VISUAL SUMMARY

ANGIOSPERM LIFE CYCLE

An angiosperm's life cycle showing the haploid and diploid stage.

FIGURE 24–6 In the life cycle of a typical angiosperm, the developing seeds of a flower are protected and nourished inside the ovary. Relate Cause and Effect Which two structures are the result of fertilization?

Double fertilization may be another reason why the angiosperms have been so successful. By using endosperm to store food, the flowering plant spends very little energy on producing seeds from ovules until double fertilization has actually taken place. The energy saved can be used to make many more seeds. Figure 24–6 summarizes the life cycle of a typical angiosperm.

In Your Notebook Make an outline detailing the key features of angiosperm reproduction.
