trichomes, guard cells, and epidermal cells

The genes that initiate flower formation are

floral meristem identity genes

parenchyma

A vascular bundle:

contains xylem and phloem

A region of cell division in a plant is called a

meristem

Arrange the structures found in a typical leaf blade from inside to outside.

Vascular bundle, mesophyll, epidermis

Artichoke hearts are tender and tasty, the leaves are too, but most of an artichoke leaf is fibrous and impossible to chew. The leaves must contain lots of

sclerenchyma cells

According to the ABC model of floral development, a showy ornamental flower with multiple sepals and petals but no stamens or carpels would express

A, C, and E

A root hair is

An extension of an individual cell and structure that absorbs water from soil

Plants grow by primary and secondary mechanisms. Choose the correct description of a mechanism and its result.

Primary and secondary growth are required to produce woody plants.

Plant embryos grow into seedinglys by adding new cells at only 2 growth points which are called

shoot and root apical meristems

Procambium ultimately gives rise to

primary and secondary xylem and primary and secondary phloem shoot and root apical meristems

Primary meristems are located in the ___ of the plant

root and stem tips

Pores on the leaf surface that function in gas exchange are called

stomata

Lateral roots in seed plants are initiated by cell division in the

pericycle

Intermediate growth is a characteristic of which of the following plant organs?

shoots and roots

If you were able to walk into an opening cut into the center of a large redwood tree, when you exit from the middle of the trunk (stem) outwards, you would cross, in order

the annual rings, phloem, and bark

If a cross section of a eudicot herbaceous stem were compared with the cross sectino of its root the primary difference would be

location of vascular tissue

In most leaves, chloroplast containing cells are most closely compacted in

the mesophyll

Bark becomes scarly because

cork cambium divides only parallel to the surface, and thus does not increase in circumference

Both tracheids and fibers
