A few angiosperms and<br />
gymnosperms (like g<strong>in</strong>gkos) have dichotomous venation.<br />
DIOECIOUS has the male and female flowers on different plants (Compare with<br />
monoecious). For example, date trees are dioecious.<br />
DISEASE is any disturbance of a plant that <strong>in</strong>terferes with its normal structure, function,<br />
or economic value.<br />
DORMANCY is a period <strong>in</strong> which a plant has no active growth <strong>in</strong> response to harsh<br />
environmental conditions (like droughts or cold seasons).<br />
ECOSYSTEM is the <strong>in</strong>terrelationships between all of the liv<strong>in</strong>g th<strong>in</strong>gs <strong>in</strong> an area.<br />
EMBRYO is a develop<strong>in</strong>g plant still <strong>in</strong>side the seed. The embryo has cotyledons<br />
(embryonic leaves), a root cap, a food source and a plumule (shoot), all located <strong>in</strong>side the<br />
protective seed coat.
