Chapter section and review questions
AP Biology Unit 9 Plant Structure and Function

The plant kingdom includes thousands of species, which have established themselves in
every possible habitat. With such a wide range of habitats, plants naturally taken on a
dazzling variety of forms. There are over 260,000 different species of flowering plants
alone.

You need to be familiar with the general characteristics, life cycles, and classifications of
plants. We have already covered some of these characteristics in the last unit. You
should recall that plants:

      Are ____________________, eukaryotic organisms.

      Have a __________________ made of __________________ for support.

      Are _________________________, meaning that they convert light energy to

    ________________ energy by means of chloroplast located primarily in their leaves.


      Take up ________________ via capillary action.



Plant Classification (review)

Describe each of the following groups.

      Green algal ancestor

Nonvascular

      Hornworts

      Liverworts

      Mosses

      Whisk ferns

      Horsetails

      Ferns

include the movement of K+.




Water movement

Describe the different factors that control the movement of water through a plant.
AP Biology Unit 9 Plant Structure and Function

Plant Hormones

The growth and development of plants are controlled by substances known as
hormones. There are five classes of plant hormones, which affect division,
elongation, and cell differentiation.

Complete the following chart: Functions of Plant Hormones
    Hormone                   Function             Location in Plant

important for the plant to complete, listing all of the plant hormones involved and
describing their function:
       (a)    elongation of the plant shoot.
