dermal, vascular, ground
The cuticle protects agaist _________ loss.
Some epidermal cells have tiny projections known as _________, which may give a leaf a fuzzy apperance.
Dermal tissue in roots contains _________ cells that help absorb water.
How can water move from one tracheid into a neighboring cell?
by openings in the specific xylem called tracheids, it's walls are connecting to neighboring cells.
How can materials move from one sieve tube element into the next?
The end walls of sieve tube elements have many small holes through which nutrients move from cell to cell in a watery stream.
long, narrow xylem cells with openings in their cell walls
the substance in the cell walls of dead tracheids that makes wood tough
xylem cells arranged end to end on top of one another
Sieve tube elements
the main phloem cells
cells that support the phloem cells and aid in the movement of substances
are regions of the plant that produce new cells by mitosis
are found in the growing tip of a root or stem.

main type of ground tissue in plants that contains the vells with thin cell walls and large central vacuoles.
type of ground tissue that has strong, flexible cell walls; helps support larger plants.
type of ground tissue with extremely thick, rigid cell walls that make ground tissue tough and strong.
What are the three principal organs of seed plants?
roots, steams, and leaves
protective outer covering of a plant
