1. The ____________ contain the male parts of a flower (the _________ and the __________
2. The ____________ contain the female parts of a flower (the _________,________& the _________
3. In some flowers the pistil and stamen mature at different times. This forces the what kind of fertilization? __________________

19. Flowers are the plant's reproductive structures.
Angiosperms are plants that bear fruits and flowers.
“Perfect” flowers both male and female.
“Imperfect” flowers are either male or female.
Most flowers and are brightly colored to attract insects to help them carry pollen used for sexual reproduction.

20. Some flowers are not colorful – like grass
Some flowers are not colorful – like grass. These flowers usually use the wind for pollination.
This flower has both male and female reproductive parts.

26. Inflorescences

27. Vascular tissue
Transport water, nutrients and food between roots and shoots
System of xylem and phloem cells
Varied organization in roots & shoots

28. Xylem cells Tracheids Vessel elements Transpiration
Tapered, pits on ends, less capillary action vs. vessel elements
Primitive plants
Vessel elements
Pits on sides, open ends
Stacked to form long tubes
Advanced capillary action
Less primitive plants
Transpiration
Roots → shoots → leaves → out

29. Phloem cells Sieve tubes Companion cells Translocation
no nucleus nor organelles
Open sieve plates
Companion cells
Nucleated
Adjoined to sieve tubes via plasmodesmata
Controls sieve tubes; regulates movement
Translocation
Movement of sugars; sources to sinks
leaves → roots, fruits, &/or meristems

30. Plant Structure Apical meristem Ground meristem Mitotic division
Stem & root tips
Primary growth (length)
Ground meristem
Ground tissues:
Parenchyma – large; storage
Collenchyma – smaller; flexible support
Schlerenchyma – lignified; rigid support; woody
Cambium
Mitotic secondary growth
e.g. Vascular cambium
e.g. Cork cambium

31. Leaf bud
Ground meristem

32. Leaf bud Apical meristem
Mitotic embryonic tissue of stems and root tips
Primary growth (linear

33. Monocot root Dicot root
Vascular bundles centered in roots
Cortex = outer layer
Pith = center tissue
Stele = pith + vascular tissue

38. Vascular bundles Cambium Xylem, phloem, and cambium in between
Scattered throughout monocot stems
Organized around periphery of dicots

46. Fruit – ripened ovary that protects the seeds
Layers of the ovary
Pericarp
Mesocarp
Endocarp

47. Fleshy fruits One or more ovarian layer is fleshy Drupe Berry Pepo
Endocarp is hardened; pit or stone
Peaches, nectarines, apricots, etc
Berry
All or most pericarp is fleshy
Grape, tomato, etc
Pepo
Berry with hard thick rind
Melons, pumpkins, etc
Hesperidium
Berry with leathery rind
Citrus
Pome
Swollen receptacle around ovary or core
Apple, pear

48. Dry fruits Lacks fleshy tissue Dehiscent fruits Indehiscent
Split along a seam to disperse seeds
Legumes – two seams
Capsules – multiple seams
Bean, pea pods, peanuts, etc
Indehiscent
Do not split on a seam
Achenes, grains, nuts
Corn, wheat, etc

49. Simple fruits Aggregate fruits Multiple fruits Accessory fruits
Single ovary of one flower
Aggregate fruits
Many ovaries of one flower
Multiple fruits
Many ovaries of many clustered flowers (inflorescence)
Accessory fruits
Tissue other than ovary ripens (swollen)
