  1. Plant Kingdom Characteristics: Multi-cellular organisms Have eukaryotic cells Cell walls contain cellulose Carry out photosynthesis with a pigment called chlorophyll & organelles called chloroplasts Called autotrophs or producers

  2. What plants need to survive: • Sunlight • Water & Minerals • Gas Exchange of Carbon Dioxide & Oxygen

  3. Photosynthesis • CO2 + H20 + Sunlight C6H12O6 + O2 • C6H12O6 is also called • Glucose • Carbohydrate • Sugar

  4. Plant Cells & Chloroplasts Q: What other organisms have chloroplasts?

  5. Plants are divided into 2 large groups Plant Kingdom! Nonvascular (Bryophyta): plants without tubes Vascular (Tracheophyta): plants with important tubes

  6. Nonvascular plants are divided into 2 groups. Nonvascular - Bryophytes Moss:lives in damp places! Liverwort: also lives in damp places!

  7. Moss

  8. Liverworts

  9. T or F. Animals reproduce sexually and plants reproduce asexually. F. The vast majority of both animals and plants reproduce sexually.

  10. Reproductive Parts- Sporophyte= asexual - Gametophyte= sexual Moss Liverwort

  11. Alternation of Generations- form of reproduction in moss/liverworts. Both sex and asex needed Sexual: The plant makes sperm and eggs. When these fertilize, spore capsule on a stick forms. Sperm and eggs produced here.

  12. Spore Capsule Asexual:The spores release, drop to the ground, and make new plants.

  13. Vascular Plants • Have tube-like cells called tracheids • Tracheids transport water, minerals and food • Allows vascular plants to be much larger than nonvascular plants

  14. Vascular Plants – 3 groups • Ferns: Reproduce by alternation of generations. • Gymnosperms: Plants with cones. “Naked Seeds” • Angiosperms: Plants with flowers. “Covered Seeds.”

  15. Most are small but some grow to 20 ft tall Ferns

  16. Fern leaves drop spores.

  17. Close up of Spore capsules Q: What other organisms reproduce using spores?

  18. Spores produce a little leaf.

  19. Lives for 2 weeks, and... produces sperm and egg

  20. A new fern grows! New ferns are called “fiddleheads”

  21. Parts of a fern – matching! a. Underground stem b. Where spores are stored c. Above ground stem d. Large leaf e. Takes up water & nutrients • Frond • Stalk • Roots • Sori • Rhizome

  22. Conifers have a male cone and female cone. The female cone produces the ovules and… The male cone produces the pollen. Fertilization of the ovule and pollen creates the seed. Gymnosperms (conifers)

  23. Gymnosperms (conifers)

  24. Conifers(cone-bearers) Male cones produce pollen (with sperm)! Pollen blows off in the wind.

  25. WOW !!!!!

  26. Conifers The female cone is big. Pollen sticks to it, and fertilizes an egg, making a seed.

  27. Angiosperms : • Most common plants • Produces pollen (sperm) & egg in flowers • Produce seeds

  28. Angiosperms

  29. Angiosperms and Gymnosperms have evolved to become the dominant plants on earth!!

  30. Questions • What organisms do you think are the ancestors of plants? • What are the differences between spores and seeds? • Why does having tracheids allow vascular plants to be much larger than nonvascular plants?
