Roots

Leaves
100
Wood is essentially composed of these cells which carry water upward in a tree
What is xylem
100
Mosses, hornworts, liverworts compose this family.
What are bryophytes?
100
Turnips, Carrots, and Beets would be this type of root.
What is a taproot?
100
Corn and ragweed both have this stem structure which grows back each year.
What is an herbaceous stem?
100
Flattened structures of the leaf designed to catch sunlight
What are the blades?
200
Rapidly dividing cells that are found in the apical portions of the root and shoot.
What is meristematic tissue
200
Seeds are covered, flowering plants.
What are Angiosperms?
200
While not true roots, these structures on mosses are root like in their action.
What are rhizoids?
200
These specialized stems for storing food are often thought to be roots - a good example is the potato
What is a tuber?
200
Outer waxy layer just above the upper epidermis
What is the cuticle?
300
Composed primarily of collenchyma, this filling in a herbaceous stem has another name.
What is pith
300
Ginkgoes belong to this category of seed plants
What are gymnosperms?
300
Plants use these specialized root structures to radically increase the amount of surface area for water absorption
What are root hairs?
300
Oak, maple, and pine all exhibit this type of stem structure which has annual rings.
What is wood stem?
300
These specialized cells in a leaf control transpiration and maintain turgor
What are guard cells?
400
Bryophytes lack this type of tissue as they primarily operate by osmosis.
What is vascular tissue
400
Mosses have two segments, the sporophyte which contains spores, and this segment which photosynthesizes to produce energy
What is the gametophyte?
400
Erosion control would capitalize on this type of root.
What is a fibrous root?
400
An outer protective layer on a stem contains cork, cork cambium and some old phloem cells.
What is bark?
400
From the Greek for 'mouth' these openings act as pores on a leaf.
What are stomata?
500
Xylem and Phloem will afford a plant the ability to grow tall, however, it is this special substance that makes the cell walls rigid.
What is lignin.
500
Ferns are unique in that they contain vascular tissue, but do not reproduce by seeds. This puts them in a unique category.
What are Pterophytes?
500
This one way valve ensures the water entering a plant does not exit the plant.
What is the Casparian Strip?
500
This wood tissue contains active Xylem cells which transport water and minerals
What is sapwood?
500
This specialized layer begins to sever a leaf from the stem based upon hormone control.
What is the abscission layer?
