-
Alteration Of Generations
- plants and some species of algae. Includes both diploid and haploid
- multicellular stages.
-
Sporophyte
- the spore-producing individual or phase in the life cycle of a plant having
- alternation of generations
-
Gametophyte
- the gamete-producing individual or phase in the life cycle of a
- plant having alternation of generations
-
Cuticle
- Waxy coating on the exposed surface of a
- plant
-
Roots
- absorb and distribute waters and minerals and anchors the
- plant
-
Stem
- Positions the leaf where it can get optimal
- sunlight
-
Leaves
- Capture sunlight, releases H2O and
- O2
-
Stomata
- pores on a leaf that open and close to let CO2 in, O2 out, and
- regulate water
-
Xylem
- Conducts water and minerals up the plant, consist of tracheids
- and vessels
-
Phloem
- regulate sugar sap to keep the plant and stem
- alive
-
Rhizome
Large underground fern root
-
-
Fiddlehead
immature coiled frond
-
Angiosperm
- plants having seeds in a closed
- ovary
-
Herbaceous
- characteristic of a nonwoody herb or plant
- part
-
Dicot
- has two cotyledons, branched veins, flower parts in multiples
- of 4 or 5
-
monocot
- has one cotyledon, parallel veins, flower parts in multiples of
- 3
-
Sepals
- protect the developing bud, in the outermost
- whorl
-
petals
- designed to attract pollinators, in the 2nd
- whorl
-
stamen
- male reproductive structure, in the 3rd
- whorl
-
filament
- part of the stamen that supports the
- anther
-
anther
- part of the stamen that produces
- pollen
-
pistil
- female reproductive structure in the 4th
- whorl
-
stigma
- part of the pistil, a sticky top which pollen lands
- on
-
style
- part of the pistil that connects the stigma to the
- ovary
-
Taproot
- main root of a plant growing straight downward from the
- stem
-
Fibrous Root
threadlike, branched root.
-
Root Cap
- dead cells at the tip of the root that protect the root as it
- grows
-
Zone of Cell Division
- The zone of primary growth in roots consisting of the root
- apical meristem and its derivatives. New roots cells are produced in this
- region.
-
Zone of elongation
- region of the root where cells begin to grow in
- size
-
Zone of Maturation
- Region of the root where cells begin to take on specialized
- jobs and functions
-
Whorl
ring of leaves around a stem
-
apical meristem
- a tissue that carries out primary
- growth
-
Epidermis
- Outermost tissue of a plant which acts as a barrier and absorbs
- minerals and water
-
Cortex
Storage cells of a plant
-
Endodermis
- boundary around the vascular tissue that regulates what enters
- or leaves the tissue
-
Pith
- Storage cells inside the vascular
- tissue
-
Stem
produces and supports leaves
-
Venation
- the arrangement of veins in a
- leaf
