1. Plants

2. Plant Cells Cell walls  provide protection and structure Conduct photosynthesis – Use chlorophyll in organelle chloroplast to do it

3. Structures Cuticle  waxy, protective layer secreted onto surface of plant which holds water Cellulose  chemical compound that provides structure and support

4. Classificiation Vascular plants  use tubelike structures that carry water and nutrients throughout plant Nonvascular plants  lack tubelike structures so must use other ways to transport water and nutrients

5. Nonvascular Plants Very small plants that have rhizoids rather than roots Reproduce by spores not seeds Examples – Mosses  green, leaflike growths around stalk – Liverworts  flattened, leaflike bodies – Hornworts  one chloroplast in each cell

6. Moss

7. Liverwort

8. Hornwort

9. Plant Life Cycle Two stages – Gametophyte stage  begins when sex cells produce haploid cells called spores – Sporophyte stage  begins with fertilization
