The main vegetative parts of plants include
roots, stems, and leaves
What is NOT a function of plant roots
produce energy that the plant can use to carry out metabolism
The point at which one or more leaves attach to the stem of a plant is a
node
Internodes of plants are
located on the stems
What is NOT a function of plant stems
absorption of water from soil
The opening and closing of a plant's stomata is regulated by the flow of ____________ ions
potassium
The type of plant cell that provides support without interfering with growth and is familiar as the "strings in celery" is a
collenchyma cell
The type of plant cell that provides rigid support and is dead at maturity is a
sclerenchyma cell
The ________ transport(s) water and dissolved minerals from the roots of the plant to the shoots of the plant.
xylem
The main phloem-conducting cells are
sieve tube elements
The conducting cells of the xylem are called
tracheids and vessel elements.
A waxy layer secreted by the epidermal cells of a plant is the
cuticle.
The pores through which leaves exchange gases with the atmosphere are
stomata
The part of a plant that is the stalk-like part of a leaf is the
petiole.
Compound leaves are defined as being divided into
leaflets.
Stems that grow underground and produce roots and new shoots are
rhizomes
The primary organ of photosynthesis in a plant is the
leaf
The root cap
-secretes a lubricant for the growing root
-protects the meristem from abrasion
-is located at the tip of the root
-plats a role in sensing gravity
Which best describes a compound leaf?
multiple leaflets attached to a single petiole
The innermost layer of the cortex of a plant root is the
endodermis
Carbon dioxide enters a plant from the atmosphere through pores called
stomata
If a plant exhibits determinate growth, the plant
stops growing when the plant reaches its mature size.
The source of a plant's new cells is a type of plant tissue called its
meristem
The tissue that produces cells to thicken a root or stem is the
lateral meristem
The secondary xylem and phloem are produced by the
vascular cambium
