BISC 101 Plants; QUESTIONS WITH
COMPLETE SOLUTIONS.
Barrier system
Immune system of plants
Primary growth
Growth in vascular plants resulting in elongation of the plant body
Root cap
protects the root from injury as the root grows through the soil, secretes slime, determines
direction of growth
Meristem
Undifferentiated plant tissue from which new cells are formed
Cell elongation
Growth of length
Cell differentiation
the process by which a cell becomes specialized for a specific structure or function.
Stomata
pores on the leaf where O2 exits and CO2 enters
lateral roots and root hairs
Increase SA of root system
, Pericycle
Outer ring of vascular tube
Phloem
Living vascular tissue that carries sugar and organic substances throughout a plant
xylem and phloem
"tubes" transport food and water throughout the plant
Xylem
The vascular tissue through which water and nutrients move in some plants, on the inside
parenchyma cells
Main cells, thin flexible primary walls
Collenchyma cells
Thicker primary cell wall, strands that support plant shoots
sclerenchyma cells
Plant cells with very thick primary and secondary walls fortified with lignin
Tracheids
tube-shaped cells that carry water and minerals up from the roots
Sieve tubes
a column of phloem cells in a plant
