Pollination enables gametes to come together within a flower

Ian Konrad 4-23-14 LEH Mrs. Guido Flower Anatomy Activity 1a. Record the number of sepals observed in your flower specimen and give 1 function. There were 12 sepals on my flower. One function of the sepals is to protect the flower while it is forming a bud. 2a. Record the number of petals - what advantage do colorful petals provide for the flower? There were 6 petals on my flower. Colorful petals attract pollinators such as bees to come and pollinate the flower. 2b. Why are sepals considered accessory parts of the plant? Sepals are considered accessory parts of the plant because they are not directly involved in pollination. 3a. Record the number of stamens and give 1 function.

The spirals could go both clock-wise and counter-clock- wise. The number of spirals running in the two directions is known as the Fi-

Plant Diversity I: How Plants Colonized Land Chapter 29 Overview: The Greening of Earth For more than the first 3 billion years of Earth?s history, the terrestrial surface was lifeless Cyanobacteria likely existed on land 1.2 billion years ago Around 500 million years ago, small plants, fungi, and animals emerged on land ? 2011 Pearson Education, Inc. Since colonizing land, plants have diversified into roughly 290,000 living species Land plants are defined as having terrestrial ancestors, even though some are now aquatic Land plants do not include photosynthetic protists (algae) Plants supply oxygen and are the ultimate source of most food eaten by land animals ? 2011 Pearson Education, Inc.

39.2 Plant hormones 131095 SunHa Lee cytokinins - 2) apical dominance Apical dominance: ability of the apical bud to suppress the development of axillary buds Direct inhibition hypothesis: auxin & cytokinins act antagonistically in regulating axillary bud growth - auxin: sent from apical bud, directly inhibits axillary growth - cytokinins: sent from roots, signals axillary growth Ratio of auxin and cytokinins is important 2) apical dominance Apical bud removed: no inhibition of axillary buds, more lateral branches Auxin added: lateral bud growth repressed Overload of cytokinins: more lateral branches, bushier 3) anti-aging effects Slow aging - inhibit protein breakdown - stimulate RNA and protein synthesis - mobilize nutrients from nearby tissues
