First:germination Second: growth Third:maturation Fourth:death

Old phloem cells become:

bark

dicot

bean

The four main zones of a root tip are all of the following, except

cotyledon

The inevitable process causing increase in -blank- in the universe and loss in useful energy is called entropy.

disorder

The four parts of a seed include all of the following, except

epidermis

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

The facts of why onion cells produce an onion and not a walnut are well known to scientists.

false

The meristematic cells of a carrot could produce a tree or an elephant just as easily.

false

The root cap cells elongate and differentiate forming phloem and xylem.

false

Trees get wider when vascular cambium adds new phloem to the rings of wood inside.

false

endosperm

food supply, not part of the embryo seed plant

cotyledon

food supply, part of the embryo seed plant

monocot

grass

differentiate

maturates, develops specialized function

A dicot may be expected to have:

netted veins vascular rings

enzyme

organic catalyst, helps to cause other reactions

annual

plant that grows and dies in a year

entropy

running down

A seed may be described as a packaged miniature factory.

true

Meristematic cells of different kinds of plants may look alike, but the DNA messages are different.

true

The vascular cambium is one example of cells that are meristematic, that is, staying young or continuing to divide.

true

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

vascular cambium

wood

xylem

meristem

youthful tissue (keeps growing)
