Plant Development

The study of growth characteristics of a plant is called developmental

Morphology

Flowering plants are classified as:

angiosperms

A plant that completes its life cycle from seed germination through fruit and seed production within a year's time.

annual

The food for the embryo plant comes from the cotyledon or

the endosperm

Evolution theory is based on the supposition that energy plus matter plus natural chemical combinations are sufficient to ultimately produce functioning interrelated complex systems.

true

The meristematic cells which produce new cells increasing plant body girth; often forming a ring only several cell layers wide in woody stems and roots.

vascular cambium

That part of a tree that is interior to the vascular cambium; the xylem of a tree.

wood

A plant that germinates, grows, produces flowers and seeds, and dies in a year is termed a(n

annual

That part of a woody stem, or tree, that is outside the vascular cambium; includes phloem and cork.

bark

A seed leaf; may store (dicot) or absorb (monocot) food in seeds of flowering plants.

cotyledon

(dicot). A flowering plant with seeds having two seed leaves, e.g., bean.

dicotyledon

The maturation of a cell produced by a plant meristem; cells may mature to form fibers, parenchyma, vessel members, etc.

differentiation

In the maturation process of cells, the first step after production by a meristem; a lengthening of the cell assisted by water intake in living things to occur; an organic catalyst.

elongation

A food storage tissue which assists in seed development in flowering plants; may or may not be apparent depending upon the stage of seed maturation.

endosperm

A running down, or related to the physical law of an increasing tendency for disorganization.

entropy

In order for a plant to grow, it must overcome the basic universal law of

entropy

A seed consists solely of a protected package of elements, nutrients and plant food requiring only water and solar energy.

false

An annual plant bears fruit or flowers every year.

false

Energy plus matter is sufficient for continued development of order, complexity or growth.

false

(Select all that apply.) Which of the following does the plant need in order for it to germinate and develop?

genetic info energy matter

The beginning of the development of a plant from a seed is called

germination

The youthful, undifferentiated cells of root and shoot tips and other plant parts that produce new cells for growth in size and girth.

meristem

(monocot). A flowering plant with seeds having one seed leaf, e.g., corn.

monocotyledon

A plant that continues to grow year after year from the same plant body.

perennial

A plant that continues to live for many years is termed a(n)

perennial

Two ancient ___________ plants cited in the text are the bristlecone pine and the giant sequoias.
