Classification & Anatomy

Know categories of plants, distinguishing characteristics and examples of each. How do
fungi differ from plants? Know similarities and differences between monocots and dicots
(including the seeds) and examples of each. Difference between endosperm and
cotyledon. Know the cells/tissue types.

Growth

Know what simple tissue gives rise to all others. What produces xylem and phloem.
Where does mitosis take place in plants? During germination, where does food for
embryo come from? From a diagram of seed know root meristem, apical meristem of
shoot.

Reproduction

Understand Alternation of Generations. Know the dominant generation for each category
of plant. What are megaspores and microspores and what process creates them? What
are antheridia and archegonia? Who has sporangia on underside of leaf? From diagram
know a little about reproduction and reproductive parts.

Nutrients and Transportation

Nitrogen cycle N2  NH4  NO2 NO3  N2, who does what? The carbon cycle.
What happens when stomata close? The cells that translocate the greatest quantity of
organic nutrients are? What is responsible for the movement of water to the top of a tree?
Sieve cells differ from tracheids in what ways? Flow of water in xylem regulated by
versus movement of material in phloem. Know terms like guttation, cohesion, adhesion,
transpiration, osmosis. How does water move into roots? How do mineral ions move
into roots?

Hormones, chemicals and response to environment

Environmental conditions that increase photosynthesis and those that inhibit it.
What is phototropism, how does it occur and what plant growth substance mediates it?
What is photoperiod? Know plant growth regulators. Given a list of chemicals know
which does what. Response to seasonal change. Controls of the flowering response.

Evolution

 What made tracheophytes successful on land? Success of angiosperms? Pick
adaptations of plants from sea to land out of a list. What is a lichen and its relationship to
succession. Plants evolved from what general organism.
