Developmental Anatomy

The vascular cambium cells differentiate into:

- phloem - xylem

What ultimately causes each meristematic cell to differentiate?

DNA

Roots grow downward by cell differentiation.

False.

Nearly all meristematic cells of different plants appear to look alike.

True.

Old phloem cells become:

bark

That part of a woody stem, or tree, that is outside the vascular cambium

bark

A crosswise elongation of cells within the stem will produce a ________ or _________.

branch, leaf

One of the tissues making up bark is

cork.

The maturation of a cell produced by a plant meristem

differentiation

The term used to describe the condition whereby cells begin to specialize is

differentiation

The first step after production by a meristem

elongation

The chemicals first activated in the seed that help cause other chemicals to react are called

enzymes

Another name for growth of a seed or breaking seed dormancy is

germination

The youthful, undifferentiated cells of root and shoot tips

meristem

Cells that multiply and produce growth at various parts of a plant are:

meristematic

The cells that stay young, not elongating, not differentiating are cells of the

meristems

Differentiated cells which take on the function of food storage are:

parenchyma

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

perennial

During cell division, energy is needed. The first chemicals to be broken down to use as energy in cell division are called

starch

The meristematic cells under the bark forming a ring around the tree are the

vascular cambium

The meristematic cells which produce new cells increasing plant body girth

vascular cambium

The width of a tree increases through direct growth of the:

vascular cambium

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

wood

Another name for the interior wood is

xylem
