Wildlife Biology Start a new entry task page!! Conifers and Deciduous Trees – Field Sampling techniques ENTRY TASK (ET) : Write three characteristics that could help you identify trees LEARNING OBJECTIVE (LO): Distinguishing identifying characteristics in conifers

TODAY’S PLAN Collecting conifer samples Identifying distinguishing characteristics

Distinguishing Characteristics With your group, observe the samples at each station Record notes in your binder as you move through stations When back at your tables, discuss with your group what characteristics would be the most helpful to try and identify each tree/sample Come up with at least three characteristic that you all agree and write them on the small whiteboards Have a spokes person ready to share with the class

Plant evolution

Wildlife Biology ENTRY TASK (ET) : Get a handout from the front of the room and SILENT read the first page LEARNING OBJECTIVE (LO): Identifying conifers using dichotomous keys

TODAY’S PLAN Identifying conifer samples collected yesterday

Wildlife Biology ENTRY TASK (ET) : How many pine samples you observed yesterday? What was a characteristic that distinguished pines from other samples? LEARNING OBJECTIVE (LO): Identifying conifers using dichotomous keys Understanding how seed plants reproduce

TODAY’S PLAN Finish Identifying conifer samples and handout questions Life cycle of a gymnosperm

Homework due tomorrow Thursday READ THE PACKET ON SEED PLANTS AND TAKE NOTES ON A SEPARATE PAPER

Douglas fir Western Red Cedar

Pines

Bryophyte life cycle   The gametophyte is the dominant generation

Diversity of bryophytes MOSSES LIVERWORTS HORNWORTS

SWORD BRACKEN LADY LICORICE FERNS

Ferns Horsetails Club mosses

  The sporophyte is the dominant generation in the pteridophytes’ life cycle

Gymnosperm diversity Ginkgo Cycads Gnetophytes Conifers Western Hemlock

Douglas fir Western Red Cedar

In gymnosperms the sporophyte generation is dominant

Plant evolution

Plant Classification Based on: 1. 1.Vascular system   Tubes that carry water & nutrients throughout plants 2. 2.Reproductive structures I. I.Spores – single cell II. II.Seeds – have many cells & food for the embryo plant a. a.Gymnosperms – put seed in cones b. b.Angiosperms – put seed in flower ovary

Plant Classification Key

Wildlife Biology ENTRY TASK (ET) : What is the evolutionary advantage of having seeds? LEARNING OBJECTIVE (LO): Why prairie ecosystems are endangered

TODAY’S PLAN Prairie ecosystems research in preparation for the Pierce College presentation tomorrow

Research of Factors Affecting Prairie Ecosystems Use the websites provided on class webpage to research and answer the following questions: What are some of the threats that affect prairie ecosystems in South Puget Sound? What species of plants and animals are threatened? What organizations are involved in prairie restoration projects? What are the solutions that are been worked out to restore the prairies? Why is it important to restore and protect the prairie ecosystem? With your group, prepare a report that answers these questions. After the presentation tomorrow, we will be incorporating additional information to your report.
