  1. TODAY • Review for plant summative • Crossword Review Legless Lizard

  2. Stomata are tiny holes in the cuticle of the leaf. stoma • can open and close • allow air to move in and out

  3. Stomata open and close when guard cells change shape. stoma guard cells • Guard cells surround each stoma.

  4. A vascular system allows resources to move to different parts of the plant. water and mineral nutrients sugars • brings water and mineral nutrients up from roots • disperses sugars from the leaves • allows plants to grow higher off the ground

  5. Pollen grains allow for reproduction without water. • pollen grains contain a cell that divides to form sperm • can be carried by wind or animals to female structures

  6. A seed is a storage device for a plant embryo. • Seeds are coated for protection • embryo develops when environment is favorable

  7. Plants and other organisms can share a mutualistic relationship. a mutualism is an interaction in which two species benefit plant roots and certain fungi and bacteria flowering plants and their animal pollinators Plants evolve with other organisms in their environment.

  8. Plants have adaptations that prevent animals from eating them. • spines and thorns • defensive chemicals

  9. Nonvascular plants grow close to the ground to absorb water and nutrients. Seedless plants rely on free-standing water for reproduction. Example: Mosses

  10. Gymnosperms do not have seeds enclosed in fruit. • most are cone-bearing • pollen is producedin male cones. • eggs are produced in female cones. • seeds develop on scales of female cones.

  11. Angiosperms have seeds enclosed in some type of fruit. • Have flowers which are the reproductive structure • A fruit is a mature ovary of a flower.

  12. Flowers allow for efficient pollination. animals feed on pollen or nectar pollen is spread from plant to plant in process

  13. Annuals mature from seed, flower, and die in one year. • There are three types of plant life spans. • Biennials take two years to compete life cycle. • Perennials live more than two years. Big bluestem

  14. KEY CONCEPTPlants have specialized cells and tissue systems.

  15. Dermal tissue covers the outside of a plant. protects the plant secretes cuticle of leaves forms outer bark of trees Plant organs are made of three tissue systems.

  16. provides support stores materials in roots and stems most commonly made of parenchyma • Ground tissue is found inside a plant.

  17. two networks of hollow tubes xylem transports water and minerals up phloem transports photosynthetic products stem leaf root • Vascular tissue transports water, minerals and organic compounds.

  18. water vapor exits leaf stomata helps pull water to the top branches • Transpiration is the loss of water vapor through leaves.

  19. Roots support the plant absorb, transport, and store nutrients root hairs help absorption

  20. Stems support leaves and flowers house most of the vascular system store water Baobab trees Cactus

  21. Leaves collects sunlight for photosynthesis blade petiole

  22. Meristem (Meristematic tissue) • Undifferentiated cells/tissue • Can turn into any type of cell in the plant

  23. Cambium • Type of vascular tissue that produces new xylem and phloem • Responsible for growth rings

  24. for aquatic environments, ex: water lily • Leaves have many adaptations. • for extreme temperatures, ex: pine needles • for water loss,ex: cactus spines • for getting food,ex: Venus’ flytrap

  25. Today – Crossword Review • Fix the following errors on the crossword • In the first box for 2 down (put in the letters MO) in the same box • Cross out the first box for 8 down • On the clues portion of the crossword, cross out number 23 and write 29 • Cross out number 29 and write 23 Plant Summative Tomorrow Poisonous plant project due Wednesday

  26. Photosynthesis Monocot chloroplast Dicot pollen sperm seed gymnosperm angiosperm flowers roots stem leaves Annual Biennial Perennial Word Bank • vascular • nonvascular • xylem • phloem • dermal • meristem • guardcells • ground • cambium • transpiration • stomata • oxygen • carbondioxide

  27. (T08) explain the basic classification of plants •  (T08) identify bryophytes, pteridophytes, gymnosperms, and • angiosperms •  (T08) explain how the following plant organs and tissues are directly •  (T08) explain the role of plant tissues (meristematic, ground, dermal • and vascular tissues) with respect to plant organs
