• Multicellular• Autotrophs• Eukaryotic• Have chloroplasts and cell walls• Sexual Reproduction

Nonvascular plantsNonvascular plants

• No Vascular Tissue• Water and Food move by osmosis

and diffusion• Short (low to ground)

Vascular PlantsVascular Plants

• Have vascular Tissue• Phloem (carry food)• Xylem (carry water)• Grow Tall

• Rhizome: thick underground stem (p. 615)

Sporophyte Stage (diploid)

produces spores Gametophyte Stage (haploid) produces gametes

Seed Plants (produce seeds)Seed Plants (produce seeds)

• Gymnosperms• “naked seed”• “seed-bearing”• Example: Pine Trees• Usually produce cones• Male cones>(pollen)• Female>(egg in ovule)• Seed is not in a fruit

• Angiosperms• “flowering plants”• “have seed coat”• Produce flowers• Seeds are in a fruit• Male reproductive

part > Stamen• Female

reproductive part> Pistil
