22.4 Flowering Plants

Understand Key Concepts

  1. In angiosperms, the mature seed is surrounded by a structure called a

    1. cone.

    2. flower.

    3. fruit.

    4. cotyledon.

  2. A plant that has a two-year life cycle is a

    1. dicot.

    2. monocot.

    3. biennial.

    4. perennial.

  3. How do fruits aid in seed dispersal?

  4. How does the pattern of veins in a monocot leaf differ from that in a dicot leaf? Draw an example of each.

  5. Give one example each of a woody plant and an herbaceous plant.

  6. How does the life span of an annual differ from that of a perennial?

    Think Critically

  1. Compare and Contrast Describe the methods of reproduction and development in the five major plant groups. Include information about the size of the mature plants.

  2. Compare and Contrast Compare the size and function of gametophytes in bryophytes, ferns, and seed plants.

Connecting Concepts

Use Science Graphics

  1. Classify Study the photograph of the flower below. Is this plant a monocot or dicot? Explain your answer.

A flower with blue and white petals.

Write About Science

  1. Explanation Choose a particular group of seedless vascular plants and a particular group of seed plants. Then, write a paragraph that compares reproduction in these two groups.

  2. Assess the At first glance, an oak tree and a zebra hardly seem similar in any way. Describe the characteristics that they do share in common. What are the characteristics of the oak tree that distinguish it from the other kingdoms of living things?

Analyzing Data

A homeowner has noticed moss growing in the backyard lawn and wants to understand the conditions that cause moss to grow where grass had grown before. Half the homeowner's property is in shade all year, and the other half gets direct sun. The table shown summarizes his observations.

  1. Interpret Tables It is clear from the table that moss grows best in areas shaded from the sun. If one of the years in the table had below average rainfall, what would be your guess as to which year that was, based on the data given?

    A table showing "Growth of moss in Sun and shade."d

  2. Form a Hypothesis What hypothesis about the difference between the shaded and the sunny areas would explain the observed growth of moss?
