  1. Angiosperm Anatomy Test Vocabulary

  2. 1. Anther • At end of stamen. Produces pollen.

  3. 2. Calyx • The set of sepals

  4. 6. Corolla • The set of petals

  5. 8. Filament • Thin part of stamen that supports the anther.

  6. 11. Ovary • At the base of a carpel. Where seeds develop. Becomes the fruit.

  7. 15. Petal • Non-sexual, often showy part of a flower used to attract pollinators.

  8. 16. Pistil • The set of carpels in a flower. Often used synonymously for “carpel”

  9. 17. Pollen • Released by anther. Produces sperm.

  10. 20. Sepals • Non-sexual flower bud scales. Sometimes showy.

  11. 21. Stamen • The male reproductive structure. Made up of anther and filament.

  12. 23. Stigma • The sticky receptive tip of a carpel.

  13. 24. Style • The “tube” between the stigma and ovary on a carpel

  14. 28. Blade • The flattened, photosynthetic, part of a leaf.

  15. 29. Compound leaf • A leaf divided into leaflets.

  16. 36. Palmately compound leaf • Leaflets radiate from a common point.

  17. 39. Petiole • Leaf stalk

  18. 41. Pinnately compound leaf • Leaflets branch off a mid vein, like the pinna of a feather

  19. 44. Simple leaf • A leaf with a single blade, not divided into leaflets.

  20. 47. Vein • Clump of vascular tissue in leaves

  21. Added: Tendril • A thin, modified leaf, used for grasping a support

  22. Added: Stomata • Leaf pores for gas exchange

  23. 50. Bark • Outer layer of stem outside the vascular cambium.

  24. 53. Epidermis • Single surface layer of cells on the outside of a young stem.

  25. 54. Internode • The section of stem between nodes

  26. 55. Meristem • The zone of dividing cells. In stems, it’s in the vascular cambium.

  27. 56. Node • Often swollen point on a stem where leaves and buds attach.

  28. 57. Phloem • Also called “inner bark.” A single layer of live cells outside the vascular cambium that transports plant products through plant

  29. 61. Vascular cambium • Single layer of meristem tissue, produces xylem inside and phloem outside.

  30. 63. Xylem • Stem tissue on the inside of the vascular cambium that conducts water up a plant. The major component of “wood.”

  31. 64. Adventitious root • Roots that arise from somewhere other than the normal root zone

  32. 65. Diffuse roots • Roots divided equally among several roots (no tap root). Can be FIBROUS or FLESHY.

  33. 66. Root hair • Tiny projections near the end of a root that aid in absorption.

  34. Rootcap • A protective layer of tissue that protects the tender tip of a root and its meristem zone.

  35. 68. Taproot • A root system consisting of one main root, like a carrot.
