PLANT UNIT STUDY GUIDE 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.
