2. Calyx The set of sepals

6. Corolla The set of petals

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

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

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

17. Pollen Released by anther. Produces sperm.

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

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

23. Stigma The sticky receptive tip of a carpel.

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

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

54. Internode The section of stem between nodes

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

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

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

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

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

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