  1. Kingdom Plantae

  2. What is a plant -multi-cellular, eukaryote -mainly sexual reproduction -autotrophic, contains chloroplast (photosynthesis) -cells have cellulose cell walls • Related to algae • Non-motile (cannot move on their own)

  3. Roots • Roots - anchor plants and take up water & nutrients

  4. Stems -Vascular tissue - Transports water and minerals from roots to the rest of the plant -xylem – transports upward (makes rings of trees) -phloem – transports downward (right under bark) Capillary action – adhesion & cohesion working together to move water.

  5. Leaves • Leaf- contain chlorophyll and conduct photosynthesis • stomata – small openings in leaves which allow plants to release water for transpiration. (guard cells open and close stomata) • Cuticle- a waxy waterproof layer on top of leaves to keep water in.

  6. Plant Generations • Sporophyte – diploid stage (tree, shrub,grass) • Gametophyte – haploid reproductive stage (pollen, spores)

  7. Non-Seed Plants • Sexual reproduction by uniting egg and sperm in water to make spores. • Bryophytes – lack vascular tissue (ex. Moss) • Pterophytes – have vascular tissue. (ex. Fern)

  8. Seed Plants • Reproduce sexually by uniting egg and pollen (sperm) through pollination to make seeds (plant embryos). • Gymnosperms – use cones to disperse seeds ex. Pine trees • Angiosperms– make flowers and use fruit to disperse seeds ex. Maple

  9. Attracting Pollinators and Dispersing Seeds Attracting Pollinators • Colors of flowers, scent, nector, mimicry Seed Dispersal • Eating fruit, wind, water, hooks

  10. Plant Adaptations Geotropism—a plant’s response to gravity (roots) Phototropism—a plant’s response to light (leaves) Thigmotropism—a plant’s response to touch (vines)
