Plant Form and Physiology Part 1

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


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


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.


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


The pores through which leaves exchange gases with the atmosphere are


The part of a plant that is the stalk-like part of a leaf is the


Compound leaves are defined as being divided into


Stems that grow underground and produce roots and new shoots are


The primary organ of photosynthesis in a plant is the


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


Carbon dioxide enters a plant from the atmosphere through pores called


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


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
