Study Notes
Plant Structures and Processes
- Lenticels are small openings in a stem's bark that facilitate gas exchange, allowing air to enter the stem.
- Vegetative reproduction is a method of asexual reproduction where new plants grow from roots, stems, or leaves of an existing plant.
- The chief factor influencing flowering in plants is the length of day and night, which affects photoperiodicity.
Flower Anatomy
- Sepals serve as protective coverings for the developing parts of the flower, safeguarding them during growth.
- Anthers are the specific flower parts responsible for the production of pollen, essential for reproduction.
Germination and Fruit Development
- The initial step in seed germination involves the seed absorbing water, a critical trigger for the growth process.
- A fully developed fruit indicates that the ovary of the flower has ripened, signaling successful fertilization and development.
Plant Hormones
- Chemotropin is identified as not being a plant hormone, distinguishing it from other regulatory substances that influence plant growth and development.
