Study Notes
- Leaf buds can sometimes turn into flower buds.
- All parts of the flower are modified leaves.
- Sepals protect the ovary, petals attract pollinators.
- Carpels can be simple or compound pistils, which house ovules that become seeds.
- Incomplete flowers lack one or more floral organs.
- Floral modifications increase reproductive success, including inflorescences and nectar spurs.
- Male gametophytes develop from microsporangia, female gametophytes from megasporangia.
- Female gametophytes consist of egg cells and polar nuclei, enclosed by integuments that become the seed coat.
- Double fertilization occurs when pollen grains fertilize both the egg cell and polar nuclei, resulting in a seed with two entry points for water imbibition.
