3. What are the four major groups of plants?
4. List 3 characteristics of each major plant group.
5. List the steps of the conifer life cycle in order.
6. List the divisions of the gymnosperm.
7. List the steps of the angiosperm life cycle in order
8. Fill in the blanks:
The outermost layer of a flower is made of ________, which protect the flower. Just inside the outermost layer is another layer of modified leaves called _________, which can be brightly colored to attract pollinators. Most flowers have both male and female structures. A ___________ is the male structure of a flower and it has a stalk called a____________. This stalk supports an_________, which produces the male gametophytes: ___________. The innermost part of the flower is the female structure called the__________. Each female structure has three parts. The __________is the top part that is sticky and holds the pollen grains when they land there. The ___________is the tube that leads from the top part of the carpel to the base of the flower. This is called the__________, and it is where female gametophytes (eggs/ovules) are produced.
