Introduction to the Diversity of Plants

Name __________________________

Please include the questions in your submission.

10 Points Each

1.       Define the term plant.

2.       List the types of plants that are found in each of the following groups:

          Nonvascular Land Plants

          Vascular Nonseed Plants

          Gymnosperms (Define Gymnosperm and give examples.)

          Angiosperms (Define Angiosperm and give examples)

3.       Discuss the importance of plants to us under the following headings:

          Oxygen and carbon dioxide interactions

          Sources of food

          Sources of commercial products

          Sources of energy (list the sources)

4.       What is autotrophic nutrition? 

          Compare it to heterotrophic nutrition. 

5.       Define photosynthesis and write its equation. 

          Plants store their carbohydrate food in the form of what molecule?

6.       What kind of cells do plants have?  Define this term. 

          What structure surrounds and protects the plant cell? 

          Name the molecule that composes this structure. 

7.       What are chloroplasts? 

          What is the function of chlorophyll?        

8.       Explain the concept of Alternation of Generations. 

          Define the stages that alternate in the plant life cycle.  Define the terms haploid and diploid and include these terms in your definition of the stages.

          Explain how the stages alternate from one stage to the other during the life cycle.  (How do we get from a gametophyte to a sporophyte?) 

9.       Compare plant cells and animal cells by completing the following table.  Include 6 characteristics.

Comparison of Plant Cells and Animal Cells

10.     Discuss the changes in structure that have evolved to adapt plants to live on land.  Include the changes that have reduced the loss of water, permit gaseous exchange on land, and are responsible for transport.
