Exam 33: Plant Structure, Growth, and Development

What two tissues transport materials throughout the entire plant body?

The secondary plant cell walls contain large amounts of lignin, which is a polymer of amino acids.

Explain how the structures of tracheids and vessel elements are specialized for their conduction of water and dissolved minerals.

The growth process that allows cells to become specialized to carry out specific functions is:

Which of the following is a chloroplast-containing cell that occurs in pairs?

Which of the following are living but lack a nucleus and other organelles at maturity?

An Arabidopsis plant that contains a mutant mp gene would most likely:

Vessel elements and tracheids develop and become specialized hollow cells via the process of programmed cell death, also called apoptosis.

The thick secondary cell walls of sclerenchyma cells are chemically distinct from parenchyma and collenchyma cells. Sclerenchyma cells contain all of the following EXCEPT:

Alpha-galacturonic acid is a six-carbon molecule that is a derivative of glucose, and is the monomer unit of which of the following?

Some trichomes function as protective stinging needles.

Plants, like animals, grow at all points of their body.

Roots, stems, leaves, flower parts, and fruits are composed of all three tissue systems. All five are therefore which of the following?

Growth that results in an increase in the length of a plant is referred to as:

When the microfibrils in the cell wall are oriented in the same direction, the cell will expand in a direction parallel to the microfibrils. ____________________
