  1. Chapter 8 Review

  2. What parts of a fern grow underground? • Roots and stem

  3. T/F: Vascular and nonvascular plants differ in the way they transport materials. • True

  4. What is auxin? • A plant hormone that speeds up the growth of plant cells

  5. What food making process occurs in the leaves? • Photosynthesis

  6. What are the characteristics of plants?(Hint, there are 4) • Eukaryotes • Multicellular • Autotrophs (even though some can also be heterotrophs, ALL are still autotrophs) • Have cell walls

  7. What are structures B and C? Are they male or female? • B=filament • C=anther • Male

  8. Where on a fern are spores located? • Underside of the leaf (frond)

  9. What do spores that plants produce develop into? • Gametophytes

  10. What produces the egg and sperm cells during a plant’s life cycle? • Gametophytes

  11. What are the functions of vascular tissue? (Hint: there are 3) • Transport materials • Provide structure to the plant • Hold up the leaves to expose them to sunlight

  12. What are the 2 stages of a plant’s life cycle? • Sporophyte and gametophyte

  13. What do xylem and phloem transport? • Xylem=water and minerals; goes up • Phloem=food/sugar; goes down

  14. What is structure A? What is its function? • Cuticle • Helps prevent water loss during transpiration

  15. Name the 3 parts of a seed. • Embryo=young plant • Stored food • Seed coat

  16. T/F: Phloem forms annual tree rings. • False; xylem

  17. What characteristic do all gymnosperms share? • All produce naked seeds

  18. What are cones? • Reproductive structures on gymnosperms

  19. Which group (monocot or dicot) has scattered bunches of vascular tissue? • Monocot

  20. In angiosperms, what forms after the zygote? • A fruit

  21. What determines when a plant will flower? • The amount of darkness it receives

  22. Name an example of a vascular plant. • There are many; anything except for mosses, liverworts, and hornworts

  23. What are structures E, F, and G? Are they male or female? • Stigma • Style • Ovary • Female

  24. T/F: Some seed plants are nonvascular. • False. All seed plants are vascular.

  25. What group of plants produce “naked” seeds? • Gymnosperms

  26. Name an example of a monocot. • The most common are grasses, corn, tulips, and lilies.

  27. What are fronds? • Fern “leaves” or leaf-like structures

  28. Which can live better in dry environments – seed or seedless plants? • Seed; seedless plants require water for fertilization

  29. What group of gymnosperms are most diverse? • Conifers (the group containing pines, cedars, etc)

  30. Which group of plants produce fruits? • Angiosperms

  31. What is the difference between angiosperms and gymnosperms? • Angiosperms produce seeds that are enclosed in fruit • Gymnosperms produce seeds that are “naked”, often using cones

  32. How long do perennials live? • More than 2 years

  33. How are angiosperms useful to people? • Food • Medicine • Clothing

  34. What is does structure D contain? • Xylem and phloem

  35. What is required for seed germination? • The seed must absorb water

  36. What passes through the stomata? • Gases (carbon dioxide and oxygen are the main ones we focused on)

  37. What is the function of a root? • Absorption of water and minerals • Anchoring the plant • Storing food

  38. What is the function of root hairs? • Absorption • Anchoring

  39. What is dormancy? • When the plant stops or slows its growth • This is similar to hibernation in animals
