1. What characteristics do all plants share? All are autotrophs. All are many-celled eukaryotes. All plant cells have cell walls.

2. The p hotosynthetic pigments are the same. They have the same types of chlorophyll and other pigments.

3.  Obtaining water and other nutrients roots

4.  Retaining water cuticle – waxy covering

5.  Transporting materials some species evolved special tubes (xylem,phloem)

6.  Support cell walls and tubes help support

7.  Reproduction seed plants evolved

8. Two major groups.  Nonvascular plants -- Lack a well-developed system of tubes for transporting water and other materials.  Low growing.  No roots for absorbing water from the ground. (rootlike, stemlike,leaflike )  Pass materials from cell to cell. Thin cell walls.  Live in damp, shady places.

10.  Liverworts Hornworts leafy thalloid

11.  Vascular plants --  Plants with true vascular systems – tubes for transport.  True roots, stems and leaves  Better for dry areas.  Quick and efficient material transport.  Vascular tissue provides strength, stability, support.  What are the largest and oldest living things on the planet ?

15. Nonvascular  Moss – gametophyte is the dominant generation – it’s what we see.  It is leaflike.

16.  Seedless vascular  Fern -- sporophyte is the dominant generation – it’s what we see.  The fronds are the true leaves.

19.  The stem is underground. It’s called a rhizome. Ferns have true stems and roots.

22.  The moss male gamete must swim to the female gamete in sexual reproduction.  The fern male gamete must also swim to the female gamete. How does that happen on land?
